Bluetooth® LE 5.2 Wireless Network Coprocessor
BlueNRG-2N is an ultra-low power (ULP) network coprocessor solution for Bluetooth® Low Energy applications.

It embeds ST’s most advanced RF radio IP, combining unparalleled performance with extremely long battery life.

It is fully compliant with Bluetooth Core Specification version 5.2 and supports enhanced features such as state-of-the-art security, privacy and extended packet length for faster data transfer up to 700 kbps at the application level.

The BlueNRG-2N is Bluetooth® 5.2 certified, ensuring interoperability with the latest generation smartphones and other host devices.

The Bluetooth Low Energy stack runs on the embedded ARM Cortex-M0 core. The STMicroElectronics BLE stack is stored in on-chip non-volatile flash memory and can be easily upgraded via SPI/UART and dedicated STMicroElectronics software tools.
