This application note explains the Sierra Wireless implementation for PLMN selection and reselection. It also includes a PLMN reselection FAQ.

The Sierra Wireless C-GPS Plug-In (now replaced by the Location Library) facilitates the integration of GPS functionalities. The library drives a companion GPS chipset; here, the Opus III from eRide, Inc.

This library for Open AT handles: Jamming Detection, Secured Sockets Layer SSL 3.0 / SSL 2.0, Secured Internet Protocols HTTPS, Message Digest algorithms (MD2, MD4, MD5), Secure Hash Standard algorithms (SHA, SHA-1, SHA-2, RIPEMD160), Encryption algorithms (DES, 3DES, AES, RC2, BLOWFISH, ARCFOUR, CAST-128), Public key cryptography and key agreement (Random, Bignum, Diffie-Hellman, RSA and DSA), Secure data storage.

This library offers TCP/IP features including UDP and TCP sockets, file transfer protocol (FTP client), email (POP3/SMTP), HTTP, SNMP, PING and MMS. It also enables gateway functionality and IP routing management by providing DHCP server, Port Forwarding, DNS proxy, and NAT feature.

This 500-page programming guide will guide you through the workings of Open AT with detailed step-by-step instructions. We recommend using the fullscreen mode and zoom function for better reading comfort.

The Open AT Application Framework embeds 2 tutorials to let you discover Open AT concepts and APIs.

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.

This application note describes some concepts in using Developer Studio and shows various snapshots in using it. These snapshots shows the sequence of using Developer Studio, and also functions as a quick start-up guide.
