1. Introduction
The STM32CubeWBA MCU Package[1] provides software components running on STM32WBA Series MCUs.
For all examples provided with the package, the following integrated development environments are supported:
- STMicroelectronics integrated development environment for STM32 products (STM32CubeIDE)
- IAR Systems® IAR Embedded Workbench® for Arm® (EWARM)
- Keil® Microcontroller Development Kit (MDK-ARM)
The Firmware Package for the STM32WB series is also available on STM32CubeWBA github[2].
2. STM32WBA Bluetooth® LE software architecture
The STM32WBA Bluetooth® low energy architecture
3. STM32WBA Bluetooth® LE application
The following Bluetooth® LE applications are delivered as source code
| Application | Description | |
|---|---|---|
| Bluetooth® LE SIG | BLE_Beacon | Application advertising different types of beacon: ibeacon, eddystone (tlm, uuid, url) |
| BLE_HealthThermometer | Application supporting the Health Thermometer Sensor as specified by the Bluetooth® SIG | |
| BLE_HeartRate | Application supporting the Heart Rate Sensor as specified by the Bluetooth® SIG | |
| BLE_HeartRate_ThreadX | Application supporting the Heart Rate Sensor with ThreadX implementation | |
| Bluetooth® LE ST proprietary | BLE_p2pServer & Multi Slave BLE_p2pClient | Simple ST proprietary applications to manipulate proprietary Services & Characteristics with single connection or multi slave connections |
| BLE_p2pRouter | ST proprietary application to use the STM32WBA as a GAP Central & Peripheral" and "GATT Client & Server with multi link connection | |
| BLE_DataThroughput | ST proprietary application to measure data throughput between 2 STM32WBA or with the dedicated ST Bluetooth® LE toolbox smartphone application (Android and IOS) | |
| BLE_Fuota (Firmware Update Over The Air) | ST proprietary application to upgrade the STM32WBA firmware | |
| BLE_CableReplacement | ST proprietary application to simulate the previous Bluetooth® protocol "Serial Port Profile". The application is based on L2CAP Connection Oriented Channel (CoC) | |
| BLE_p2pServer_Ext | Application to configure up to 8 advertising extended sets | |
| BLE_p2pClient_Ext | Application to scan the extended advertising frames with extended API’s | |
| BLE_TransparentMode | ST proprietary application to support the Direct Test Mode for RF certification. Standard host controller interface (HCI) and application (vendor) controller interface (ACI) can be sent by means of STM32CubeMonitor-RF |
4. Going further based on available application
| Application | Description | |
|---|---|---|
| Bluetooth® LE Feature | Fast FUOTA | Explanation to support fast firmware upgrade over-the-air |
| Additional Beaconing | Explanation to implement an additional beacon | |
| Advertising Extension | Explanation to implement the extended advertising feature | |
| Bluetooth® LE Mesh | Mesh Sensor Model Client Server example | Explanation and concept regarding the Mesh Sensor Model client requesting information from the sensor model server |
| Mesh Vendor Model example | Explanation and concept regarding the ST proprietary mesh vendor model | |
| Others | Bluetooth® LE & Arduino | Explanation and concept regarding the Bluetooth® LE P2P application done with Arduino framework |
