Issue: I seem to be unable to set SF6 on a RAK811. It returns an Error 2 (argument not found). The hardware supports it, the documentation for the RAK811 suggests it is supported both through AT commands and the API however it always returns an error.
Setup: I am using a WisNode RAK811 Development board, version V22.214.171.124.H.T3.
Details: I successfully change to LoRaP2P mode and can set the SF to any other value [7-12] and have tried all combinations of BW and CR in case there is any restrictions on certain configurations. The command I am using is at+set_config=lorap2p:868100000:6:1:1:5:10.
Can anyone confirm if they have been successful in configuring SF6 and if so how? Does anyone know what the problem might be?
