Hello,
I am facing below AT_cmd errors after flashing my application to nRF9160 DK. Please support me how to resolve these errors asap as its blocking our product development activity.
I want to setup the MAGPIO in the main function before calling the LwM2M carrier events. But looks like AT is not getting initialized unless and until DK board is not connected with LTE via LwM2M carrier. If I send same AT command after LTE connected to network then the AT command will work and will not throw any errors which is more confusing to me.
Errors:
<err> at_cmd: Failed to open AT socket (err:-117)
<err> at_cmd: Failed to send AT command (err:9)
Reference code: (Note: This is just a reference code where I just want to share that how exactly I am want to setup the MAGPIO in main() )
