Note: after each reading operation, this callback function will be performed. The application layer saves the
data that is read in this function.
About the details of scanning, connecting, and other communication operations, please refer to the test APP source
code (BLE Transmit Module v1.29) for transparent transmission in iOS, in which it realizes, for FFE9 and FFE4, the
operations of data transmit from BLE to serial port and from serial port to BLE characteristics (notify and write). Other
