Today I discovered that, the Rx needs to be pulled HIGH and the AUX needs to be pull LOW.
I use a 4k7 between +5v and RX, and an LED between Aux and Gnd.

Use EBYTE's own Accessport, Channel means freq. ie channel 12 for me was 912Mhz, not the International recognised channel 12. Type in text, but go back to HEX before you send. Don't for get to tie down M0 and M1 to ground. Enjoy
