This Application Note explains the Sierra Wireless implementation for SMS Data Download. It describes: SMS data download definition in the 3GPP standard Sierra Wireless firmware behavior Advices to support SMS data download.

Devices on the management server can be viewed and managed through the web interface. This application note explains how to view details, and how to manage the units and jobs assigned to them including firmware and software upgrades. It also describes module firmware behavior and specific points around the implementation in the unit and server, plus limitations of both with good practice recommendations.

The Download over the Air (DOTA II) service is provided by Open AT Application Framework to upgrade the existing/running Open AT Application Framework embedded applications or firmware dynamically over the air.  This Application Note defines this DOTA functionality and how to use it.

Although Sierra Wireless provides Developer Studio as a library set to use over an existing Eclipse platform, some Linux developers prefer using makefiles to generate the application binary. This application note describes the toolchain used by Developer Studio and how to use it through a makefile. A sample makefile is also provided as a reference.

This Application Note describes the hands free solution available on AirPrime Q26 and WMP Series, and the SL6087 module. A brief explanation of the hands free solution is followed by a detailed presentation covering the following: Overview and block schematic Parameters explanation Tuning guidelines and default parameters

This application note describes how to use SMTP over a secured socket to send an e-mail. The application uses the GPRS interface for the SMTP transfer.

This Application Note presents the way to switch ON and switch OFF the Sierra Wireless AirPrime embedded modules, without any external microcontroller, just with the main power supply, in order to be able to wake up again when entering into alarm mode.

This application note describes the process and steps required to register and add units to the APMS server to make them available for use by a customer. This application note walks a user through the initial steps to getting up and running. If problems are encountered beyond this, support should be sought from your usual support channel.

This application note presents different antenna diagnosis solutions including their inherent limitations and different degrees of antenna default detection. Antenna diagnosis can be used to improve the reliability of a GSM link in the case of a main antenna failure by switching to a secondary one. Diagnosis can also be used as part of a production testing to check the complete connection from the GSM device to the antenna. The final part focuses on practical implementations of using an antenna with an integrated resistor.

Application Description This application is intended to show an AirLink FX programmable modem, in conjunction with the Ethernet X-card, to operate as an internet gateway allowing a PC to be plugged into it through its Ethernet port and then surf the internet. The Open AT code includes: - A DHCP server to automatically allocate IP address to the computers connected on the LAN. - A web server that prompts an HTTP page to configure the APN and related username and password.

Terranova, leading provider of software solutions for Utilities (electricity, gas, water), has developed a Smart Meter Library Suite compatible with Sierra Wireless AirPrime embedded modules (SL Series and Q Series) and AirLink Programable Gateways (GL Series and FX Series) supporting the Open AT Application Framework. This library includes a DLMS Library and a Wireless M-BUS Library.

This book will guide you through the working of Open AT with detailed step-by-step instructions. This book is also the support of the Open AT training organized regularly by Sierra Wireless, allowing developers to easily discover the world of Open AT.

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.
