Bluetooth module gains audio headset firmware

Firmware for the F2M03MLA multimedia Bluetooth module simplifies connection to mobile phones incorporating the latest Bluetooth audio technology

New wireless audio headset (WAH) firmware for the F2M03MLA multimedia Bluetooth module simplifies connection to mobile phones incorporating the latest Bluetooth audio technology. The WAH firmware supports A2DP, AVRCP, HFP, HSP and SPP Bluetooth profiles. It 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 designed for embedding into high-end Bluetooth stereo headsets.

The F2M03MLA is a low-power embedded Bluetooth v2.0 multimedia module with an onboard antenna, integrated stereo amplifier and a 32bit 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 for most audio applications.

Developers can easily implement a wireless solution into their product even with limited knowledge of 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 WAH firmware, Free2move offers the F2M03M-KIT evaluation kit based on an evaluation board with extensive I/O functionality for both data and stereo audio applications.

The onboard I/O interfaces are USB, serial port, digital (SPDIF, PCM) and analogue audio.

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.
