Mavlink to FrSky S.Port Passthru Converter for LRS or PX4 Pro

Hi Eric! I’m attempting to use your converter with Dragonlink in a relay setup using a 2.4GHz FrSky receiver. I would like to have mavlink via UDP to a GSC running on a PC, and telemetry over the 2.4GHz link into my radio for Yaapu. I have the Heltec ESP32.

Initially I used Noircogi’s pre-compiled version of firmware from this guide: https://docs.google.com/document/d/1ePGAmYa-GSwJ9TrpRcMSZ5HjKpIELJfxtvpISxID2Xs/edit?usp=sharing Using that, I have mavlink on the LAN via UDP working just fine. I built an inverter for s.port according to this: Some soldering required If I connect the s.port wire to the FrSky receiver, the ESP32 reboots endlessly in a loop. If I unplug the wire from the receiver, but leave the inverter attached to the ESP32, it starts and and operates as expected.

Last night I compiled " v2.6602d", the latest on github. I no longer have the boot loop issue with s.port connected, but I’m not getting anything over UDP, GCS will not connect. (I tried QGC and MP) I also have no data into the radio over the 2.4GHz link. The display on the Heltec board shoes “Mavlink Good!” and starts showing the RSSI and some altitude data, so I assume mavlink data is making it that far.

Could you maybe give me a quick list of options I need to set in config.h and/or in the web GUI to get it working to rule out user error before I dig any deeper to get this working?

Thanks in advance for your help!
