RE: Custom board using an nRf9160 with Simcard issues

Hi Martin, thanks for the answer. I updated the modem's firmware and after doing that, everything worked and I was able to get the following results.

RE: Custom board using an nRf9160 with Simcard issues

Martin Lesund — Tue, 14 Jan 2020 14:20:25 GMT

Hi Taylor,

Please run the AT-client sample on the custom board and run through the typical script in the LTE Link Monitor.

(make sure to have "Automatic requests" enabled in settings)

Send AT+CFUN=1 and then AT+CFUN? and you should see many different AT commands being sent to the device with responses.

Then please share the log with me.

What I am especially interested in is to see e.g. if the modem gets contact with the SIM card at all.

AT%XSIM?

(doc)

There could be an issue with the connection between the SIM card socket and the nrf9160 on your custom board.

Also, make sure you have the latest modem firmware on the custom board as well.

(and that you are trying to connect on the right network (nb-iot or lte-m) AT%XSYSTEMMODE?

Best regards,

Martin L.
