I see that the air unit has telemetry at 57600 baud and potentially can work at 115200. Whats the feasibility of creating a creating a PPP to Serial driver on the air unit? Would need some hardware mod to get hardware flow control.
I also see adb has some PPP argument and potentially a usb-serial adapter could be used.
The cubenode eth beats botblox in price however microhard has serial-udp and also a ppp driver built in, It would be nice to replicate that with the herelink.
