ESP32 TWS Earbuds Firmware Development

@tshibsamuel477

Hi there, I’ve carefully read your brief and can deliver this faster than expected. I’ve worked with all the components you mentioned—ESP32, the SIMCom A7672S, TWS earbuds—and have implemented Bluetooth HFP call handling, including SCO audio routing, I2S/PCM bridges, and AT-command control over UART. I can build firmware that pairs the A7672S voice path to TWS (downlink) and routes TWS mic audio back to the A7672S (uplink), with auto-answer, call state management, and robust audio processing (AGC/echo/noise controls) for seamless performance. My background spans embedded C/C++, real-time audio on ESP32 (Classic BT + BLE), and production-grade integration of telecom modules. If you message me, I’ll share a concise development plan, timeline, and milestone breakdown aligned with your requirements. Best regards, Samuel Tshibangu
