This Application Note presents the steps to set up a PPP connection in Linux Operating System using the Sierra Wireless embedded module. As Windows® and Linux® have different procedures for creating a PPP connection, this application note provides details about the process for Linux environment. The steps to create the connection are well supported with images to graphically depict those steps.

This application note describes how to perform voice over IP using PCM (for 3G modules) and AMR (for 2G modules).

This Application Note describes a method to wake up an embedded module by motion detection through the use of a 3 axis accelerometer. Generally, when an AirPrime embedded module is not needed in working mode, the best way to save energy is to enter into ALARM mode. It can then be woken up by programming an RTC interrupt. However, in specific applications, it can be useful to wake up the AirPrime module when a movement is detected. This application note shows a method to implement this mechanism.

The purpose of this application note is to provide a first level of suitable information to select and implement a power supply solution for a GSM application.

This Application Note describes methods and services through which an application will be able to perform a Geolocation operation through the use of purely CellID’s without the need for GPS.

This document gives examples on how to perform extended FTP functions (such as file delete, get file size, file listing and resume download) on the Internet Application with TCP sockets.

Data communication from Sierra Wireless modules is done through the Data layer, which is a part of the firmware. Sierra Wireless modems support both Fax classes. They are implemented as a library in the Data layer. The Fax library manages all Fax related operations for the module. This Application Note explains how to send and receive faxes.

This Application Note describes the RS-232 PC cards models that are recommended (or not) for High Speed Transfer by Sierra Wireless.

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.

This application note gives an overview of the CMUX feature for multiplexing data over serial link, and describes the Sierra Wireless implementation of CMUX for Q26 Elite. The CMUX feature allows multiple virtual ports to be created on a physical serial link (3GPP TS 27.010).

This application note describes all the steps required to activate an AirPrime Q26 Elite CDMA 1xRTT module on the Verizon network.

This application note describes all the steps required to activate an AirPrime Q26 Elite CDMA 1xRTT module on the Sprint network.
