3.6 Communication Settings
The CAREU U1 Lite Vehicle Tracker communicates with your control center by either
SMS or GPRS (TCP/UDP). Before the device is installed into a vehicle, communication
parameters should be set.
1. SMS Configuration
Use AT$SMSDST command to set a SMS control center phone number or short code.
For example, if the SMS control center phone number is +886123456789, the
AT$SMSDST command to be issued into HyperTerminal should be:
AT$886123456789
OK
Then you can try to use cellular phone or SMS gateway to send a SMS message to
the CAREU U1 Lite device. Send a SMS message --> "AT$MODID?"
Device will response:
$MODID=101000001
OK
This proves a successful mobile phone SMS connection.
