Sierra Wireless MC7455 | EM7455 -- AT! Command Guide

[Jflex113]

This tutorial was originally created by Jim Helms on the original Wireless Joint forum. I have added several commands and explanations to help clarify their use. Feel free to ask questions or suggestions for adding to the list.

TUTORIAL DISCLAIMER: This tutorial is based on using a Windows PC and a Sierra MC7455 modem mounted in a
mPCIE-to-USB adapter. We will be using the a terminal from the Windows device to issue commands to the MC7455
modem. Different devices and methods to issue the AT commands may require various alterations from the
examples below. Always take caution when accessing a modem's interface. This forum, as well as the writer, will
assume NO liability for use of this information. In short, be cautious and use at your own risk.

If you are just getting started with programming the modem, there are three basic utilities required for this
method:

• Windows Connection Manager software (USB Drivers) (allowing Windows to recognize the modem)

• Latest Windows executable Generic Firmware (for the MC7455 modem)

• Huawei Terminal (to issues the commands to the modem)

Plug the USB modem into your Windows device USB port.

Install the Air Prime Driver Software on the Windows machine via the executable file.

Run the Huawei Terminal executable file as an administrator. When the terminal opens, select the white down
arrow button, and select the COM port that corresponds to the Sierra Wireless…WWAN Modem and hit the Connect
button.

If you are working with the EM7565 it is recommended to use PuTTY in Serial mode to program the modem. Refer to the bottom of this topic for more instructions.

NOTE: If the terminal does not list the Sierra modem, open the Windows device manager (Press the Windows Key +
X then Device Manager) and look at the Ports (COM & LPT) and see on what COM port the modem is located and use
that Port Number.

If you are now connected to the modem through the terminal, go the white outlined slot on the bottom of the
Terminal and type (or copy and paste) the following and hit enter:

Code: Select all

ATI

If the modem is accessible, information will be displayed showing the model, firmware and other details related to
the modem.

If you see these details, congratulations! You are now ready to begin with issuing commands.

Type, or copy and paste (one line at a time) the AT commands that follow and hit Enter after every command.

In our first command we must tell them modem we have permission to enter commands. It is important to
remember that you must first enter this command any time you access the modem to enter various other
commands. It is also used to return more thorough or detailed information when requested.

Code: Select all

at!entercnd="A710"

And, that ALL commands issued to program the modem will take effect ONLY after rebooting the modem:

Code: Select all

at!reset

By default, the MC7455 will be in QMI mode which much be changed to the MBIM mode for various OpenWRT, LEDE, and ROOter frimware builds. (The EM7455’s defaults to the MBIM mode). The AT Commands for the EM|MC7455: for MBIM composition is:

Code: Select all

at!usbcomp=1,1,1009

Other options for the EM|MC7455 modem are for QMI:

Code: Select all

at!usbcomp=1,1,10d

Another option is to expose the NMEA port:

Code: Select all

at!usbcomp=1,1,100d

The EM7465 requires a slightly different command to place it in MBIM (also, PuTTy works best for the EM7465):

Code: Select all

AT!USBCOMP=1,3,1009

To check or verify the mode configuration:

Code: Select all

at!usbcomp?

We will now add the APN (shown in this demo for Sprint as r.ispsn using an ipv4 address).

Code: Select all

at+cgdcont=1,"IP","r.ispsn"

In return we get:

Code: Select all

Send: at+cgdcont?
Recieve: at+cgdcont?
Recieve: +CGDCONT: 1,"IP","r.ispsn","0.0.0.0",0,0,0,0

You may also check what versions of IP settings are available for the modem:

Code: Select all

at+cgdcont=?

Which on the mc7455, returns:

Code: Select all

Recieve: +CGDCONT: (1-24),"IP",,,(0-2),(0-4),(0-1),(0-1)
Recieve: +CGDCONT: (1-24),"PPP",,,(0-2),(0-4),(0-1),(0-1)
Recieve: +CGDCONT: (1-24),"IPV6",,,(0-2),(0-4),(0-1),(0-1)
Recieve: +CGDCONT: (1-24),"IPV4V6",,,(0-2),(0-4),(0-1),(0-1)

This reflects that the mc7455 will allow us to take advantage of Sprint's dual stack IPV4V6 for the APN:

Code: Select all

at+cgdcont=1,"IPV4V6","r.ispsn"

Which returns:

Code: Select all

Recieve: +CGDCONT: 1,"IPV4V6","r.ispsn","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

If you find that for what ever reason you cannot connect to an IPV6 address and would like to check and see if IPV6 is enabled use the following command:

Code: Select all

At!custom="IPV6ENABLE",1

If you would like to disable IPV6 use this command:

Code: Select all

At!custom="IPV6ENABLE",0

While there are no requirements to do so, we can manually define and set our preferred bands for the modem.
(NOTE: If you are doing a new custom build of LEDE/OpenWRT, I suggest you skip the band programming and/or
locking until the build is up and running properly--the modem will automatically select the bands). But, for this
demo and using Sprint, we can assign each band a reference command which we may later use to lock the modem
to an specific band or group of bands. If you are still in the same terminal session, you can skip the first permission
command.

Code: Select all

at!entercnd="A710"
at!band=0A,"B25",0,0000000001000000
at!band=0B,"B26",0,0000000002000000
at!band=0C,"B41",0,0000010000000000
at!band=0D,"Sprint (All)",0,0000010003000000

Notice that the Sprint (All) band was created by adding together the binaries of the individual bands we selected.
Creating an “All” band holds true for all carriers and bands available to that carrier. Take special notice of
redundant numbered bands and frequencies (when listed) to assure they match those of your carrier.

If you are using a different carrier other than Sprint and want multiple bands combined into one you may find that some of those combine band binaries have letters in them. Here is an example of what that would look like using Verizon:

Code: Select all

at!band=10,"B2",0,0000000000000002
at!band=11,"B4",0,0000000000000008
at!band=12,"B5",0,0000000000000010
at!band=13,"B13",0,0000000000001000
at!band=0E,"VZW (All)",0,000000000000101A

Note: The A at the end of the binary is from combining the 2 and the 8 from bands 2 and 4.

To access what bands are available (and their binaries) we can use the following command:

Code: Select all

at!band=?

If we desire to lock the modem to a particular band, for instance band 41 to take advantage of carrier aggregation:

Code: Select all

at!band=0C

Or we could allow the modem to pick and choose between the Sprint bands in (ALL):

Code: Select all

at!band=0D

To check what bands we are locked to, we can always use the following command:

Code: Select all

at!band?

It is important to always remember what Index letter (i.e., 0c) you have assigned to what band. This is
important when using various scripts by different people who may assign them differently.

If you have created a band and would like to remove that Index letter (i.e., 0c) from the list of available lockable bands, use the following command and insert your index name:

Code: Select all

at!band=**,"",,

For example if you wanted to remove the band 25 index that we created earlier you would use the following command:

Code: Select all

at!band=0A,"",,

If you are having connection issues with the modem, then you may want to avoid locking the bands to any specific
frequency and allow the modem to connect as it wishes:

Code: Select all

at!entercnd="A710"
at!band=00

We can also set the modem to receive LTE only:

Code: Select all

at!selrat=06

Another useful command you will use often, will get the status and general connection information from the
modem such as what band you are currently connected to and signal strength.

Code: Select all

at!gstatus?

The Sierra mc7455/em7455 modem can and will store multiple different carrier firmware (i.e., generic, sprint, verizon,
etc...) which may create connection issues. To review the firmware (and/or preferred carrier) configuration:

Code: Select all

at!IMPREF?

There may be times were one needs to restore the modem to its OEM configurations. This will effectively reset any changes you have made to the modem's settings.

To restore to OEM settings:

Code: Select all

at!entercnd="A710"

Code: Select all

at!RMARESET=1

Some of the older Sierra Modems (i.e., mc7354, mc7750, mc7700...) may require a slightly different command to
restore:

Code: Select all

at!RMARESET=OEM
or
AT!NVRESTORE=1

After re-powering the modem, you are back to the OEM settings.


One note on programming the EM7565. The Huawei Terminal seems to have a conflict with issuing some commands to the EM7565. I recommend you use the Huawei Terminal to locate the COM Port number assigned to WWAN Modem , then use PuTTY in Serial mode to program the modem.

I encourage everyone to download a copy of the AT Command reference guide to better understand the various
commands.

I also encourage members to share AT commands they find useful and provide a brief description of when they are
used and what they do.

I am using an EM7565 and a WE1026 router on AT&T. When using the command AT!band?, I only see an LTE All option, with no list of bands. I would like to define Band 66 for testing, but I do not understand how I get the 16 digit band mask. I have only seen Sprint and Verizon examples so far. Thanks!

[JimHelms]

Try these using all caps:

Code: Select all

AT!ENTERCND="A710"
AT!BAND=?

[Jflex113]

As Jim said if you don't use the at!entercnd="A710" first then it won't show you the 16 digit band mask. You just want band 66 only for the band you are trying to lock to?

[rxrebel]

Correct. Currently, I am aggregating bands 2, 30, and 5. I have great signal on 2 and 30, but I am not seeing 66. I know that my tower has it, because my S8 picks it up. I was wanting to lock to it and see how it performed. If that worked, I was contemplating disabling 30 and seeing if I could aggregate 66 and 2, as 66 is 15 mhz and less congested.

[rxrebel]

This is what I see trying the above commands:

Code: Select all

AT!BAND?
Index, Name,                        GW Band Mask     L Band Mask 1    TDS Band Mask    L Band Mask 2    L Band Mask 3    L Band Mask 4
00, All bands                     100600000EC00000 00002100BA0E19DF 0000000000000000 0000000000000002 0000000000000000 0000000000000000

OK

Sorry for the formatting.

[Jflex113]

Give me a few and I can give you a copy for the em7565 of all the band masks

[rxrebel]

Thanks!

[Jflex113]

Here is all the 16 digit band masks for the EM7565. For a band 66 lock you would enter:

Code: Select all

at!entercnd="A710"
at!band=0A,"B 66",0,0,0000000000000002

Code: Select all

at!band=?

OK

Thanks! I'll give it a shot in a little while.

Just for clarity on my part, wouldn't it need to be at!band=0D,"B 66",0,0,0000000000000002 for band 66? 0A would refer to band 2, right?

[rxrebel]

For clarity on my part, would it need to be 0D instead of 0A? i don't know that I understand it.

[rxrebel]

Ok, I figured out that you must use AT!BAND=? to get the whole list. Sorry for the confusion.

[ingenium]

I followed the steps in this guide, but I'm unable to get an IPv6 address from Sprint using the MC7455 with the newest generic firmware.

Code: Select all

at+cgdcont?
+CGDCONT: 1,"IPV4V6","r.ispsn","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

I also ran:

Code: Select all

At!custom="IPV6ENABLE",1

I'm using MBIM mode with ROOter (stable as well as the new 18.06 builds). According to the logs, the modem is simply not returning an IPv6 address. It says "iptype: 0001 - ipv4" in the logs, and the IPv6 address is set to "/64" (ie, blank). Is there anything else that I can try?

Are you capable of getting an IPV6 address on the hotspot?

It is possible the SIM Card and plan (from the device) will not receive an IPV6 address. The ZTE Pocket-WiFi is one such example.

You can use any index such as 0A or 10, 11, or 12 to name a custom band. You can always change the custom band later. That is shown in this tutorial. It all depends on what your band list says

As long as you don't lock bands on your modem, you should get CA (assuming its available in your area.)

Here are the bands that I use on the EM7565 to lock and get CA. I've gotten CAx3 on T-Mobile and I only got it by locking bands. On an MC7455 you can only do CAx2 so this is not always the case.

Keep in mind that some of these band are only on the MC7455 and some of them are only on the EM7565

When using these commands make sure you change the at!band=** index to the numbers that you are not using ex. at!band=0E

HI I have the WE826-T with the EM7455 with AT&T and the LTE CA is INACTIVE. what can I do to activate it.

[JimHelms]

HI I have the WE826-T with the EM7455 with AT&T and the LTE CA is INACTIVE. what can I do to activate it.

When a router is idle (i.e., not pulling data), the CA will always show as Inactive. Running a speed test on one device (i.e., cell phone) while watching the results of AT!GSTATUS will generally make CA ACTIVE.

This is assuming your signals are adequate to receive the secondary required for CA.

[dchou4u]

Hi, thanks for the excellent tutorial. I find it very very helpful.

What is the AT command to perform firmware update to the EM7455 modem? I only can find the AT command to reset and put the modem in hold mode, but I cannot find any AT command to actually download the firmware to the modem.

Our EM7455 modem is connected to our own ARM Linux board running Linux 3.6.5. What I envision is that I would store the modem firmware images somewhere on my Linux filesystem, and I need an AT command to download these images to the modem.

Thanks

[dchou4u]

Hi, I know the MC7455 has the +CPIN command to input the PIN of the SIM card. Is there a AT command to actually change the PIN of the SIM card?

Thanks

When I run at!band=14,"B12",0,0000000000000800 I just get an ERROR

[Kuba1976]

I have a em7511. It seems always be on b2. B2 is really slow in my area and I was wondering if there is anyway to disable just band 2. I was just going to lock b4,b12,b14,b30, and b66 but can’t figure out how. Any help would be appreciated.

[morgan.neely]

I've installed the EM7455 modem, and updated to GoldenOrb on the We826-T2, and I'm using Windows 10, so I downloaded the newest USB drivers "AirPrime GenericDriverSetup_4836", which I had to sign in to Sierrawireless.com for, and also downloaded the AT&T Generic Firmware for MC7455, and the Huawei terminal app, now I'm trying to input some AT commands onto the router using a Male A USB cable to Male A USB for locking onto band 2 of AT@T, which is way better here, than band 12. My question is that my PC never recognizes the WE826-T2 from the USB to USB connection, so am I using the wrong kind of cable or something, or maybe downloaded the wrong items, because some of the links have changed, and it may be because of the whole war on Huawei thing, but I would really like to set this router for only band 2, to save from having to buy another Mofi 4500 Sim4 V2.

[JimHelms]

To update the modem firmware, you will need to install the modem in a USB to M.2 adapter (for the EM7455) or a USB to Mini PCI-E adapter (for the MC7455). Then, plug it into the Windows machine and then flash the modem's firmware.

[thejohnfist]

Is there a way to issue commands to it like these via the browser? I need to exclude band 30, causing me lots of latency issues.

[Catfish]

Newbie here trying to absorb all of this. I apologize for the long post. Recent purchase of Cradlepoint CBA850LP6 which has the MC7455 inside. I live in a rural area but do have AT&T dsl. Top speed on the dsl is 6.0 mbps down. Purchased the Cradlepoint and an AT&T iPad plan as a solution to get faster speeds. I have read through this tutorial as well as the tutorial on the Cradlepoint.

When first setting up the Cradlepoint with the included attached antennas I was surprised to get an excellent signal (4 bars)from the AT&T tower 3 milesaway Speeds were not much better than my dsl. Reading through this tread I have been able to figure out some of the AT! Commands. Some of the commands don’t seem to work. Such as AT!band? or AT!band=? I get no response from the modem. I did enter some of AT&T commands from page 3 of this thread:

AT!entercnd=“A710”
AT!band=10,”B2”,0,0000000000000002
AT!band=12,”B4”,0,0000000000000008
AT!reset

Upon entering those I essentially doubled my speeds to around 12-15 mbps down most of the time although it occasionally drops back to 7-8 mbps. Up speeds are around 1.5-2 mbps.

With all that said if I enter all the “Commands for AT&T” listed on page 3 in this thread will I increase my speeds further or do I need to do something else?

[JimHelms]

You have correctly defined and assigned Band 2 and Band 4.

Now, if you want to use those two bands for connection, you must create a group band (i.e., "0F") consisting of those two bands. Then, lock the modem to use that "0F" group:

Code: Select all

AT!entercnd=“A710”
AT!BAND=10,"B2",0,0000000000000002
AT!BAND=11,"B4",0,0000000000000008
AT!BAND=0F,"ATT 2&4",0,000000000000000A
AT!BAND=0F
AT!RESET

Next, the WAN Interface Profile in the Connection Manager for the MC400LP6, must also contain the AT Config Script:

Code: Select all

AT!BAND=0F

[Catfish]

Thanks Jim! Am I limited to 2 bands that can run (aggregate)at the same time or can I define and assign 3 or more bands?

[JimHelms]

Thanks Jim! Am I limited to 2 bands that can run (aggregate)at the same time or can I define and assign 3 or more bands?

You can create a group of three or more bands but the MC400LP6 will only aggregate two of them.

The practice of locking bands is best used to eliminate a particular band whose performance (when the modem is connected to that band) is less than desired (perhaps due to tower congestion on that band).

[Catfish]

Got it! Thank you!

[coromi52]

i have the nighthawk att and cannot login through terminal it is not the same pass. I have used dculocker and it does work and i can change bands but i want the actual pass. any help please?

[beausmith94]

If I’ve defined all of the Verizon bands in my area, and set my MC7455 to the band I defined as “All” is that the same as carrier aggregation?

[BillA]

When I run at!band=14,"B12",0,0000000000000800 I just get an ERROR

You get an error because your modem's hardware doesn't support that band.
Keep in mind you can only set the bands which are supported by your modem's hardware.

Trying to follow this guide, but getting an error every time I launch Huawei Modem Terminal.. Microsoft .Net Framework: Unhandled exception has occurred in your application...

Did you first install the Sierra Wireless driver software for Windows?

Thanks for the quick reply. I signed up at sierrawireless.com and downloaded and installed that. Tried it again from your link just in case.. but no dice

[farmy87]

Tried it on a second computer and having the same exact issue.

[farmy87]

Both computers seem to actually recognize and install the modem, I can see it in device manager.. just don't get why I can't get this terminal to work.

Modems usually create multiple ports in device manager under "Modems" and Ports (Com & LPT), depending on the mode the modem is in (MBIM/QMI/etc.)
In the terminal app make sure you select the com port which is under "Modems", not Ports (Com & LPT) which are used for diagnostics purposes only.

Hello, I am trying to band lock my EM7565 using GoldenOrb to Band 5, Band 13, and Band 66 on Verizon. I am having a really hard time understanding these AT Commands and I do not want to do the wrong thing. Can someone post the AT commands in the order I need to do it in and a brief explanation? Sorry, don't mean to be demanding or anything. I really want to learn! Thank you for any help

[Jflex113]

Do you already have the system up and running and can connect to the internet? Also what is your reasoning behind locking bands. A lot of times the em7565 is happier and more stable when not band locked with signal permitting

Yes, I am up and running and connected to the internet. For where I live, there are only a few bands that reach out to me. It seems to want to stay connected to Band 2 and aggregate with Band 66. Which is fine, but Band 2 in my area is a very poor signal. When Band 5 is selected and aggregated with Band 66 it seem to provide a more stable connection and better ratio of D/L and U/L. Also, Band 13 is the best band out here for the most stable connection and would like to test out how grouping B5+B13+B66 would be. And also to learn

[Jflex113]

Ahhh okay. That makes more sense. I'll right up a quick crash course for you on this after work and post it here

[Jflex113]

Firstly, I am soo sorry I forgot to get back with you on this. I've been extremely busy the past few weeks.

Anyway if you still need this information, here is a list of all the band masks that I currently have.

So you wanted these 3 bands together (B5+B13+B66). You take their bandmasks and add them together. Keep in mind that this is hexadecimal so letters can (and will) get involved at times when added the bandmasks together.

Code: Select all

B5      0000000000000010
B13     0000000000001000
B66     0000000000000000        0000000000000002

Your custom bandmask would look like this when they are all added together. This line of code is ready to send to the Sierra Wireless modem and in your case the EM7565. B5+B13+B66 is a pretty easy one to do.

Code: Select all

at!band=0A,"Custom",0,0000000000001010,0000000000000002

The part where it says "Custom" is going to be the name of the band and you can change this to whatever you like.

When using these commands make sure you change the at!band=** index to the numbers that you are not using ex. at!band=0A

Here are some examples of other carrier's bands and what adding their bandmasks together looks like.

[Jflex113]

You would be correct. Mine did not reflect one of the bands cause I believe the EM7565 does not support all of the Sprint bands.

[w.tenn]

When I run at!band=14,"B12",0,0000000000000800 I just get an ERROR

I got the same error but derived a solution based on info on menandmodems.


This worked to lock my mc7455 to B12 (ATT-M).

You want to associate an Index number (or profile)'04' that is unused by the modem FW. 03-05 are unused on my MC7455.
at!band=? shows the profile or 'Index' numbers of the bands currently in use by the FW, including custom Index numbers you created. You can use this cmd to make sure 04 is not used.

Enter this:
AT!ENTERCND="A710"

Next, this cmd below associates index 04 with B12. (04 was not in use on my MC7455). "LTE B12" will appear as a narrative or description for this index number (04).
AT!BAND=04,"LTE B12",0,800

send reset.
AT!RESET

After it resets, you can send the following band cmd to use Index number 04 to force and lock to B12.
AT!BAND=04

Send reset.
AT!RESET

After it resets, B12 will be locked if B12 is available and the signal strength is sufficient. Some folks say you need to power cycle but I did not find that to be the case with the WE826/MC7455. It's working here.

As previously shown in this thread:
To unlock just do:

AT!ENTERCND="A710"
AT!BAND=00
AT!RESET

[rmpickett]

Hey guys. Forgive my ignorance but how are you guys determining which bands are best in your area? Are you locking to one band at a time and doing speed tests? I've got a em7565 and so far performance is pretty good for what I'm used to (DSL). I get around 50Mb down and 10 up. I was hoping CA would be controllable on the modem side but from what I'm reading the carrier has to allow it as well. One other fact, the tower closest to me has only been live for about a month and a half so it doesn't even show on cellmapper yet. Thanks for any help.

[Jflex113]

You can figure out where the cell tower is and then use google earth to basically figure out what angle from your house is best to aim your antennas. Where are your antennas currently mounted and how high are they and how far are the antenna cable runs

Hello,

I just switched from a mofi 4500v2 to a WG3526-P + EM7411 CAT-7. I know this thread is titled for MC7455/EM7455 but was hoping the AT! commands are the same with 7411. With the mofi locked to B4 T-Mobile I was averaging 30-32mb down (a 3.5 miles on a hill from tower, as high as 55mb as lower as 10mb). With the same outdoor antennas (unmoved) and the WG+7411 i'm averaging 3-5mb down (its using B66 and/or B12). The switch was due to connection issues at peak PM usage hrs and wanting band 66+71 with better CA.

How do I lock to bands B4,B66 and B71. Zero background in programing.

Based on reading I this thread I think the below might do bands B4+B66 but was unsure on B71? Thanks in advance for any and all help.

Did you set the TTL settings? Which plan and carrier? You may be getting hit with speed throttle due to hotspot cap, that the MOFI was set to mask with TTL changes.

[Dre40]

Did you set the TTL settings? Which plan and carrier? You may be getting hit with speed throttle due to hotspot cap, that the MOFI was set to mask with TTL changes.

Thank you for taking the time to try to help. I redid testing and it came up but still lower. pretty sure due to the band for SCC (if I can lock out b12 it should force it to use b4 or b71, but b4 is a strong signal)

Yes TTL is set to 65 (same as before), have been running the mofi for 3+ years and regularly hit 350gb+ of use without issues on T-Mobile (I have 6 lines with t-mobile but use just one of them for wifi, if I ever did hit a slow down I'd swap in another though). I think it's due to it using band b12 for the CA SCC1. The Mofi was locked to just band b4 20hz (best speeds by far and I locked to avoid it switching to band 12 on occasion, which is a 5hz slow band).

The new modem is great it picks up band 4,12,66,77 really great and 66 is decently strong signal (mofi only had 12/4), signal quality has always been an issue due to trees with RSRQ of -15 to -17 (but hasn't changed any from prior). I ran a bunch of tests with the mofi at noon on a weekday and over 20 tests I averaged 32mb down, the same tests with the new Sierra (both over Ethernet) averages about 17mb down (some lower / some higher but average of 20 tests and same speed test site I used for mofi). Reason for switch was I was getting disconnects which I'm pretty sure was b4 congestion related (I live way out but in 160 home development on 5 acre parcels and this is the only internet besides SAT or copper, both of which are aweful for speeds), with the new band 66 I'm still slow after 6 on weekdays but it stays connected (YES!!!!!).

I do think the Mofi made setting up antennas nice and easy as it it auto updated the readout strength/quality db (plus a signal strength readout like a phone) every second on one screen and that allowed me to diel my 26db Bolton laser pointer antenna and wide band aux antenna in to the strongest tower for b4 (mofi didn't have band 66 or 71). Based on below the same tower (3.5 miles away) has 66 though (best I got for b4 was mid -80s for DB).

That is from the Sierra Modems, not really a feature of the MOFI. They have a great signal readout that is easy to read. The Quectels have a detailed output that has to be manually parsed for what is what. The Modem-> Connection Status screen should still give much of the info, but you wont get a port by port read out for antenna signal strength until you get into the EM160R-GL or RM5xx series modems. They have commands that can be used (AT+QRSRP)

Does anyone know how to delete the Sprint firmware from the MC7355?
I understand generic firmware is now needed for Sprint and it auto selects the Sprint firmware.
It does not properly connect. Well, it seems connected but no traffic.
I have four carrier specific firmware files in the modem.

Here are the bands that I use on the EM7565 to lock and get CA. I've gotten CAx3 on T-Mobile and I only got it by locking bands. On an MC7455 you can only do CAx2 so this is not always the case.

Keep in mind that some of these band are only on the MC7455 and some of them are only on the EM7565

When using these commands make sure you change the at!band=** index to the numbers that you are not using ex. at!band=0E

Unless you need to specifically connect to a certain band to force better performance due to one band giving worse ping times or speed, it would be best to leave the bands alone as in leave it as all bands. Is there any particular reason you're trying to lock bands?
