RN4871 MODULE FEATURES
The RN4871 Bluetooth Low Energy module integrate Bluetooth 4.2 baseband controller, on-board Bluetooth stack, digital and analog I/O, and RF power amplifier into one solution.
The module contains an integral ceramic chip antenna.
All products in the RN series can be dynamically configured by the host microcontroller with a few simple ASCII commands.
The RN4871 Click Board™ supports both peripheral and central Generic Access Profile (GAP) roles, actively scanning for other connectable devices instead of waiting for incoming connection requests. The peripherals are usually small, low-power devices like sensors and monitors, that broadcast information to the central device. The central device can communicate with multiple peripherals.
