Telemetry supported with A1=battery voltage (you need to adjust the offset with a voltmeter since there are some large differences between the models), RX_RSSI = TQly = percentage of received telemetry packets which has nothing to do with well the RX is receiving the TX but instead how well the TX=multi module is receiving the RX.

Telemetry is using the NRF24L01 RF component @250K so depending on your module it might not work well.
Option for this protocol corresponds to fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable.
