Illustration of Working Mode
The Bluetooth Low Energy modules can work in bridge mode (transparent transmission mode).
After being started, the module can broadcast automatically,then the Smart phone scan and pair with it. When the connecton is successful, the smart phone can monitor and control the module through Bluetooth protocol.
In bridge mode, user’s MCU can communicate with the mobile device bi-directionally through module's UART. Users can also manage and control certain communication parameters through specific serial port AT commands. The detailed meaning of the user’s data is defined by the up-application. Mobile devices can write the module through the APP. And the data written will be sent to the user MCU through serial ports. Then the module will transmit the data package from user MCU to the mobile devices automatically. Under the development in this mode, the user needs to undertake the work of code design for master CPU, and the code design of APP for smart mobile terminals.

Pin No. Module Chip I/O Description
Pin Pin
Name Name
Pin1 GND Ground
Pin2 VCC Power supply 1.8V~3.8V
Pin3 TMS I/O Connect the TMS of XDS simulator
Pin4 TCK I/O Connect the TCK of XDS simulator
Pin5 RST Reset and effective at low level,no internal pull-up.
Pin6 EN P06 I Module-enabled control line (level trigger mode as default,no internal pull-up)
- Level trigger mode - Active when low level, without internal pull-up.
0: Module starting to broadcast, until connected to the mobile device
1: Entering sleep mode immediately, regardless of the current status (0.1µA)
Pin7 P09 I/O  
Pin8 GND Ground
Pin9 GND Ground
Pin10 P08 I/O  
Pin11 P07 I/O  
Pin12 Link instruction P05 O Link instruction
0:BLE connected
1:BLE unconnected
Pin13 Broadcast instruction P04 O Broadcast instruction
0:Open broadcasting
1:Close broadcasting
Pin14 BRTS P03   As the data sending requests (for module wake-up)
- 0: Host has data to send, and module will wait for data transmission from the host so will not sleep
1. Host has no data to send, or data has been sent. So the value of the signal should be set at “1”.
Pin15 BCTS P02 O Data input signal (for host wake-up, optional)
- 0: Module has data to send, and the host will receive the data.
1: Module has no data to send, or data has been sent, and thevalue of the signal will be set at “1”.
Pin16 TX P01 O Serial port TX
Pin17 RX P00 I Serial port RX
Pin18 NC
