The Microchip RN4871 BLE module is based on the IS187x Bluetooth RF SoC and is ideal for easily adding wireless connectivity to your IoT and wearable designs. The RN4871 provides a control interface to the IS187x IC, based on ASCII commands over UART.

BLE stands for Bluetooth Low Energy (sometimes referred to as Bluetooth Smart) which is a version of Bluetooth with very low power consumption, perfect for compact portable devices. With the addition of a Bluetooth device, such as a BLE-enabled smartphone, the RN4871 also enables you to control and monitor your application remotely.

The RN4871 Bluetooth module provides a complete solution to implement Bluetooth 4.2 Low Energy connectivity, in a compact form factor. The module is interfaced to a host MCU via a UART serial port using Microchip’s ASCII command set for easy integration into most applications. The module can be dynamically configured by the host MCU with a few simple ASCII commands. The RN4871 also supports onboard scripting to automate basic operations enabling it to stand alone without a host microcontroller.
