12 Location Report Command
12.1 Standard Report – AT$SR
This command will send one or more standard reports via the selected channels.
Note:
1. If the device is unable to acquire position, the last valid position will be sent with
status indicator marked as invalid. The device will start afresh and will not keep the
last valid position if power is cycled. In the case of no valid position at all, all the
GPS data fields (date, time, latitude, longtitude, speed, heading) will be set to 0.
2. If the user is trying to send standard report while the GPS is in sleep mode, the
device will send out an unsolicited response to indicate GPS sleep.
3. If the user is trying to send standard report while the GPS is not operational, the
device will send out an unsolicited response to indicate GPS not operational.
4. If the user is trying to send standard report via inactive network channel, the device
will send out an unsolicited response to indicate inactive network channel.
5. If the user is trying to send standard report to a SMS number which is not defined,
the device will send out an unsolicited response to indicate undefined SMS number.
6. Once maximum reports (set in $DB command) are logged, the device will overwrite
the report data in the memory in FIFO order, at the same time, it will send out an
unsolicited response to indicate memory full.
7. Note that excessive data log (e.g. data log and dump every min) may result in
overwritten data flash beyond the life cycle.
8. Note that it is not recommended to send $SR via SMS at less than 10sec interval.
