BlueVoice_LinuxClient

A Python Linux Client for the BlueVoice functionality of ST sensor boards. Tested on ST BlueTile.

What's BlueVoice

BlueVoice is an application developed by ST for some of their sensor boards that are equipped with a microphone. With BlueVoice, it is possible to stream audio data from their microphones to a client using only Bluetooth Low Energy technology.

What's working

The client will connect to the device and start getting audio data from the device. As soon as the user hits Ctrl+C, the client will disconnect from the board and save a file with the audio sample in int16 format. If you set the 'reproduce' variable accordingly, the recorded audio can be played.

Working on

Some problems may arise when reproducing the audio, due to the sounddevice library. Future work is to solve (or workaround) these errors.

How to

• Make sure Python 3 is installed on your Linux system.
• Install the required libraries using pip: pip install gatt sounddevice
• Modify the mac address in the .py file with the one you intend to connect to.
• Set the variable 'reproduce' to True if you want to hear the result, False if you only want the file to be saved.
• Open a Terminal and issue the command python3 client_bluevoice.py
