I’ve tried to perform a Network Survey using the AT#CSURV command on a LE920-EUG Module.
I’ve tried with and without a inserted SIM Card and for different Bands, but the result is always the same:
+CME ERROR: unknown
Has anyone an idea how to solve this?
The ‘at#csurv’ command was added on the 17.00.103 FW version.
Can you please advise which FW version you are using?
You can check the FW version by issuing the ‘at+gmr’ at command.
You can see below an example of running the ‘at#csurv’ command on LE920-EUG module with 17.00.103 FW version.

Thanks for your help. I’m still working with the 17.00.102 Firmware, so now I know where the Problem is. I’m going to contact the support for access to the current firmware.
