This Application Note describes the general structure of the Real Time Operating System implemented in Sierra Wireless modules, the RTOS features extended to developers and their restrictions, limitations and best practices to be followed when using the RTOS features.

This application note describes how to design a dual SIM solution. This function is used to switch between two SIMs. Two GPIOs are used to control the hardware switching between two SIMs.

AT Command Parser source code demonstrates and provides re-usable code showing how to subscribe and parser responses to both unsolicted and sent AT commands.

This document describes important signal considerations regarding MDL_RESET_N and W_DISABLE# signals of the MC5728V MiniCard module, and also USB enumeration and power-up timing.

This Application Note describes the power states of the Sierra Wireless MC87xx and MC77xx modules and the steps to switch between power states for power optimization.

This application note provides a schematic diagram example of a PCM codec for the AirPrime SL series.

Simple Open AT sample code giving an example of managing a TCP Client socket.

This application note describes the benefits and impacts of the various low power modes of operation available with the GPS solutions based on the AirPrime XM0110 GPS module combined with an AirPrime embedded wireless module.

This article discusses the security design of ALEOS Application Framework

This application note provides an introduction to MMS to educate the reader on the system architecture, and then explains how to use it on Sierra Wireless products.

This document gives an overview on using a private DNS server to resolve domain name on an AirPrime module.

This application note describes the three types of bus services - SPI, I2C, and parallel bus - used to communicate between two or more connected devices.

This application note gives an overview of the CMUX feature for multiplexing data over serial link, and describes the Sierra Wireless implementation of CMUX. The CMUX feature allows multiple virtual ports to be created on a physical serial link (3GPP TS 27.010).

There are currently multiple tools available to log the AirPrime Q26 Series, WMP Series and SL6087 to both debug Open AT applications and provide information to Sierra Wireless technical support for in depth analysis of problems. This document outlines the tools available, how they should be used to provide information to Sierra Wireless and developers and also suggests filters to be using in common scenario's

This application note describes the hands-free solution available on AirPrime Q268x and WMP Series. It includes a brief explanation of the solution, overview and block schematics, parameters explanation, tuning guidelines and default parameters.

This application note details how to use JTAG (an in-circuit debugging solution capable of tracking down issues which may occur in routines but cannot be reproduced with the Remote Tasks Environment), with or without various debuggers.

This application note describes the availability to send AT commands using the AirPrime Management Services portal.

This application note explains how to get basic and advanced GPS Debug information, in order to investigate GPS performance issues.

This application note provides a detailed description of the GPS Aiding solutions available wih the AirPrime XM0110 GPS module combined with an AirPrime embedded wireless module.
