Most AT commands return ERROR

[flau]

Hi, I have a custom board built around a nRF9160.  All GPIO (P0.xx) work.  However, when I test with the at_client only AT+CGSN=1, AT+CGMI, AT+CGMM and AT+CGMR return with the expected string.  All other commands return "ERROR".  Any suggestions are very much appreciated.

Just found the +CLAC command.  When I try AT+CLAC, these are the results.

OK

Is this correct?

Hello Floyd,

are you able to successfully run through the Testing procedure of the AT Client sample? Could you provide me with a full application log of the result?

Regards,

Markus

Hi Markus,

Is the LTE Link Monitor only worked with the nRF9160DK?  Can I use it with my custom board?  I only see COM6,7,8 for nRF9160DK under the modem port selection.

By the way, I try the AT+CLAC command on the nRF9160DK and I see the full list of commands available.

But with my custom board, I only see 22 commands available.  Weird!!

Yes, you can use the LTE Link Monitor with your custom board :-) If you see 3 JLink UART ports it normally is a good sign.

Which modem firmware is flashed to the nRF9160 of your custom board? Are you able to run through the Testing procedure I mentioned?

Regards,

Markus

Hi Markus,

Thank you for getting back to me quickly.  I wasn't able to run LTE Link Monitor on my custom board.  My board is on COM4.  But LTE Link Monitor only gives me the choice of the DK COM6, 7, and 8.

Here are the information I can gather on my board with the limited AT commands.
