Description
AI
The BlueNRG-2N is an ultra low power (ULP) network coprocessor solution for Bluetooth®low energy applications.
It embeds the STMicroelectronics’s state-of-the-art RF radio IPs combining unparalleled performance with extremely long battery lifetime.
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 application level.
The BlueNRG-2N is Bluetooth®5.2 certified ensuring interoperability with the latest generation of smartphones and other host devices.
The Bluetooth low energy stack runs on the embedded ARM Cortex-M0 core. The STMicroelectronics BLE stack is stored into the on-chip non-volatile Flash memory and it can be easily upgraded via SPI/UART as well through the dedicated STMicroelectronics software tools.
