Description: The project's objective is to create an innovative integrated circuit that combines wireless technology for audio transmission (Bluetooth Classic and Low Energy) with DSP and True Wireless Stereo in one chip. In Comarch, our responsibility is the creation of the FW part of the chip. Our main goals are implementation of audio handler, audio multiplexer, synchronization protocol and TWS integration

Technologies: C, TWS, DSP, Bluetooth Low Energy and Classic, ARM

Others: Electronic measurements, analyzing Bluetooth traces and logs, complex debugging

Team: 1 Product Owner, 1 Scrum Master, 10 Developers

Description: The primary goal of the project is to implement the platform dedicated for supporting hearing aid devices with Bluetooth connectivity. Comarch’s task is to support the client in creating high quality firmware with use of C++ and Python, and to provide a test framework for Bluetooth modules. The entire project is managed in SAFe (Scaled Agile Framework) methodology, with every team working in Scrum. When the platform creation is done, final products will be developed and put on the market to help treat hearing disorders
