A friend who works in a stage production company shared that the current options for wireless microphone systems are both expensive and unsatisfactory. As a result, I took it upon myself to design a custom wireless microphone system that operates on Bluetooth technology.
To use the device, it needs to be connected to one of the microphone boxes. The system then establishes a HFP gateway, enabling it to relay incoming audio from the microphone to a wireless headset via Bluetooth, and receive audio from the headset via the connected device.
To make the device more convenient to use, I also included a wireless AP that allows for over-the-air updates of the device's firmware.
The development process involved several hardware and firmware iterations, but the final product is fully functional and ready for use.
