* @brief VesiScan BASIC main header file
|
|
*
|
|
* [System Overview]
|
|
* VesiScan BASIC is an nRF52840-based BLE bladder monitoring patch device.
|
|
* This header defines enums, function declarations, and global variables used system-wide.
|
|
*
|
|
* [Communication]
|
|
* - BLE NUS (Nordic UART Service): binary protocol with smartphone app
|
|
* - Physical UART (1Mbps): debug and factory testing
|
|
*
|
|
* [Data Transmission Flow]
|
|
* 1. Receive command from app/UART -> received_command_process()
|
|
* 2. Collect sensor data (battery, temperature, IMU, pressure)
|
|
* 3. Build binary packets via format_data() family
|
|
* 4. Transmit over BLE with CRC16 appended via dr_binary_tx_safe()
|
