Step-by-step
1. BLE node Setup and programming
SensiBLE is – a low power, small form factor (20x30mm), ready-to-use system-on-board equipped with 3-axis accelerometer, 3-axis magnetometer, 3-axis digital gyroscope, pressure, relative humidity, ambient light and temperature sensors. Microphone, Bluetooth Low Energy (BLE) , and Low Power ARM® 32-bit Cortex®-M4 CPU with FPU are on-board as well.
SensiBLE “IoTHardware Ready” lowering the barriers for developers on the shelf Module based STMicroelectronics: BLE + Sensors + MCU.
SensiBLE enables wireless connectivity, not requiring any RF experience or expertise. Firmware, Bluetooth stack, protocols and Profiles are embedded into SensiBLE. The FP-SNS-MOTENV1 is an STM32 ODE function pack, which lets you connect your IoT node to a smartphone via BLE and uses a suitable Android™ or iOS™ application, such as the BlueMS app, to view real-time environmental and motion sensor data, and gas gauge level. Installation procedure by using the pre-compiled binary or after compiling the project can be find here BlueMS Android application : SDK makes it easy to develop applications on either system (Android™ and iOS™), by using a common programming model for both Android™ and iOS™ platforms. A BlueMS Application for Android and iOS (with a source code) is given here:

2. Create a Node-RED boilerplate app
Node-RED is a tool built on top of Node.js for IoT wiring together hardware devices, APIs and Cloud services. Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range nodes in the palette.
In this guidline, you will learn how to create an instance of Node-RED running on IBM Cloud and a Dashboard flows :
