Accelerate BLE wireless-sensing projects for Android or iOS

The framework is a great springboard for developing IoT devices, wearable electronics and other wireless-sensor applications that require high performance and very low power consumption.

BlueMicrosystem1 comes with libraries including a real-time motion-sensor and a sample barometer application that speeds adoption by showing how to build fully functional wireless sensor nodes. The ready-to-run barometer application is built by easily connecting three boards: an STM32 Nucleo F4 MCU board (NUCLEO-F401RE), a MEMS and environmental sensor X-NUCLEO expansion board (X-NUCLEO-IKS01A1) and a BLE expansion board (X-NUCLEO-IDB04A1).

The sensor expansion board contains a humidity/temperature sensor, a MEMS barometric pressure sensor, an inertial module featuring a 3D digital accelerometer and 3D digital gyroscope and a 3-axis MEMS magnetometer, which all together provide 10 degrees of freedom position sensing. The Bluetooth expansion board contains ST’s BlueNRG low-power network coprocessor with built-in 2.4GHz radio. BlueMicrosystem1 includes drivers that recognise the transceiver and sensors. The STM32 Nucleo MCU boards cover all STM32 product series, allowing developers to choose the type of MCU that best suits their application needs.

ST’s Open Software Expansion development suite, which includes Open.Framework, Open.MEMS and Open.RF, offers drivers, middleware and application software to jump-start IoT and embedded designs with a broad range of compatible and complementary products, including sensors and radios. The suite enables fast prototyping using leading-edge components to accelerate time-to-market.
