==== Télémétrie ====

Le SmartPort du R-XSR est branché sur l'UART 1 de la FC. Mais le contrôleur F4 n'a pas d'entrée "inversée" permettant de traiter le signal inversé, le signal doit donc être inversé de manière logicielle.

Pour cela on assigne le pin voulu au softserial 1 :

  resource SERIAL_TX 11 A09
  save

Dans Betaflight on active le softserial dans la page configuration : 

{{:softserial.png?direct&400|}}

Dans la page Port, on active le smartport sur le nouveau port "Softserial 1" qui vient d'apparaitre :

==== Motor Beacon ====

Activation des bips moteurs (parce que le beeper s'est barré de la carte avec son pad), dans la page configuration, dans la section **Dshot Beacon Configuration**, sélectionner un "**Beacon tone**" et activer "**Rx_set**" pour activer les bips lorsque l'inter affecté au beeper est activé.
