No signal k stream with serial port provider

[manu f]

Hello all,

I open this new tread to be more relevant from my problem.
In a previous tread Teppo explain me how to setting signal k to get data from serial port.
So I modify the /settings/volare-serial-settings.json file with my serial device (ttyUSB2)

I already test my server with mnea from file and different consumer, all working nicely.
I know that my pi can get nmea string from this device cause I opened this port it with picocom -b 9600 /dev/ttyUSB2 and saw my nmea stream.

So when I launch the signal k, like that bin/signalk-server -s settings/volare-serial-settings.json
I have this console output:

No settings/defaults.json available

signalk-server running at 0.0.0.0:3000

I know my port is open by the provider because I see the rx led activity flash on my serial to usb converter (this append only if the port is open)

The I try to launch some demo consumer, like simple gauge or instrument panel, but gauge not move, so I think I have signal K stream (I will confirm this by looking to the socket)....

:-(

I must add, if its could help that I had a problem on the pi when installing the signalk node js server with the serialport component, I found the soluce here : https://groups.google.com/forum/#!searchin/signalk/serialport%7Csort:relevance/signalk/ZNbHsqgKofc/587c8KhYBwAJ

Now What can I do to find where is the problem? is there some log somewher useful? or could I set logging ?

Thanks for your help,

Regards

Have you changed the data rate in volare settings file to match your 9600?

Try adding a line that says

console.log(chunk)

at https://github.com/SignalK/signalk-server-node/blob/master/providers/serialport.js#L73

that should log everything comin from the serial port.
