Messages send by AVL:
Message from the AVL can be sent using SMS or GPRS. In SMS only mode all data is sent using SMS.
In SMS and GPRS mode all messages are sent using GPRS. If SMS and GPRS mode is enabled and
GPRS is not available then any input activations will be sent using SMS. Whenever GPRS is available again
the unit will use GPRS again. In case real time tracking is enabled in SMS and GPRS mode and GPRS is
not available then the unit can send the data using SMS if enabled (see configuration menu).
If GSM signal is not available and input is activated then the tracking unit will send the alarm message as
soon as there is GSM signal again. The time and date in the message is from the GPS time and date at the
time the messsage is sent.
If real time tracking is enabled and there is no GSM signal then the information will be lost. The tracking unit
will still save GPS locations using the ‘GPS tracking interval setting’ if the GPS location is valid.
Any command messages can also be sent to the tracking unit in GPRS mode. Any message(s) can be sent,
but only within 2 seconds after any message is received in GPRS mode. The command messages are
identical to the messages sent using SMS.
