This technical note outlines the necessary details to meet GSMA Device Connection Efficiency requirements.

This application note describes the Dual SIM Single Standby feature of the AirPrime HL Series of embedded modules.

This application note describes the antenna detection feature of the AirPrime HL Series of embedded modules.

This document provides a hardware reference design for HL6528 and HL6528-G, interfacing to a generic 3.3V host CPU or microcontroller.

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 reviews each objective with its associated requirements and then details design rules for successful Sierra Wireless mobile devices integration, with a particular focus on PCB design. It is recommended to read this application note before starting a design as its provided guidance can contribute to save time and money by reducing the number of PCB iterations before final certification and market introduction.

The Antenna Switch function enables switching between two antennas and can be implemented on customer application.This application note describes how to design a GSM antenna switch, from component selection to PCB implementation. This switching function can be used with an antenna detection system.

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 technical note describes the GNSS issue that has been observed to occur on very rare cases on HL6528-G and HL6528-G2.8V modules, and describes a workaround to overcome this issue.

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 provides a schematic diagram example of a PCM codec for the AirPrime HL6 and HL8 series of embedded modules.

This application note describes the Dual SIM Dual Standby feature of the HL6528x embedded module.

The purpose of this document is to give a general overview of the audio system in 2G M2M HL6528x and HiLoV2 modules. It describes the internal audio system blocs.

This application note explains how to use the new jamming detection algorithm in the AirPrime HL6528x embedded module via the +KJAM AT command.
