📡 ACCST / ACCESS (FrSky)
FrSky\x27s two families of 2.4 GHz control protocols — ACCST is the older one, ACCESS the newer.
ACCST exists in an older V1 and a newer V2 that are not compatible with each other, which trips up a lot of people mixing older receivers with newer radios. Match the firmware family across transmitter and receiver before you try to bind.
