I am trying to get OTAA to work on the Nexus board with the sketch provided by Ideetron, but it doesn't seem to work. I got ABP working with this software so the board itself is working fine, but for OTAA I have no luck yet.
I have set up DevEUI, AppEUI and APPKey properly, and I checked the proper settings for chtx, drtx, chrx, drrx as they recommend in their manual, but when I give the mac join command, it just says 'timeout' after a few seconds without any other debug information. I tried both on Semtech and on the KPN netwerk with same result. I hooked up my logic analyzer to the SPI interface and see plenty of data going back and forth to the RFM95 when I give the join command, but it's quite a job to reverse-engineer from that what is going on.....
Does anyone have any experience with this sketch on this board and got OTAA working?
