Hi. One of the units I recently purchased for prototyping immediately fails when I try to do an OTAA join. The same code works okay on other units.
I am thinking there is a hardware fault or maybe I got sent a 433MHz unit rather than a 915MHz one by mistake? Is there any way to check? Thanks again.
