John, thanks for reporting back.

Do the failing devices work when you downgrade from 1.3.2 to 1.3.1?

Kind regards,
Øyvind

Hello Øyvind,

We have a new board design - based on nRF9160 and nRF52840. Most PCBA's are fine - work with LTE-M - no problem - those all are running 1.3.2.

Yes - we have a serial port monitor where I can send AT Commands.

I backed up to 1.3.1 since we're using AT&T (even though we can stream data to our COAP server with no issue with PCBA's that are working as designed w/1.3.2).

App works fine on majority of PCBA's - we're just seeing this issue on a few.

AT+CEREG just returns an ERROR.

Thanks,
John

John,

are you able to send AT commands in your application? If not, I was referring to the AT client sample that you will need to program your device with (overwriting the current application).
You can try with AT+CEREG?

What SIM card are you using in your device?

From what modem FW did you upgrade? And did the application work before upgrading?

Hello Øyvind,

What AT command(s) should I run to verify the SIM is working properly?

(Not an AT command expert regarding LTE-M)

I've poked at the AT Command document - I've seen enough "not implemented" - so, I need to ask the above.

Thanks,
John

Hi John,

the DevZone team and Nordic Semiconductor are currently in a summer vacation period, some delays in answers must be expected due to lower staffing during this period. We apologize for the inconvenience.

The "ERROR: getaddrinfo failed -11" translates to

#define NRF_EAGAIN 11 /**< Resource unavailable, try again */

What version of the nRF Connect SDK are you working on? And from what modem FW did you upgrade? Are you able to run e.g. AT client to confirm network connection and that SIM is working as it should? If you are using the nRF9160: nRF CoAP client sample please confirm connection towards a public CoAP server.

[quote user=""]Is is possible the 1.3.2 firmware update failed?[/quote]

From the AT command output you provided it looks like it succeeded.

Can you please provide a modem trace and full log output from the device?

Thanks.

Kind regards,
Øyvind
