Hi,

we are using nrf9160 custom board. Modem connected to LTE network but it is not connected to AWS cloud service. It's giving the -111 error, means connection refused. But with same esim card connected to AWS modem version of 1.2.3.

Hi Jagadish,

I assume you are playing NCS2.2.0 nRF9160: AWS IoT with your custom board. If yes, please check if you are using nRF9160 Rev2 and confirm you have updated the modem firmware to MFW v1.3.4.

Please share the full log printout and modem trace recording, so we would be able to help you analyse more details on the communication traffic.

Best regards,

Charlie

Hi charlie,

My custom board modem firmware version is 1.3.2. Yes, it is NCS2.2.0 nRF9160: AWSIoT.

And my nrf9160 development kit MFW is 1.3.2 Our aws_iot code is working in my development kit and i have another nrf9169 custom board with MFW is 1.3.2 in this also aws_iot code is working

But is not working our new nrf9160 custom  board which is MFW is 1.3.2 

I will try to upgrade the modem firmware also and i will update you the response.

Hi Jagadish,

1) Did you require HW require for your new custom board? what is the link to this case?

2) Can you share the modem trace recording?

Best regards,

Charlie
