I found a thread with someone using the RX1 (non-inverted) port with an f405 wing using serial_option 4, and matek’s website shows settings for the CTR using serial_option 7. I have the latest non-access firmware on my r9m and r9 slim+. I cannot get any telemetry working using either serial option(4 or 7) on the RX1 pin, or the normal S.Port pin. I was doing a full reboot between each option change, pulling USB and battery. I thought it might just be out of date firmware but someone replied in June 19 saying it worked and there was no Access firmware then for this receiver. Every once in a while when I did discover new sensor I would get a GPS field to pop up, but if I deleted and tried again it usually wouldn’t come back. I also tried frsky s.port instead of passthrough and still nothing.
Any ideas?
I’m using the TX4 pad which should be Serial2 in arduplane.
