Send GPS data from OpenPlotter to Tinypilot

[MarineW29]

Hi,

I'm trying to send data such as GPS from OpenPlotter to Tinypilot, but I'm having trouble.

Configuration :

- Raspberry Pi 4 with OpenPlotter
    - SignalK server with mdns option enabled
    - GPS (Neo-6M) connected via UART5 => data arrives in Signal K
    - OpenCPN with Pypilot plugin => the plugin shows "Connected to pypilot"

- Raspberry Pi Zero > with Tinypilot / Pypilot version 0.32 (tinypilot_2021_11_16 image)

Tinypilot is connected as a client to OpenPlotter AccessPoint.
NB : At the moment, I am at home, without pypilot hat or motor controller.

I successfully connected Pypilot to SignalK, using the "zero configuration" method.

In the SignalK Data Browser, I can see navigation.headingMagnetic and navigation.attitude from the pypilot source, navigation.position (with correct longitude/latitude) and other informations from the GPS source.

OpenCPN is connected to SignalK (via the SignalK protocol on port 3000) and shows a good GPS reception.

I would like to check if Pypilot can get informations such as GPS location from OpenPlotter. I saw the "gps.source" information in the OpenCPN pypilot plugin, in the Stats window.
==> Is there another way to verify this information (and other verification statuses) ? I don't see it on the "Pypilot control" web page for example.

I read in the workbook that Signal K can only get data from Pypilot, but cannot send data to Pypilot.
==> Is it right ? Or is this information out of date for the version I'm using ?

The "gps.source" of the OpenCPN plugin shows "none", and I can't choose the "gps" autopilot mode. In fact, I just noticed that it rarely and furtively displays "signalk", but most of the time it displays "none".
==> This does'nt seem normal, does it ? What could be the reason?

I've tried sending NMEA0183 data from Signal K to Pypilot, but I can't figure out what the correct configuration is. I tried the following things :
1 - put "openplotter:10110" on "Pypilot control" webpage > Configuration > NMEA Client host:port (no "save" button ?)
2 - on SignalK > Data Connections > Add a NMEA0183 connection :
    - Source : TCP client
    - Host : pypilot
    - Port : 20220
    - Output Events : nmea0183,nmea0183out              => I didn't really understand the doc about this
3 - on SignalK > Data Connections > Add a NMEA0183 connection :
    - Source : TCP server on port 10110

None of them seemed to do anything :
-  "gps.source" was still "none"
- I could'n see the network connections between OpenPlotter and Tinypilot on port 10110 or 20220 :
    - On Tinypilot :

Code:

tc@pypilot:~$ netstat -apn | grep -e 3000 -e 20220 -e 10110

==> What is the correct configuration to send NMEA0183 data from Signal K to Pypilot ?

Thanks for your help !
