You could define the content of report and the report interval of motion
mode.
If you want to save the battery power, you could turn off GSM module in
static state by making parameter RA=1.
In motion mode, TR-203 will make GPRS connection while sending static or
moving report. After sending report, it will cut the GPRS connection. If you
want to keep GPRS on-line, you could set RB=1 to keep GPRS on-line in
static interval and set RC=1 to keep GPRS on-line in moving interval. Some
telecom operator will kick off the continual GPRS connection. So you could
make GPRS connection cut and then make the GPRS connection again
according to a regular interval by parameter E4. You could also make
TR-203 to check if GPRS connection is on-line according to a regular
interval by parameter E5. If GPRS connection is cut, TR-203 will try to
connect to server for one time.
In order to avoid TR-203 jump to static state as soon as it does not detect
motion, you could set TR-203 keep in moving state by setting a traveled
distance (RE) within a defined interval (RF).
