3.3 Communication Settings
The CAREU WT1 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$SMSDST command to set a SMS control center phone number or short code.
For example, if the SMS control center phone number is [phone], the
AT$SMSDST command to be issued into HyperTerminal should be:
AT$SMSDST=[phone]
OK
Then you can try to use cellular phone or SMS gateway to send a SMS message to
the CAREU WT1 device. Send a SMS message --> "AT$MODID?"
Device will response:
$MODID=101000001
OK
This proves a successful mobile phone SMS connection.
