Problème drone LR4 et CrossFire (pas de communication)

[valkarnea]

Je rencontre de grosses difficultés à établir la communication entre mon drone et le RX, et ça me rend complètement fou. Ça fait deux jours que j'essaie de résoudre ce problème, et je serais vraiment reconnaissant pour toute aide ou conseil. Voici un résumé de tout ce que j'ai fait jusqu'à présent :

Fichier CLI complet si dessous (commande diff)

Configuration :
Drone LR4 O3 PNP
TBS Crossfire Nano RX
Tango II

Câblage du Nano RX :
TX connecté au RX sur la fc
RX connecté au TX sur fc
Connexions 5V et GND sur la Goku F405.

Configuration dans BetaFlight :
Activation du Serial RX sur l’UART 4 (récemment soudé).
Protocole du récepteur configuré sur CRSF dans l'onglet Récepteur.

Problème rencontré :
Aucune entrée détectée du récepteur dans BetaFlight.

Tentatives:
Mise à jour de la Tango II et du Nano RX plusieurs fois avec le dernier firmware
Mise à jour de la FC vers BetaFlight 4.5.
Communication confirmée entre le Tango II et le Nano RX.
Déconnexion des connexions RX et TX de l’UART 6 du O3, mais non... c’était le fichu GPS.
Testé sur un autre drone équipé de Crossfire et ça fonctionne bien.

Problème actuel :
Aucune communication entre la carte de vol (FC) et le Nano RX.
Je ne comprends pas pourquoi il n’y a aucune entrée malgré la configuration

Est-ce que l'O3 pourrait empêcher le fonctionnement du récepteur Crossfire, même s'il n'est pas configuré comme Serial RX ?
