EVK-R410M Communication settings

I am having trouble communicating with my EVK-R410M board since updating the FW.

The comm ports are present, but I can only send AT commands maybe 1 in 30 times.

I have tried the default settings, plus the ones that work OK with my SARA-N211.

Does anybody have any known working settings I could try

Thanks in advance

Hi @dustewar,

You can try to send the AT+CFUN=15 commands to remove the saved profile.
This usually works better when you first remove the sim card.

Best regards,

Communication is now working OK.
But registration with Vodafone NW is not.
Vodafone IoT SIM card is working OK with SARA-N211, but will not register with R410M.

Seems all the settings are correct, but any ideas welcome.

Also any AT+URAT commands returns an error "+CME ERROR: Operation not supported)


I have updated the AT commands an hour ago.
The new R410M firmware requires you to set a mno profile.

Please have a look at the commands:

Best regards,
