or an AT command.
This chapter discusses how to configure the MP modem to
send GPS and I/O data to a network server. This is a simple
process, but if there are any firewalls on your or your service
provider’s network, the data must be routed through or
around the firewall. A general discussion of some methods of
dealing with firewalls is provided.
This chapter also explains how to retrieve the Unique Mobile
Device ID from the MP modem. This is the number that
uniquely identifies each MP modem. Any application that uses
the GPS and I/O data from the MP modem requires this
number.
Configuring the MP modem to
route data to a server
The protocol that defines how MP modem data is packaged is
called MTP (Monitoring and Tracking Protocol). You can
configure MTP in 3G Watcher by selecting
Tools > Options >
MP > Monitor and Tracking
, or by using the AT command
AT!MPMTCONF and the appropriate parameters.
The MP modem provides four independent reporting engines,
allowing data to be sent to four different destinations. You can
specify the destination IP address and port number for each
engine. This allows, for example, GPS data to be sent to one
host application, and I/O data to be sent to another.
You can also specify the values for the timers that determine
the frequency with which the data is to be sent.
Report frequency timers
The low rate timer, alert rate timer, and GPS timer control the
interval between reports from the MP modem.
