NMEA and PPS different with build a pi

[mikey1963]

Without this build my pps time signal works fine but when build a pi is installed my pps signal just times out and is therefore unusable. Also my NMEA output seems to be significantly slower than internet connected devices. Without build a pi my gps whoops internet connected devices. Having scanned thru the code I can't see anything affecting it, anyone else throw any light on this?

There is only one section in the code where BAP modifies things pertaining to the GPS.

https://github.com/km4ack/pi-build/blob/master/functions/base.function#L74-L85

You might compare /etc/default/gpsd.org to the current gpsd file to see if any of the BAP changes are causing this.

Thanks I had already found this and like you , I can’t see anything in there to effect it. I think the only other thing to try is to not use shared memory segments. Perhaps use some other directly device addressing line in the chrome conf file I guess. I will keep investigating. Thanks for a great script. Mike de M0JUJ
