This Application Note describes the audio design guidelines to optimize the implementation of hardware, gains and algorithms tuning of the AirPrime SL808xT, SL808xBT, and SL808xBTA embedded module.

This application note presents the recovery mechanism of the Open AT Application Framework. The goal of the mechanism is to avoid infinite and uncontrolled reset loops in the firmware.

The Open AT Source code example allows to use the file system to store application data using AT commands.

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.

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.

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.

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

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

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 steps to open an FCM flow (V24 serial flow, GSM flow or GPRS flow) in an application. It includes a sample using a custom AT command to read data from the flash and send them to the external application using the FCM V24 serial flow.

This application note explains how to use the Watchdog Timer Reset function. Designed for remote devices requiring automatic operation, it generates a hardware reset to the module if the Open AT embedded software hangs, allowing the software to restart.
