STM32 ODE function pack for creating a BLE star network connected via Wi-Fi to IBM Watson IoT cloud

FP-NET-BLESTAR1 is an STM32 ODE function pack which lets you connect your IoT node in a BLE sensor network to the Internet via a Wi-Fi network. Sensor data from a device in the BLE star network can be transparently sent to the IBM Watson IoT cloud platform and visualized on a client connected to the cloud.

The software, together with the suggested combination of STM32 and ST devices, can be used, for example, to develop smart home or remote monitoring applications. The included sample application configures the STM32 Nucleo board equipped with the Wi-Fi and BLE expansion boards as a BLE master connected to several BLE peripherals, or nodes, in a star network topology. The STM32 Nucleo board can simultaneously connect to a Wi-Fi network and export data from other nodes to the IBM Watson IoT cloud platform. The BLE master also acts as a slave by accepting connection with a BLE client (typically an Android™/iOS™ device) which can be used to monitor and control the BLE network.

The software runs on the STM32 microcontroller and includes drivers to exploit the functionality of the X-NUCLEO-IDB05A1 Bluetooth low energy expansion board based on the SPBTLE-RF module, and the X-NUCLEO-IDW01M1 Wi-Fi expansion board based on the SPWF01SA module.

Key Features

  • Complete firmware to build applications based on BLE and Wi-Fi connectivity, allowing STM32 Nucleo boards to connect with both BLE-enabled smartphones and tablets, and cloud-based services
  • Integrated MQTT protocol middleware for easy access to Watson IoT cloud services provided by IBM
  • Sample application for NUCLEO-F401RE, which behaves simultaneously as master and slave, with X-NUCLEO-IDB05A1 and X-NUCLEO-IDW01M1 expansion boards
  • Compatible with BLE sensor nodes implemented using the FP-SNS-ALLMEMS1, FP-SNS-FLIGHT1 and FP-SNS-MOTENV1 function packs
  • Compatible with the SensNet application for AndroidTM /iOSTM devices to control the BLE star network and to display the data sent by the slave nodes
  • Easy portability across different MCU families, thanks to STM32Cube
  • Free, user-friendly license terms
