Device Reboot after every 30 seconds

[Pavan Vora]

Hi, 

We have designed a custom board and just have started testing. We are observing nRF9160 device is rebooting after every 30 seconds. What could be the reason here. We have flashed asset tracker hex file for initial testing. 

Need to know root cause of this issue and looking for support from Nordic here. 

Thanks,

Hello,

One potential issue could be SIM voltage. Which SIM card and what is the supported voltage of the SIM you are trying with? Please see that nRF9160 supports only 1.8v SIM cards. Have you tried changing the SIM card to make sure it's not an issue with the SIM card?

Is there any message from the log that describes the issue?

Kind Regards,
