Telemetry enabled for A0, A1, RSSI, TX_RSSI, TX_LQI and Hub. Lower TX_LQI indicates a better quality link and is a good indicator of how well the module is tuned.

In OpenTX the FrSky D protocol is accessed as FrSky, with subprotocol D8.

The FrSky protocol also has subprotocols for FrSky V receivers, FrSky X (D16) receivers in FCC and EU/LBT modes and D16 receivers operating in 8 channel mode.
