Ethernet over serial via PPP on H743

Hi,
I am trying to get PPP working on a mateksys H743-WLTE with a UART to Eth adapter. I used the custom firmware tool to build with ppp network enabled. I have also added the net_webserver lua script. However I cannot ping the autopilot on 192.168.0.14 (static ip set on my computer and the adapter). I have the adapter powered by 3.3v , with autopilot RX/TX 7 connected (SERIAL1) to the TX/RX on the adapter. And get the network lights showing activity (can use the tool to get data sent/received).

I am unsure where to debug next on what may be set incorect or why i wouldnt be able to ping the autopilot? My goal is to connect over mission planner to the autopilot via ethernet (either UDP/TCP).

That device doesn’t look like it supports PPP? If we wanted to support it we’d need to add a new AP_Networking backend with a driver for this device.
Also note the max baud of 460kbaud is actually v slow compared to what we will be able to do with some serial → ethernet devices that will be out soon from BotBlox and CubePilot. Those will do 12.5Mbps (so 36x faster)

ah no wonder! Thanks. serves me right for using something lying about haha will get one of thoes once they are out.
