Product overview


FP-NET-BLESTAR1 is an STM32Cube 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 an STM32L4 Discovery Board as a BLE master connected to several BLE peripherals, or nodes, in a star network topology. The BLE central device 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.
