2G 4G Problem
I don't think it's related to cell network.
Thanx for the very quick response. So I have to search on.
My gps trackers response to status sms:
BAT:6, GPRS:1, GSM:3,GPS:0,ACC:0,oil:0,Power:1,S:0
I am not sure, if GPS:0 has to be GPS:1, but if I ask for Google Coordinates, the tracker sends the correct values.
The interesting fact is, that all 3 trackers behave the same.
I have 3 china trackers since many years. In August my SIM fron blau.de was switched off and I had to renew the contract. Since then the tracker still connects to the traccar server, but gps data is only transmitted, when the trip starts.
Is this behaviour due to a switch off of the 2g protocol?
