Halmstad, sweeden - Wireless Audio Headset (WAH) is a new firmware from Free2move developed for the Multimedia Bluetooth module F2M03MLA. The firmware is designed for easy connectivity to mobile phones incorporating the latest audio features in the Bluetooth technology. Following Bluetooth profiles are supported in WAH: A2DP, AVRCP, HFP, HSP and SPP where all profiles are acting as the headset side for communication with e.g. mobile phones. The firmware can either be controlled individually with a button interface or from an external microcontroller using the UART interface with easy to use AT-commands. The F2M03MLA module with the WAH firmware is typically embedded into high-end Bluetooth stereo headsets.
F2M03MLA is a low power embedded Bluetooth v2.0 multimedia module with an on board antenna, integrated stereo amplifier and a 32 bit Digital Signal Processor (DSP) for audio coding and advanced noise and echo cancellation. With a transmit power of up to +8dBm and receiver sensibility of down to -81dBm combined with stereo sound and low power consumption the F2M03MLA is suitable in most audio applications. Developers can easily implement a wireless solution into their product even with limited knowledge in Bluetooth and radio design. The module is fully Bluetooth v2.0 qualified and it is certified according to CE and FCC.
To evaluate the F2M03MLA together with the Wireless Audio Headset firmware, Free2move offer the evaluation kit F2M03M-KIT which is an evaluation board with extensive I/O functionality for both data and stereo audio applications. The on-board I/O interfaces are USB, serial port, digital (SPDIF, PCM) and analogue audio. The evaluation board is primarily made to evaluate the Wireless Audio firmware but it is also possible to use for other firmwares and customer specific applications. The evaluation board gives the possibility to upgrade the Bluetooth module with new firmware or updates using Free2move's Flash Utility software which is included in the kit.
Flash Utility is Free2move's generic application software which allows the user to easily change and upgrade the firmware as well as changing advanced settings on the Bluetooth module. Flash Utility automatically search for, and download, the available firmware updates from the Free2move server, which makes it very easy for customers to enable new firmware releases in a fast and simple manner.
