No Telemetry with SpeedyBee F405 wing App and Speedybee F405 wing

ArduPlane Plane 4.5

Hello folks.
I hope you are enjoying these days of the season.
I’m kind of new to FPV and I need an urgent help please.
I have a Speedybee F405 Wing App flight controller and Speedybee F405 Wing. Both flashed with the latest Ardupilo for mission planner.
The Speedybee Wing App would connect through the F.Port and I get servo response but no telemetry. I tried the S.Bus and the S.Port and it is the same thing, servos respond but no telemetry. I used UART 2 TX and the Un-inverted port on the Frsky R-XSR receiver. I tried UART 4 but nothing changed. I looked up Ardupilot site and followed the setup instructions including getting an external inverter (TTL to RS232). No luck.
As for the Speedybee F405 Wing, it connects immediately without any thing, and the Yaapu telemetry work using the un-inverted F.Port with full servos response. But the problem is that it works for less than a minute and then it freezes. no telemetry and no servo response.
I tried Half duplex, Inverted TX, TX pull up. RSSI setting. Still, No GPS telemetry on my X20S
I’m I missing anything here?

If anyone can help me out, I would appreciate it.
A quick note.: The same setup works great with no issues using Matek 2.4 ELRS receiver
The set up is:
FrSky X20S radio with Yaapu 1.4.0 for Ethos.
FrSky R-XSR receiver with the un-inverted F.Port/S.Port.
I also added TTL to RS232 inverter and used it with the Inverted F.Port/S.Port.

Thank you all in advance and have a great holidays

Connect uninverted F.Port with UART1 TX and set SERIAL1_PROTOCOL=23 and SERIAL1_OPTIONS = 20.

Hello.
Thank you for your reply.
I just tried that. It didn’t work. This is on the Speedybee F405 Wing App.
I did manage to make the Speedybee F405 Wing mini to work. I connected the S.Bus and the uninverted S.Port on UART 2 and set the SERIAL2_OPTIONS = 132 and SERIAL2_PROTOCOL= 10!! which came as a surprise to me. S.Port pass through of open Tx!!
but it is working fine.
The same setting didn’t work for the F405 Wing App.

You cannot use the Wing app for Ardupilot.

You want to use F.Port, see my quote, and that works as described.

I will try that.
Thanks, and happy holidays
