Send GPS data from OpenPlotter to Tinypilot

[MarineW29]

Hi Sean,
Sorry for my late response.
GPS data comes from a "Neo-6M" GPS connected via UART5. I configured it in OpenPlotter "Serial" application to send data to Signal K.
Here is an excerpt of GPS data from Signal K Data Brower for the data you mentioned :

Path                                 Value                Units  Timestamp       Source
navigation.speedOverGround           0.13194444444444445  m/s    02/15 13:32:25  gpsneo6m.GP  (VTG)
navigation.courseOverGroundTrue      null                 rad    02/15 13:33:03  gpsneo6m.GP  (VTG)

We can see that "navigation.courseOverGroundTrue" have a null value.


Here is an excerpt of the pypilot execution logs with debugging enabled:

signalk zeroconf service add avnav-server._http._tcp.local. _http._tcp.local.

Exception converting signalk->pypilot unsupported operand type(s) for /: 'NoneType' and 'float' {'GP': {'navigation.position': {'longitude': -4.000000000000000, 'latitude': 47.0000000}, 'navigation.courseOverGroundTrue': None, 'navigation.speedOverGround': 0.1193511413467336}}

For security reasons, I replaced the decimal digits with zero in the longitude and latitude values  

It looks like pypilot is in having issues with this "None" value for "navigation.courseOverGroundTrue".
Maybe because I'm testing from home, without moving ?
