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.

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.

Hi Markus,

After upgrading the nRF9160 firmware from 1.1.2 to 1.3.1, the board seems to work.  I think you can close this ticket.

Thank you.
