I am using STM32L152RET6 running I-CUBE-LRWAN V1.2.1 CLASS A. I am pushing data to TTN and I can perfectly see the uplinks and downlinks from my LoRaWAN Gateway (RHF0M301):
JSON up: {"rxpk":[{"tmst":56541636,"chan":2,"rfch":0,"freq":915.500000,"stat":1,"modu":"LORA","datr":"SF10BW125","codr":"4/5","lsnr":8.8,"rssi":-4,"size":24,"data":"gEQRBCaADwAC9YCH9Gb6EIRJKmpnRAAU"}]}
INFO: [down] PULL_RESP received - token[119:61] :)
JSON down: {"txpk":{"imme":false,"tmst":58541636,"freq":923.2,"rfch":0,"powe":14,"modu":"LORA","datr":"SF10BW125","codr":"4/5","ipol":true,"size":22,"ncrc":true,"data":"oEQRBCalKAADUP8AAQJDkWszrPMYxw=="}}
The issue I'm facing is that I cannot receive this downlink on my device. This is what I can see from the VCOM terminal:
TX on freq 915500000 Hz at DR 0
793s381: PHY txDone
RX on freq 923200000 Hz at DR 10
797s363: PHY rxTimeOut
797s901: APP> McpsConfirm STATUS: Rx 1 timeout
797s901: #= U/L FRAME 20 =# Class A, Port 2, data size 11, pwr 0, Channel Mask FFFF FFFF FFFF FFFF 00FF
I have tried changing data rates from 0 - 13 and nothing works. Been stuck here for quite a while now appreciate if anyone here can push me in the right direction. Many thanks in advance.
