Re: Getting NMEA data out from gpsd for use in u-center

[Frank Nicholas]

Hello David,

I think you missed the point about why, for you, “u-center doesn't connect or 
doesn't recognise udp/tcp on 2947”.

Did you ever try u-center & GPSd with the “-G” option to tell GPSd to allow 
external network connections?  Without it, an external network connection to 
GPSd would have never worked, and this is most likely why you determined 
“u-center doesn't connect or doesn't recognise udp/tcp on 2947”.

Thanks,
Frank
