Dear Jason:
I have the same question.
======== As you mentioned =============
AT+RXO=2
AT+SD
< << RECEIVE DATA and Parity >>>
< << RESPOND WITH CRC >>>
=====================
I already let xDot in serial mode, and received something.
it seems a setup packet with encryption, how can I decrpt it??
And how can I respond CRC ok with encrption?
