This document provides steps to configure RF bands and customize the HL78xx for specific operators, and explains the impact of these settings.

HL7800/HL7800-M/HL7802 firmware release 4.7.1.1

This document describes methods (excluding FOTA) for upgrading HL78 Series firmware images.

This video shows how to use AT commands to create a raw TCP session from an HL78 module UART/USB interface through to a server with an open port/public IP address. The same commands are employed across the HL and RC families of products.

When using the HL78 module, for network or application problems it may be necessary to be view the internal operation of the unit. To do this logging from its debug port is required. This video shows how to carry out this logging, resulting in a file that can be sent back to Sierra Wireless for analysis.

In embedded designs CMUX is a popular mechanism to use where an external PPP dial-up connection is used rather than the onboard IP stack. This allows the application firmware to have the connection up while still performing other operations on the unit such as querying network status, etc. This video walks through the tools that can be used on a Linux system to start CMUX, and its operation.

From a UE (user equipment, so a handset/module) perspective there are a number of parameters that are critical to its operation. This video explains what these numbers are, where they come from and how they are used. It is applicable to all UE's on the market.

Within mobile networks there are different ways of being attached to a 3GPP PLMN (public land mobile network). This video explains the different types of attach statuses and how they can affect and influence data connections you are using.

In some applications, the ability to know the location of the unit without powering up a GPS is useful. Using the method shown in this video, an application can perform a geolocation operation through the use of a pure cell ID. This is demonstrated using the WP7607, which is a 2G/3G/4G module. However, any module can be used.
