Mofi 4500 command for signal information

[farberm]

How do I send a command on the mofi4500 to view signal data.

I tried !gstatus? In the at command diagnostic sections and it returns ‘bad address”

try at!gstatus?

[farberm]

tried that also. Same response "bad address specified?

hmm, can you provide a screenshot of where you are trying to enter this? I'm not super familiar with the Mofi 4500 firmware.

Here is a screenshot

what options are in that dropdown that says "Default" ?

maybe also try removing the exclamation point?

[farberm]

Default
ttyUSB0
ttyUSB1
ttyUSB2
ttyUSB3

I tried them all same response?

[swwifty]

Default
ttyUSB0
ttyUSB1
ttyUSB2
ttyUSB3

I tried them all same response?

hmm, that's odd, the modem should be on one of those ttys.

did you try and remove the exclamation point?

Can you use putty to access the modem?

i've just begun my journey trying to figure out what my signal problems are, and what to do about them.

i happen to have a mofi 4500, and am using this method to execute the "hayes" commands to the modem. i believe you can get the router's webpage to specifically tell you how the modem is connected, but in truth i simply poked around until i got something.

i apologize for the messy nature of my post - i've never used a forum (if that's what this is) before; not familiar with best practices for appearances. don't know how to specify monospaced computery looking font for example.

1) login using the ssh interface rather that trying to understand the gui, or getting the diagnostics page to work. ie: putty from a pc in your network to mofi's address, default seems to be 192.168.10.1 - obviously any ssh client on any platform is fine. pc-o-centric not necessary.

2) execute this command at the shell prompt -> ls /dev/tty*

Code: Select all

root@MOFI4500:~# ls /dev/tty*
/dev/tty      /dev/ttyS0    /dev/ttyS1    /dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2

... in order to list the devices. i figured my modem was likely connected to one of the usb ports, or possibly the hardwired serial ports.

3) use some installed software to connect to serial ports. the only installed program i spotted (not a linux guru) was "screen"

4) use screen to connect to each serial device until you get one that understands you

5) for example, i did this

Code: Select all

root@MOFI:~# screen /dev/ttyUSB2 9600

and then issued the AT command to the modem. when i got an "OK" response i knew i found the right port.
btw, ttyUSB2 wasn't the 1st one i tried! the others just did nothing. amazingly doing this didn't seem to interrupt the internet connection.

Code: Select all

@tiredoldwhistler: Nice first post! Congrats!

Feel free to post another topic if you are having issues and I'm sure others will be happy to provide feedback. You mentioned signal issues.

@tiredoldwhistler: Yess, finally a place to start in the command-line.

I couldn't find many resources to assist me on how to configure the MoFi via the shell. I want to write a script I could execute from PuTTY so I don't have to use the GUI for an initial config after factory reset; how feasible is this?
