Lantrix T-1700 3G

Hi anton, my problem is the following:

I have a Lantrix T-1700 3G connected to my own traccar server, but the reports are ten minutes late, as if it were ack problem.

it should be noted that it would not be a protocol problem since, although they are late, the reports appear.

Try to connect it to other GPS software and the reports arrive without delay.

excuse my english, greetings and thanks.

Your problem is that you have the wrong ack, the team is sending the same package N times, until you let it pass and send the next one.

excuse my english, greetings and thanks. XD

Me parece que los dos hablamos español, estoy en lo correcto?

Entiendo lo que dices, pero como lo podria solucionar? Gracias por la respuesta

Asi es, el problema esta en que en que los lantrix que se venden en argentina implementan un ACK diferente, en su momento trabaje con Marcelo de la fabrica para resolver varios problemas sobre este protocolo.
la solución es re escribir las partes que detectes que fallen, con gusto podria ayudarte.

Saludos Santiago Ligenza

Gracias santiago, voy a leer lo que recibo en el log del traccar y por lo que me das a entender, voy a tener que modificar el codigo fuente de traccar, acorde a la documentacion de ese dispositivo para que funcione correctamente. Ni bien tenga mas informacion te escribire

Esto es lo que recibo en el traccar:

Y esta es la documentacion del gps:

Si efectivamente el ack del protocolo que usa tu equipo no corresponde con el de traccar debes re compilar la clase con las modificaciones, tambien veo que informa la velocidad en km/h y no en nudos, ni hablar de las notificaciones que ninguna corresponde al evento. en fin todo menos la toma de posición debe ser modificado

=Saludos Santiago

Pude modificar todo, muchas gracias santiago!
