Hi @vladi,

Maybe you can try to use our latest firmware for RAK8212(M)。
In our latest firmware of RAK8212(M), we supply a method to send AT command to RAK8212 or BG96 from Nordic mobile APP over BLE.
The latest firmware is here:
https://downloads.rakwireless.com/en/Cellular/RAK8212/Firmware/
the document is here:
https://downloads.rakwireless.com/en/Cellular/RAK8212/Application-Notes/

Hi,
I have test the firmware. It is ok. According to your log, I think your cmd is not right because it is just a unvarnished transmission. After download, the red led will blink which means bg96 is working. Has your board started normally? Check battery supply. Below is my log:
