    ...with the Kinomap fitness app via BLE. Hardware: ESP32: The sole hardware platform for this project. Software Requirements: FTMS Demo Program: Write a C++ program for the ESP32 to simulate a treadmill following the FTMS (Fitness Machine Service) protocol. Serial Control: The ESP32 will receive commands through the Serial Monitor to: Set speed. Adjust incline. Start/stop the treadmill simulation. BLE Functionality: The ESP32 will: Broadcast itself as a treadmill via BLE using the FTMS protocol. Send treadmill data (speed, incline, status, etc.) to the Kinomap app. Accept control commands (speed, incline, start/stop) from Kinomap and execute the appropriate changes in the simulation. Functional Requirements: Outgoing Data: The ESP32 will send data over BLE:...
