This bluetooth module is based on NORDIC nRF51822-QAFF, is with low power consumption. Its transmission range is 0 to 20 meters.
The bluetooth module is based on NORDIC SOC chip nRF51822-QAFF. Its interface is standard UART, built-in interrupt
output prompts. When this module received data from paired bluetooth module, it will output high level cue signal
to notify the external device. The module configurate hardware enable pin. If there is not data transmission, it
could set high the enable pin to disable serial data transmission, thereby reducing the power consumption of the system.
