Hi there, I am still stuck in a similar issue. I am not able to get mavlink osd data on my H16 of the Siyi Zt30 Camera. The FC is connected with the AU and Siyi Camera with Uart, everything is configured according to the documentation but no data on the Siyi Fpv App yet.
H16 needs to use the same network segment as ZR10 or ZT30, such as 192.168.144.xxx. Do not run siyi fpv but use qgc. The complete compatibility of siyi’s products is limited to its own supply chain.
I am facing issues of video lag in QGC and also no features of LRF data or temperature data or any other features that are in siyi FPV app are not compatible with the QGC.
