FrSky remote controls

FrSky

— a proprietary protocol from FrSky Electronic, used in its radio control systems. Reliable communication is ensured over short and medium distances with low latency in data exchange between the controller and the receiver. At the same time, the ability to transmit telemetry has been implemented. There are several varieties of FrSky protocols, in particular, D8 and D16 (named for the number of supported channels), as well as the more modern FrSky ACCESS standard.
