I’m currently facing an issue while configuring the IN865 frequency band on my RAK3172 module. When I attempt to set the band using the AT command:
AT+BAND=3
I receive the following error:
AT_PARAM_ERROR
Interestingly, this setup worked perfectly with my previous RAK3172 module. It seems the current firmware might not have the IN865 region enabled or supported.
Could you please advise on how to resolve this? Specifically:
Looking forward to your support.
I also flashed the latest (RAK3172-E_latest_final.hex)firmware via STM Cude programmer still facing the same issue is there any help you guys can provide
What RUI3 version are you using?
Is the module set to LoRaWAN mode?
Are your AT commands ending with CR LF?
Works fine for me:
Please send the following commands and share the response here:
AT+VER=?
AT+NWM=?
I am getting this ouput
at+ver=?
AT+VER=RUI_4.0.6_RAK3172-E
OK
at+band=?
AT+BAND=1
OK
at+nwm=?
AT+NWM=1
OK
at+band=3
AT_PARAM_ERROR
Make sure the device didn’t try to join the network with AT+JOIN=0:0, then restart and try again.

Another thing, are you using the default AT command firmware or are you using a custom firmware built with the RUI3 API?
If it is a custom firmware, please make sure you have enabled IN865 when you compile the firmware.
