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.

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.

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 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.

The CF3 concept introduced by Sierra Wireless, and its companion product the snap-in socket, are a significant step forward in enabling the user to test multiple types of units on a single board. The snap-in socket, when handled correctly, is a robust and flexible tool to enable this but it does need to be handled properly with units being inserted and removed correctly. Otherwise it can result in fatal damage to the lid, socket, and potentially the unit. This video walks through this process to make sure the correct procedure is applied.

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.
