1. boot.hex : This is the file generated by the compilation of the boot project
2. ibeacon.hex : This is the file generated by the compilation of the user project
3. s112_nrf52810_5.1.0_softdevice.hex : This is the file of the protocol stack

This is the script file file.bat. Double-clicking the file will generate the three-in-one file ibeacon_2.0.4.hex, which supports re-modifying the file name.

This function in simple_uart.c and uart_commd.c file.

The protocol Documentation path： ...BLE_APIS(nRF52)\doc\Uart Protocol

1. simple_uart.c : The initialization part of the uart driver function
2. uart_commd.c : handle Production test commands

Description of special functions:

1. void task_uart_manage(void) This is equivalent to the uart's enable and disable management functions. The specific operation is to disable the uart function after 30s, then turn on the RX io interrupt, wait data for the enable uart function of the data, and execute the corresponding cmd.

2. void task_process_uart_data(void) Uart's function to receive data. in the while function.

3. void analyze_uart_data(uint8_t cmd,uint8_t*datas,uint8_t len) Serial port data parsing function, parsing corresponding commands and function settings

4. Note: UART must be closed after the test is completed, otherwise it will cause abnormal power consumption of the device
