Let us know. Im not familiar with the NewChannelReq and how it works, but I've been diving deep in the Loramac stack for the adaptive datarate over the past few days, so i'll take a look here as well.

So this should do it, acknowledging that no channel willever use AS923 data rate 0 or 1? for channel in range(0, 15): lora.remove_channel(channel) lora.add_channel(0, frequency=923200000, dr_min=0, dr_max=3) lora.add_channel(1, frequency=923400000, dr_min=0, dr_max=3) lora.add_channel(2, frequency=922200000, dr_min=0, dr_max=3) lora.add_channel(3, frequency=922400000, dr_min=0, dr_max=3) lora.add_channel(4, frequency=922600000, dr_min=0, dr_max=3) lora.add_channel(5, frequency=922800000, dr_min=0, dr_max=3) lora.add_channel(6, frequency=922000000, dr_min=0, dr_max=3)
