This application note presents the basic design rules and their applications for the HiLo modules. Some calculations and length effects can understand with Agilent Appcad tools. This document presents some basics RF principles, a method to implement HiLo modules on a PCB, and describe the main issues that electronics system designers must typically solve during the HiLo module design process.

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.

This document describes and illustrates the most common hostdevice message exchanges that occur in standard OMA-DM operations on the Sprint network.

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.

The ALEOS Application Framework provides the means to create embedded applications that run inside ALEOS devices. These embedded applications can interact with the ALEOS parameters and can access attached devices or assets. In the ALEOS AF, the AirVantage library provides access to the AV Application Services. These services provide the means to send data from the embedded application to the AV server, and from the server to the embedded application to set variable values on the device and send commands to be executed on the device.

This article provides instruction on how to use the GPS services of ALEOS AF.

This article discusses how to use the serial port in ALEOS AF applications.

This code sample demonstrates how to manage a LCD display using AirVantage Cloud Platform. It is intended to be paired with the ALEOS AF Dev Kit.

This code sample demonstrates how to exchange data with the AirVantage Cloud Platform

This ALEOS AF sample code demonstrates how to implement a Serial to TCP and UDP socket streaming solution (often known as PAD pass-through).

This article discusses the security design of ALEOS Application Framework

This ALEOS AF sample code shows how to implement SMS sending and reception in an Lua embedded application on ALEOS devices.

The Sierra Wireless ALEOS AF provides access to the radio's SMS capabilities through a set of API's. Using these API's, an application can send and receive SMS messages, choose the character encoding option, filter incoming messages by sender's phone number and/or message content

This ALEOS AF sample code demonstrates fundamental use of the RS232 port on an ALEOS AF compatible device.
