A newer firmware version iWRAP 4.0 is announced for this module. Please see WT12-A-AI4 instead.
WT12 is a next-generation, class 2, Bluetooth 2.1 + EDR module. It introduces three times faster data rates compared to the existing Bluetooth 1.2 modules even with a lower power consumption. WT12 is a highly integrated and sophisticated OEM Bluetooth module, containing all the necessary elements from Bluetooth radio antenna to a fully implemented protocol stack. Therefore WT12 provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their designs with limited knowledge of embedded Bluetooth and RF technologies.
WT12 module combined with Bluegiga’s complete development, testing and verification services and excellent developer support, OEMs and designers ensure that their products reach the market rapidly and cost-efficiently in relation to time and resources. Bluegiga has extensive in-house knowledge of both software and hardware offering customers a single point of contact to all internal Bluetooth related issues.
By default WT12 module is equipped with powerful and easy-to-use iWRAP firmware. iWRAP enables users to access Bluetooth functionality with simple ASCII commands delivered to the module over serial interface. Entering the world of Bluetooth wireless technology could not be easier!
With iWRAP software you have several implementation options:
- iWRAP can be configured to operate autonomously, - as a Bluetooth cable replacer
- To create sophisticated applications - a host system can be used to control iWRAP with ASCII commands
- With The GPIO interface in WT12 module can be used to connect host and iWRAP
Besides the iWRAP firmware Bluegiga also offers several other firmware options for WT12 module. Standard Host Command Interface (HCI) firmware is supported and an ideal solution for systems where the host system is capable of running the entire Bluetooth stack and profiles and WT12 is utilized as the physical radio over UART or USB interface.
