Avnet Silica / Mbed OS sensor-node-ble

Silica Sensor Node board sends custom ble advertising for the Gateway board

Dependencies:   X_NUCLEO_IKS01A2_SPI3W

Fork of sensor-node-ble by Roberto Spelta

Getting started with mbed SensorNode BLE

Information

History project:

  • 26/01/2017 - First Release

This project uses the Bluetooth Low Energy in order to send advertaisments every second. These payloads are read by the Visible Things Gateway board, more about it here . Every advertaisments contains sensors data read form the SensorTile and the Silica Sensor Board. For details please read the document in the MAN folder,

The application:

  • reads sensors data (accelerometer, gyroscope, lux, pressure, temperature, proximity, magnetometer)
  • send these data by BLE

You can compile this project in three ways:

1. Using the Online compiler.

Information

Learn how to use the Online compiler reading https://docs.mbed.com/docs/mbed-os-handbook/en/latest/dev_tools/online_comp/ page.

2. Using the compiler on your PC

Information

Learn how to use the mbed-cli reading https://docs.mbed.com/docs/mbed-os-handbook/en/latest/dev_tools/cli/ page.
The name of the machine is SILICA_SENSOR_NODE.

3. Exporting to 3rd party tools (IDE)

Information

Learn how to use the mbed-cli reading https://docs.mbed.com/docs/mbed-os-handbook/en/latest/dev_tools/third_party/ page. We have exported the project for you, please read here

Warning

This example requires a Visible Things Gateway board. If you don't have this board you can use RF Connect app from an Android phone just to see the raw data sent from the SensorNode.

rspelta 3:94aee6f716b7 8 * The VL6180x by ST micro is a time of flight range finder that
rspelta 3:94aee6f716b7 9 * uses pulsed IR light to determine distances from object at close
rspelta 3:94aee6f716b7 10 * range. The average range of a sensor is between 0-200mm
rspelta 3:94aee6f716b7 11 *
rspelta 3:94aee6f716b7 12 * In this file are the function prototypes in the VL6180x class
rspelta 3:94aee6f716b7 13 *
rspelta 3:94aee6f716b7 14 * Resources:
rspelta 3:94aee6f716b7 15 * This library uses the Arduino Wire.h to complete I2C transactions.
rspelta 3:94aee6f716b7 16 *
rspelta 3:94aee6f716b7 17 * Development environment specifics:
rspelta 3:94aee6f716b7 18 * IDE: Arduino 1.0.5
rspelta 3:94aee6f716b7 19 * Hardware Platform: Arduino Pro 3.3V/8MHz
rspelta 3:94aee6f716b7 20 * VL6180x Breakout Version: 1.0
rspelta 3:94aee6f716b7 21 *
rspelta 3:94aee6f716b7 22 * Some settings and initial values come from code written by Kris Winer
