[SOLVED] NMEA 0183 generator losing data.. - PaddyB - 2017-09-13
Hi, on this setup -
Pi3, openplotter 0.15.1, ads1115, BMP180, MPU9250, dual usb serial ais/gps
I have the generator set to create a MDA nmea sentence from the BMP180 barometer data and some other sentences -
[NMEA0183]
sentences = [['MTW', [['propulsion.eng.temperature', 'x.x', '-', 273.15], 'C'], 1.0], ['MDA', ['', '', ['environment.outside.pressure', 'x.xxx', '/', 100000.0], '', ['environment.inside.temperature', 'x.x', '-', 271.15], 'C', '', '', '', '', '', '', '', '', '', '', '', '', '', ''], 1.0], ['HDG', [['navigation.headingMagnetic', 'x.x|deg', '+', 0.0], '0', 'W', '0', 'W'], 1.0]]
Problem is it seems to lose the barometer data after a few minutes. If I edit the generator, or just go in and OK again, this sentence is created -
$OCMDA,,,1.021,,26.8,C,,,,,,,,,,,,,,*39
Then after a few minutes it doesn't add the pressure ..
$OCMDA,,,0.0,,27.0,C,,,,,,,,,,,,,,*32
Nothing showing up in the terminal just this after restarting the NMEA generator..
GET /signalk/v1/api/vessels 200 4.067 ms - 5358
The signalK side seems to be fine, it gets saved to a database an doesn't show any dropout of the barometer data.
Odd one, any ideas anyone?
TIA

I will try to reproduce, thanks

I am not able to reproduce this issue. I always have pressure data.
Have you discarded bad connection or hardware malfunction?

I can't reproduce it either now
That's without even a reboot.
I'll keep hunting and logging, pretty sure hardware is fine, the database get stored from signalk data and it seems to be fine all the way, no zero values.

Do you mind if I mark this as solved? We need to clean the list to go forward
reopen if necessary.

I think that's probably the best way to go so you can move on, it's still dropping out but will run for hours and I can't track down why so think I'll give up for now, it isn't vital anyway. If anything new comes up I'll post here.
Thanks
