Frsky OpenTx Integration, Basic Telemetry
I am using the OpenTx integration on my gasser helicopter, I selected the basic telemetry in the throttle menu, and I searched for new sensors on my TX, I am now receiving telemetry for RPM, Global Vibration but not for servo voltage, how can I solve the problem of the servo voltage value not being transmitted by telemetry.
With OpenTX and FrSky receivers, all transmitting the RxBt value, this is normal.
The receivers are powered together with the servos, being connected to the servo bus of the Brain2 controllers they share the same supply voltage.
Therefore the supply voltage of the receivers is identical to the supply voltage of the servos and it would be useless to occupy the telemetry bus by transmitting two identical values.
The servo bus voltage (which is also the receiver supply voltage) is only transmitted when using telemetry receivers that do not transmit their own supply voltage (Spektrum SPM4649T receivers come to mind).
