This document describes the AT command set used with the AirPrime HL7539 embedded module.

AirPrime HL7539 Declaration of European Union RoHS Compliant Product

This document provides guidelines for designing applications based on the AirPrime HL Series of embedded modules (HL6528RDx, HL85xxx and HL7xxx). It enumerates the differences between these HL Series embedded modules, and provides solutions to maximize the scalability between the products.

Android 8.1 RIL Software 8.1.3.0

Android 8.1 RIL Software 8.1.2.0

This document presents guidelines for the handling of solderable AirPrime products as they are moisture/reflow sensitive surface mount devices.

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

The Sierra Wireless AirPrime HL75xx and HL76xx modules support different power management options (sleep modes) over UART. It is imperative for the host applications to understand these power management options and exercise these options as per the platform needs.

This document is the Firmware 2.8 customer release note of the HL7539.

This document describes the network interface configuration on Linux and Windows when an AirPrime HL75xx embedded module is used.

This application note describes how to design a Dual SIM solution without using the SIM detection pin of the module.

Mobile devices using 3G and LTE are equipped with a second receive antenna for improved performance. This second antenna is required for receive diversity and MIMO. These concepts, with their associated benefits, requirements and test possibilities, are described in this Application Note in a Q&A format.

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.
