nmea output not working on usb-serial
#1
Hi there,

I have an rs422-usb converter connected to the usb port of the tinypilot. The converter is connected to nmea 0183 connections (in and out) of my instruments. It is receiving wind data (and various other sentences) successfully and repeating them to TCP.

Unfortunately the NMEA output is not working. The tx light on the rs422 converter never lights up. I would like to output at least rudder angle RSA and compass HDM so that they can be shown on my instruments.

The tinypilot does output these sentences on TCP over wi-fi but not on the usb serial connector. It is recognising the usb serial connector and using it as an input for wind data (the "W" appears on the tinypilot screen), just no output.

Is this a missing feature or is there something I can do to turn it on or fix it? A working rudder instrument is especially important for us and I have to keep reverting to our old autopilot (which has working nmea output) to get  a rudder position display. It needs to avoid repeating back any sentences which were received from the instruments as that would cause a feedback loop.

It should ignore any rudder position coming back from the instruments as that will be an echo of what it sent. The position coming from the servo should take priority. Same with heading - internal sensor value should replace the received nmea value.

Thanks!
