Hi @rmackay9, I have had a win!
I went and rewired the whole setup I have from the sounder to the Pixhawk. Installed some new quick connects, etc. I followed the wiring setup as specified in the ArduRover documentation.
Doing it this way I got no data in MP. I switched the TX and RX between the RS232 to TTL Converter and the Pixhawk. I then got data in MP but only when I connected to the unit via Bluetooth to the PC. Stop the Bluetooth and then no data.
So I switched the TX and RX wires from the Unit to the RS232 to TTL Converter and Viola!
So I am unsure if the Converter I got already does the switching internally? But I am getting the data through MP via RS232 and correct values.
I can’t wait to install this into the Boat and get the RTK Logging with the Depth. This saves me about 1-2kg of Weight that I don’t need anymore.
Great job with the NMEA Driver. If you like I can draw up a wiring diagram of my setup so you could add this onto the list of supported depth sonars/sounders?
Thanks, Scott. (P.S. Donation coming to ArduPilot in the coming days for the Software in the Public Interest, Inc.)
