When TR-102 receives this command, it will send the report back immediately
by starting the GPS function with green LED ashing. When position is xed,
green LED is on and the GPRS connection is set for the data transferring with
blue LED ash once per second. After that, it will disconnect from GRPS and go
to sleep mode with green LED goes out and blue LED comes back to standby
mode. When the specied period of time is reached, it will wake up and connect
to internet via GPRS to send the report, and go to sleep mode again. It will repeat
the same procedure when the specied period time is reached again.
Due to the GPS function is closed most of time, when it starts the GPS function, it
could take a little bit longer to get a xed position. If the GPS signal is not strong
enough, it could take more 3 minutes (also depending on the stability of GPRS
connection.)
