Operating procedures
1. First confirm whether the Busy pin is LOW, when the Busy pin is LOW,
You can input data through the UART Rx pin. When a string of data is transmitted, it must be
The 2byte end code 0x0D, 0x0A must be added, and the Busy pin is
HIGH (Busy pin HIGH means BLE data is being transmitted!).
2. If the BLE Module receives the data sent by the BLE Master, it will
UART Tx pin output data, the end code is the same as 0x0D, 0x0A
(The UART Tx pin does not affect the Busy pin when outputting data!)
