[CLOSED] No activity and data in signal K for USB/NMEA but logfiles get them - Phil - 2020-08-11
Hi,
I have connected my nmea 0183 loch datas: depth, wtaer temp, ... and logfile is ok for my device:
1597175775146;N;$VWVHW,,,,,00.0,N,00.0,K
1597175775146;N;$PTTKV,00.0,A,00.0,03339.0,00882.7,28.1,C
1597175775147;N;$PTTKD,003.8,A,B
1597175775147;N;$VWVLW,03339.0,N,00882.7,N
1597175775148;N;$VWMTW,28.1,C
1597175775148;N;$SDDPT,003.8,+0.0
1597175775312;N;$SDDBT,012.8,f,003.8,M,002.1,F
But nothing in signal K web app (dashboard, databrowser, ...).
For my wind data, everything works fine: log files and dash board and databrowser,...).
Bug ?
Thanks in advance for your help (last version of openplotter installed with signal K 1.26)
Best regards
Philippe

Your logfile messages don't have checksums, they should look like this >
$VWVHW,,,,,00.0,N,00.0,K*4D
If you can't get the devices to send with a checksum then in the signalk connection set validate checksum to no and append checksum to yes. Though not all messages are decoded into signalk

Hi, great, you were right, removing the checksum check now it works!
Thanks a lot :-)
Perhaps write few words in the doc about this behavior...
