Wavecom has announced the commercial availability of its Open AT Software Suite version 2.0.
The next generation software architecture represents continuing improvement and innovation that allows developers to write application code in two popular programming languages: C and Lua - C for efficiency and code compactness and Lua for ease of development and code security. The developed code can be re-used, without modification, on multiple Wavecom Wireless CPU devices from Plug & Play to Quik to Wireless Microprocessor families. This portability feature allows the growing number of Open AT developers to benefit from re-using previously developed code.
In addition to application portability, the newest version of Open AT comes with a wide variety of value added features that specifically target remotely installed machines where cost optimisation is critical to a product's success. One such significant advance is the ability of the pre-emptive RTOS (realtime operating system) to support multitasking, a much anticipated feature of the Open AT customer base.
This unique RTOS allows direct access to hardware resources within a guaranteed response time upon interruption, whatever the GSM, GPRS or EDGE state of the wireless CPU (active or not) and full access to the audio path for complex audio processing via simple APIs. The monitoring of the application's multitask structure is made through a programmable application-dedicated 'watchdog' which is tuneable depending on the processing to be performed and debugging is made easier using JTAG probes.
Finally, the firmware has been upgraded to support Wavecom's secure Intelligent Device Service (IDS) offer, providing customers with access to a powerful Web-based service platform for upgrading and monitoring networked machines.
