I-CUBE-LRWAN LoRa v1.3.1 region AS923 cannot join LORA gateway while v1.2.0 can join

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?

Apparently the command AT+DEUI=*** is not taken into account in the v1.3.1, it must be set at compile time.
