ATTENTION!
Total length of an SMS command string
should not exceed 160 Latin characters. Number of
commands per one SMS is only limited by the maximum
length of an SMS.
It is also essential to observe the order of the commands, when
they are sent in one SMS message. The device reads and performs the
commands in sequential order. E.g.,: once the
cpureset;
command is
received the device processor will reset and the commands will not be
further performed.
Correct:
setparam 0242 <APN>;
setparam 0245 <HOST>;
Incorrect:
setparam 0246 <PORT>;
cpureset;
setparam 0242 <APN>;
cpureset;
setparam 0245 <HOST>;
setparam 0246 <PORT>;
When login and passwords pairs are configured for access using
SMS, they must be included to each SMS with the commands. If a
login/password pair is enabled, but not included to an SMS with the
commands, such SMS will be ignored. If a login/password pair option is
not enabled, it will not be checked.
In the event that one of the authorized phone numbers is enabled,
SMS commands will only be performed provided that they have been
sent from one of the authorized phone numbers (login/password is also
required, if enabled). If there is no authorized phone number enabled,
SMS with commands will be received from any phone number.
Configuring the Device
The BI-820OBD TREK Tracking Device can be configured by one of
the methods below:
1. Using a direct connection between the device and a computer.
2. Remotely, using SMS commands.
Configuration of the device by any of the methods available only
requires configuring necessary device parameters. Each parameter has
its own unique ID. Special commands are used to read/record the values
of a selected parameter.
In case of remote configuration of the device using SMS, one
should bear in mind that the total length of an SMS should not exceed
160 Latin characters. Number of commands per one SMS is only limited
by the maximum length of an SMS.
All commands for device manipulation can be divided into the
controlling and information ones.
