Telemetry enabled protocol:
- by defaut using FrSky Hub protocol (for example er9x): RX(A1), battery voltage FS-CVT01(A2) and RX&TX RSSI
- if using erskyTX and OpenTX: full telemetry information available
- if telemetry is incomplete (missing RX RSSI for example), it means that you have to upgrade your RX firmware to version 1.6 or later. You can do it from an original Flysky TX or using a STLink like explained in [this tutorial](https://www.rcgroups.com/forums/showthread.php?2677694-How-to-upgrade-Flysky-Turnigy-iA6B-RX-to-firmware-1-6-with-a-ST-Link).
Option is used to change the servo refresh rate. A value of 0 gives 50Hz (min), 70 gives 400Hz (max). Specific refresh rate value can be calculated like this option=(refresh_rate-50)/5.
**RX_Num is used to give a number a given RX. You must use a different RX_Num per RX. A maximum of 64 AFHDS2A RXs are supported.**
OpenTX suggested RSSI alarm threshold settings (Telemetry tab): Low=15, Critical=12.
