This application note explains the details of BootROM with BROM.DLL handshaking and flash download / format process and helps users upgrade firmware images that can be sent to a target (GNSS module) via the RS232 (UART) interface via their hosts.

The HL7588 embedded module supports dedicated data bearer in the firmware. This technical note describes how to enable dedicated bearer via the appropriate use of supporting AT commands.

This application note provides all necessary information to perform Firmware Over-The-Air (FOTA) and Software Over-The-Air (SOTA) on Sierra Wireless AirPrime WP Series modules. This application note applies to all products in the AirPrime WP8 and WP7 Series.

The Sierra Wireless MDM9X15 and MDM9X30 family of modems support carrier switching. This is a feature where the same modem can be used with different carriers from different geographies by downloading and activating the correct FW package for the carrier and modem. This document explains how customers can match a FW package with the correct supported modem.

Contains an application note describing how to use the BC188 User Flasher to copy Firmware Images to and from the integrated BC188 Flash Memory.

Contains an application note describing how to use the Melody Device Firmware Upgrade Tool.

Contains an application note describing the update procedure for upgrading the BC119 from MelodySmart v3.4.x to V3.7.0+.

This Application Note details how to handle the main audio features supported by an audio enabled MC7304 module. Two main capabilities are discussed.

AirPrime WP modules flash firmware guidelines.

This application note provides all necessary information to perform Firmware Over-The-Air (FOTA) on Sierra Wireless AirPrime HL Series modules. This application note applies to all products in the AirPrime HL6, HL7, and HL8 Series.

This application note describes the successive firmware versions needed to upgrade an HL6528-G or HL6528-G2.8V module from one version to another.

This application note describes Firmware modifications implemented to make the HL6528x embedded module resistant to power outages during a FOTA upgrade, and explains how users can make their devices more robust against power outages.

This application note describes the steps needed to get debug logs (using Mobile Analyser and 3G Firmware Trace Tool) for the HL854xx on Windows and on other OS, either through USB or UART.

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.

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.

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.

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.

Data communication from Sierra Wireless modules is done through the Data layer, which is a part of the firmware. AirPrime module support both Fax class 1 and class 2. They are implemented as a library in the Data layer. The Fax library manages all Fax related operations for the module.
