Cannot connect RAK811 to TTN
I'm unable to connect to a RAK811 WisNode to the Things Network using either OTAA or ABP. Every time I try an OTAA join command I receive at+recv=6,0,0. Node and gateway are 915MHz; node is set to DR:8 and freq 923.3, mode is set to 0, and I've verified that the app eui and app key are correct. Any ideas?
