Read Serial 4/5 from Pixhawk in Mission Planner

Posted by Esteban Caligaris on July 22, 2016 at 8:27am

Hello everybody,

I'm attempting to use the Serial 4/5 Port of Pixhawk to connect to it a device that outputs NMEA sentences, but is not a GPS, is a Garmin Sonar.

I want to know if there is a way to read these sentences in Mission Planner in real time.

Is there a way to read messages, in real time in Mission Planner, from other devices with the Tx and Rx Pins provided in the Serial 4/5 Port?

Regards,

Esteban Caligaris

    Hi Esteban,

    Did you eventually solve this issue? I am currently attempting to accomplish the same thing. I am using a sonar which outputs NMEA 0183 and I am thinking of bringing the messages into an arduino to filter out everything I dont need, and then send the relevant information to the pixhawk through Serial 4/5, at which point the pixhawk will transmit the data through the telemetry radio.

    Once this starting point is accomplished, I will be looking into creating an ethernet bridge to transmit the full NMEA string.
