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.

I see the following differences when comparing my board with the nRF9160DK.

My board:

OK
Nordic Semiconductor ASA
OK
nRF9160-SICA
OK
mfw-pti_nrf9160_1.1.2
OK
351358812363189
OK
%HWVERSION: nRF9160 SICA B1A
OK
%SHORTSWVER: mfw-pti_nrf9160_1.1.2
OK

nRF9160DK:

OK
Nordic Semiconductor ASA
OK
nRF9160-SICA
OK
mfw_nrf9160_1.2.3
OK
%SHORTSWVER: nrf9160_1.2.3
OK

Maybe the firmware on my board needs to be updated.  If so, how?

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.

Thanks a lot for the feedback and my apologies for the late reply. I have been out of office for the last two days. But I’m glad to hear that everything works as expected now :-)

Cheers,
