Open AT for AirLink

The Open AT Framework is a complete software package for embedded M2M application development. It offers a range of readily available building blocks which accelerate the application development process, allowing you to bring products to market faster and reduce development costs.

Key features include:

Real time: Fixed guaranteed response time
Pre-emptive: Prioritization of critical and non-critical tasks
Multi-task: Define as many tasks as you need for your programs.
VariSpeed: Enables your application to dynamically switch the CPU Clock from Standard Mode (26 MHz) to Boost Mode (104Mhz)
VariPower: Uses clock-frequency variation to choose between several modes of energy saving
Memory Access Protection: Prevents rogue memory access to unauthorized memory areas
Watchdog Protection: Can monitor the firmware and the application independently
Back Trace: Protects the wireless module against software exceptions.
Open Audio Path: Allows you do whatever is requested for your solution - from Audio sniffing, playing and recording to equalizing
DTMF generating and decoding: Allows the application to be notified by the Open AT OS when a DTMF on the microphone path or on the GSM audio channel is detected
Audio Chain Control and tailoring: Allows you to tailor the different audio filters of the embedded wireless module to ensure perfect sound rendering
Open SIM access: Allows you to connect a Sierra Wireless embedded module to your SIM server on any physical bearer (UART, SPI, Parallel...), using any data transmission protocol (PPP, IP, Proprietary...)
