RAK4600 ATcommand missing

I received my RAK4600 module (not eval kit). It works but I can’t change the datarate from DR3(factory configured) to DR0 with the command at+set_config=lora:dr:0 It shows an error. In fact when I print the list of all atcommands available (at+help) it doesn’t appear in it. The firmware is v3.0.0.8 and according to datasheet and other documentation, like Quick guide for AT commands of RAK products, the command should be available. Why is it not the case? Do I have to reupload a custom firmware? Thanks for your help.

Hi, @jettt,
In the near future, there will be a unified firmware upgrade, adding more protocol stack configuration instructions. Later, you can get the updated firmware from below.
