Quectel BG95-M9 failing network registration

[d.grimm]

So im trying to get the BG95-M9 to work with the EVB but when im using the automatic initialization i get the following error msg

We would really like to use Quectel for our future applications but unfortunaly we are new to this market and therefore unfamiliar with the technology or what could cause this problem.

Kind regards,

I suggest you add a AT command and execute them multiple times

AT+QENG=“servingcell”
AT+CGPADDR

Even after multiple repetitions the result of these to commands is as follows:

By providing the Log, BG95 has successfully registered with the network and successfully obtained the IP, you can test QPING

Thank you i will try that as soon as possible but i have another question
Does the BG-M9 Chip support 450MHz like the M4?
Because as you can see it is absent in this picture

You can check the hardware manual for instructions
