7: Sending Data to Your Network Application • Retrieve the Unique Mobile Device ID 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 network 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.
MP875 Modem User Guide The fast rate timer only becomes active when an alarm condition is triggered by a rise or drop in the level of one of the digital I/O channels. The default for the fast rate timer is three seconds. Note: When the fast rate timer is set to 0, a single report is sent when an I/O alarm is triggered. If the GPS timer is set to a value other than 0, it controls the frequency of reports in the absence of any alarm or event triggers.
Sending Data to Your Network Application Note: The “MP 3G Modems TAIP Reference manual” (document #2130312) provides a description of the TAIP commands you can use. This is available at www.sierrawireless.com. Information about GPS modules, including more documentation on TAIP commands, is available at www.trimble.com. If the GPS timer is set to 0, the reporting interval is determined by the configuration of the GPS module.
MP875 Modem User Guide Note: More information on NMEA message standards is available at www.nmea.org. If the module is configured for NMEA, data is sent at five‐ second intervals. (The interval cannot be changed when the module is configured for NMEA because NMEA is strictly a reporting protocol.) Monitoring and Tracking configuration You can use 3G Watcher to configure the MP modem to send MTP data to a network server: 1.
Sending Data to Your Network Application The problem created by Network Address Translation Note: A similar problem may occur if NAT is in use on your network. The host application may reside on a server that has a private IP address. You must configure the MP modem to send data to a server on your network with a public IP address, and configure the server to recognize the MTP data and route it appropriately.
MP875 Modem User Guide Note: NetMotion Wireless, Inc. develops client-server applications that attempt to overcome the issues caused by NAT addressing by assigning its own consistent private IP addresses. This software offers a potential solution to NAT issues, but it is untested by Sierra Wireless, and Sierra Wireless does not provide support for it. Solutions to the NAT problem If your service provider is using NAT, it is best to work with the provider in devising a solution.
