The RN4080 module from Microchip provides a complete solution to implement Bluetooth 4.2 Low Energy connectivity.
All products in the RN series can be dynamically configured by the host microcontroller with a few simple ASCII commands.
The RN4870 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.
It also supports Remote Command mode which allows a remote device to access Command mode remotely via Bluetooth link.
The module contains an integral ceramic chip antenna.
