Hey,
Having some trouble getting the callbacks to invoke with the generic library on zephyr 1.7.1
to my understanding once it gets the data it should call it. have i misunderstood the setup ?
an example
/*
// example data set TODO parse this properly + modify the struct + learn what the other parameters are doing
// <UTC> 091635.000, UTC time (hhmmss.sss)
// <latitude> 3913.6952N, Format: ddmm.mmmm N/S dd: 00..90, degrees || mm.mmmm: 00.0000..59.9999 min || N/S: North/South
// <longitude> 00904.1505E, Format: dddmm.mmmm E/W ddd: 000..180, degrees || mm.mmmm: 00.0000..59.9999 min || E/W: East/West
// <hdop> 0.7, Horizontal Dilution of Precision TODO look this up lol
// <altitude> 17.9, altitude - mean-sea-level (geoid) in meters
// <fix> 3, fix type status ? whats the difference between 2D and 3D fix ?
// <cog> 0.0, Course over Ground (degrees, True)
// <spkm> 0.0, speed over ground (Km/hr)
// <spkn> 0.0, speed over ground (knots)
// <date> 290920, date of fix dd: 01..31, day mm: 01..12, month yy: 00..99, year 2000 to 2099
// <nsat> 10 total number of satellites in use 0-12
