NRF51822-02 NORDIC BLE4.0 low-power Bluetooth data passthrough

Module overview
nRF51822-02 module is a transparent data transmission module, the use of Bluetooth BLE, Nordic companies have integrated the SOC chip nRF51822-QAFF, internal integration of the underlying low-power Bluetooth 4.0 standard protocol, the module interface is a standard UART interface, Built-in interrupt output prompt, when pairing Bluetooth module to receive data transmission, it will output a high warning signal to the external device, and the module configuration of the hardware enable pin, no data transfer, can be set to high by the enable pin To disable serial data transfer, thereby reducing system power consumption.
