BlueNRG-Tile has enough processing power to control several sensors while using Bluetooth to communicate with a free iOS or Android app. The device supports mesh networking, with up to 32 nodes to allow it to be deployed in multi-node applications. BlueNRG-2 SoC is powered by an Arm Cortex-M0-core with up to 256KB of embedded flash memory.

The SoC is supported by an ultra-low-power sensor portfolio. Sensors on the tile include an accelerometer and gyroscope, a magnetometer, pressure, and humidity and temperature sensors, a microphone, and a FlightSense Time-of-Flight sensor. The solution has 900 nA sleep current (with full data retention) and full-system stand-by power down to 25uA. It has fast wake-up capability and can efficiently execute a 9-axis inertial sensor fusion (on the ST MotionFX sensor-fusion code optimised for the Arm Cortex-M0) and stream real-time, low-latency data while using 1.4mA at 25 Hz.

With a board size of 2.5cm diameter, the BlueNRG-Tile development kit offers an on-board debugging and programming interface, multi-color LED, and a configurable wake-up push-button.

The sensor node is part of a comprehensive SDK that includes BlueNRG-Mesh networking library, MEMS sensor algorithms including 9-axis sensor fusion and event detection, voice-over-BLE code and examples in source code. In addition, ST BLE Sensors and ST BLE Mesh apps, for iOS and Android smartphones and for both mesh and point-to-point networking, are available for download from the app stores.
