WE826 with EP06 stuck in hostelss/phone protocol

[gscheb]

It is running ok really. Just stuck in this mode and won't take commands.
Did the bootloader and put fresh firmware on it same deal after.
Not sure how to shake this or what it is.

Two suggestions...

Try sending the commands below to change modes. If the modem is still unresponsive, then you will have to reflash it in an external modem adapter/enclosure (cannot flash it inside a router) with the firmware below.

Code: Select all

AT+QCFG="usbnet",0  < QMI/PPP/Default
AT+QCFG="usbnet",1  < ECM
AT+QCFG="usbnet",2  < MBIM

This Quectel_EP06-A_Firmware_EP06ALAR02A07M4G.ZIP file contains both the flashing app and firmware.

Its odd that your comm port is an ip address

[gscheb]

This was a router that was in the attic exposed to that heat.
Brought the router out of the attic.
Gout out the 50 Foot lmr 400 cables again as a fix until decide what going to do.
Attic install had 15 Foot wires.

It still works!
Just don't perform quite as well as the other two Quectel EP06 that I have.
This was some of the commands was doing with it before disconnected it.

Set Connection Modes
AT+QCFG="usbnet",0 - QMI/PPP/Default
AT+QCFG="usbnet",1 - ECM
AT+QCFG="usbnet",2 - MBIM

Could any of these maybe did something to it?

[Didneywhorl]

After setting those commands you HAVE to hard reboot the modem either with AT+CFUN=1,1 or a full power cycle. Otherwise it may act very odd.

[gscheb]

I did power cycle it and reboot it. And even reflashed the firmware thru bootloader.
Do you think this could be over heating related?

[Didneywhorl]

Possible.

Tried the AT command to change modes got this error = Can't open device /dev/ttyUSB.

When you say external modem adapter/enclosure you mean one of these?

Enclosure.PNG

Yes, that enclosure should work to reflash the modem.
However, you could try this emergency method if you're feeling adventurous.

Using PUTTY, login the router using the IP address 192.168.1.1, and run the command below.
You can get the VID/PID under Modem > Network Status > Modem ID, which should be
2C7C/0125 - EC25-AF
2C7C/0306 - EP06-A * your modem *
2C7C/0512 - EM12-G
2C7C/0620 - EM20-G

Code: Select all

echo 0xVID 0xPID > /sys/bus/usb-serial/drivers/option1/new_id

Then run the following command.
You can get the /dev/ttyUSB<x> under Modem > General Info > Comm Port

Code: Select all

picocom -b 115200 /dev/ttyUSB0 (or try ttyUSB1/2)

Finally, change the modem's mode via the follow commands:

Code: Select all

AT+QCFG="usbnet",0 - QMI/PPP/Default
AT+QCFG="usbnet",1 - ECM
AT+QCFG="usbnet",2 - MBIM
AT+FUN,1,1

Tried to do this. Able to log into putty using SSH. Then after that not sure what to do. Tried some of the commands and get no where with it. What do I do after logging into ip address with putty?

After you're logged into the router through SSH, you would copy and paste those "echo" commands, and see if you get some response.

[gscheb]

Get no response from the echo command. Does this mean this might be a lost cause?
If so what should be the next step?

[Didneywhorl]

Try running

Code: Select all

ATTERM

First

Do this while in putty?

[Yipzy]

Do you have a USB enclosure to test it with instead of using the native mPCI?

[gscheb]

No don't have one for this

[Yipzy]

No don't have one for this

Did you enter this in the putty?

Code: Select all

echo "2c7c 0306" > /sys/bus/usb-serial/drivers/option1/new_id

What does

Code: Select all

ls /dev/ttyUSB*

list after entering the first line?

Try

Code: Select all

picocom /dev/ttyUSB2

and see if you get a response when you type ATI

Thanks to everyone on this one. Somehow got it to work this time and got it out of hostless phone mode protocol.
Believe this command is what got me in this situation in the start of this.
AT+QCFG="usbnet",1 - ECM
Just a warning to others.

ECM mode works fine for Quectel (EC25, EP06, EM06, EM12, EM20) if you follow this https://whrl.pl/Rf6NVA by jhend. In fact, it works better even without Connection Monitor because it automatically reconnects when the connection is lost quickly. You could test it with AT command network disconnect

Code: Select all

AT+CFUN=0

then full functionality

Code: Select all

AT+CFUN=1

you should get connected again with a new IP shortly.
