I get very similar stuff to yvereg in Signal K - number of sats shows 10, Date/Time is correct and messages are current but Lat/Long is null, as is COG and Mag. var.
I am using a USB Globslsat BU-353
That is not what yvereg is reporting as a problem as far as I am aware from reading his posts, the screenshots in the thread where lat/long, COG and Mag var are showing as null are mine not his. That's because the USB GPS module is sitting on my desk with no view of the sky.
His problem is that he can't successfully install his GPS so isn't getting any messages in Signal K at all, null or otherwise. The problem is as he reports "no such file or directory cannot open /dev/ttyOP_gnss, not connected" and "no alias created". He can fix that by manually creating a symlink.
When I get back to the boat I will report the error message I am getting on startup and then the Data browser info. I am seeing 10-12 satellites but my USB hub may have been shorted out by a water event (well a 53 mile double handed race with 35kt winds and 10ft waves). Not sure if this would have reset the BU-353?
That's a good idea but i still think that's a different problem, it certain needs investigation I agree. This thread is specifically about a problem where it is not possible to successfully add a serial device (GPS, multiplexer input, RS422 whatever). The only problem I have ever seen with my BU-353 is that for some reason it once switched from nmea to SIRF protocol. No idea why. Anyway, good luck. I hope you did well in the race!
