cambiar hora GPS uBlox NEO-6m

Adrian_E · May 11, 2016, 2:04am

alguien ha conseguido que el GPS uBlox NEO-6m devuelva la hora local, no la UTC, ya que los de ublox no dan soporte, y el soft u-center_v8.18 configura casi todo menos eso, y el restarle las horas no me ha dado buenos resultados si te muestra las 23:00 local, pero te devuelve el dia incorrecto, aca seria 10 de mayo 23:00, pero en realidad me dice 23:00 11 de mayo, asi que restar no me lo soluciona.

Este hilo tal vez sea de utilidad How do you get your time zone from GPS?

gracias surbyte, lo habia visto, ademas encontre este GPS time-date - Exhibition / Gallery - Arduino Forum, pero por el echo de ser demasiado novaton me esta llevando demasiado tiempo y los de ublox no responden mail.

Bueno este código lo probaste?

Roughly based on Adafruit example sketch: "parsing"
Utilizes the Adafruit_GPS library https://github.com/adafruit/Adafruit-GPS-Library

 Heavily mucked by M. Ray Burnette to simply use (most) any dumb serial TTL GPS for time-date

lo que mas bronca da, es que ublox no responde los mail, y el software que es el u-center, configura de todo menos eso, que menos mal que este trae un restaurar de fabrica, porque llego un momento que devolvia cualquier dato jaja, y encontre la opcion revert to default configuration sino chau gps.

Hola, estuve buscando como mejorar la idea de modificar el tiempo y realize lo siguiente:

la idea es sumar horas y restar dias...a mi me funciona tomando las horas UTC, espero sirva de idea.

saludos
