Hello!
I want to connect Leica RTK GPS (Leica SmartAntenna + Leica RX1250 controller) to LOWRANCE LMS-525 C DF via NMEA 0183. The reason for that is I want to get precise (centimeter level) position of sonar readings. Unfortunately there is some problem and I cannot diagnose it. I sticked to the manual when connecting everything, but without success. In the opposite direction (transmitting position of sonar from standard Lowrance GPS) NMEA 0183 works fine and I can read GGA message on PC (via Parani bluetooth serial adapters and then in Python script).
This is the NMEA GGA message received from Leica GPS:
b'$GPGGA,203748.40,4925.8006561,N,02016.5010872,E,1,05,4.0,653.042,M,,,,*3C\r\n'
And this is the NMEA GGA message received from standard Lowrance GPS:
b'$GPGGA,203557,4925.8007,N,02016.5573,E,1,3,4.41,-41,M,,,,*17\r\n'
So they only differ in position decimal precision. I’ve also tried to transmit this Lowrance GPS NMEA GGA back to the sonar – without succes :/
I’ve tried to show everything on the video:
Here are also some useful pictures: LOWRANCE – Google Drive
Link to Sonar manual found on the internet: https://www.gpscentral.ca/manuals/LMS525CDF-520C_0151-461_120706.pdf
I will be very grateful for any suggestion and help!
Thank you!
