I know I am a bit over my head here but just wanted to get some input and some direction from those who will know more about this than I. I have a Pixhawk, it has Serial4/5 port open and I was curious if it was possible to send data through this serial port and pass it through the siK radio’s? The data is from a sonar/fish finder that has a 5v TTL signal, that I would convert down to 3.3v with a logic level converter, like this one:
The NMEA 0183 output from the sonar is at 4800baud (from what I have read) and the following sentences are outputted:
DPT - depth
MTW - water temperature
GLL - Lat/Lon Position
GGA - GPS Fix Data
RMC - Recommended Minimum Specific GNSS Data
VTG - Course Over Ground and Ground Speed
ZDA - Time and Date
Now could this serial data be be fed through the Serial 4 port and sent through the siK radio? I have other ways of trying to send this data, but this would be the cleanest and most energy efficient way to do this.
