FCC Warning This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE 1: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
1 Features This module is a BLE transparent transmission module designed based on the Bluetooth Low Energy standard published by Bluetooth SIG. This module is controlled through the serial port and also supports wireless control through the host side. Users do not need to pay attention to complex Bluetooth protocol application software, and can develop standard low-power Bluetooth products in a short period of time.

Figure 4-1 5 Module Transparent Transmission Protocol 5.1 AT command configuration command refers to the command set passed by user through UART and module input command in command mode. The usage format of AT+ command will be explained in detail later. After power-on and startup, you can set the default UART of the module through UART. The port parameters are z baud rate 115200, no parity, 8 data bits, and 1 stop bit. 5.
