Hello, previously I used the I-CUBE-LRWAN LoRa v1.2.0 with region AS923 no prob it can join and send data. I dropped in the newer v1.3.1 I-CUBE-LRWAN LoRa with same compile define/same region etc... it cannot join the LORA network (same APPKEY/same DEUI etc...).
I can see with debug level 2 that the transmit frequencies are good (923.2/923.4Mhz for Join command), but I cannot get any JOINED return (join success) and the MCU is stuck there. Please anyone had the same issue, any suggestions?
