Hi @JayjJay ,
I am sorry to miss to reply on this. I suspect that the SN wasn’t written. There is a special AT command that can write SN but we do not share it in public.
It shows as well that you are using v1.0.4, I suggest you update the firmware to RUI3.
Hi @rami ,
I just replied on your issue on your own forum topic
