Is anyone doing this? I use DOSD for my on-screen display and I want to share the GPS strings between the two devices. I know with DOSD I can use pass-through mode and it will send the NMEA strings over the serial port, but with my APM connected to DOSD i don't see anything. I have my DOSD serial port connected to soldered pins on the APM board GPS Port (Tx,Rx, GND).
I am wondering if I can pass the GPS strings from APM to DOSD GPS port instead.
