Hi @drone4ya_z

Please try to send AT+QNWINFO and AT+QENG=servingcell" command when doing network searching.

Can you provide IMEI? The firmware version you provided was not found in our database; If the search time of your module is not enough, I suggest you extend the search time and try again

AT+QNWINFO
+QNWINFO: “eMTC”,“310410”,“LTE BAND 12”,5110

As for AT+QENG=“servingcell” what will be the servingcell value

I think I figured it out, while doing at commands I have to attach to network every time I reboot hence I was not getting the IP address.

Interestingly when using the REPl and python net api calls, I can always get the ip address after reboot , not sure why

Here is my article
