NRF51822-02 NORDIC BLE4.0 low-power Bluetooth data passthrough
nRF51822-02 module is a data transparent transmission class module, using a Bluetooth MCU BLE Nordic companies are integrated SOC chip nRF51822-QAFF, the internal integration of the underlying low-power Bluetooth 4.0 standard protocol, the module interface is a standard UART interface, built the interrupt output prompts, when pairing Bluetooth module receives data transmission, will output a high level warning signal to inform the external device, while the module configuration of the hardware enable pin, without the need for data transmission, can through the enable pin is set high to disable serial data transmission capabilities, thereby reducing power consumption of the system.
