@par Application Description
This example is to demonstrate Point-to-Point communication using BLE component.
Two STM32WB55xx boards are used, one acting as GATT client, and one as GATT server.
For example, BLE P2P_Client application is downloaded in a USB DONGLE board (MB1293C) and BLE_p2pServer_ota application in a Nucleo board (MB1355C).
The client could be located in a phone also, using the ST BLE Sensor application instead of the MB1293C board.
@note This application is not supported by CubeMx but has been copied from the project BLE_p2pServer generated
by CubeMx with some modifications in order to be able to download it with the BLE_Ota application.
The steps to be done to move from the BLE_p2pServer application to the BLE_p2pServer_ota application are :
- Copy the full folder BLE_p2pServer
- Replace the linker file stm32wb55xx_flash_cm4.icf by stm32wb55xx_flash_cm4_ota.icf ( this adds the placement
of the two sections TAG_OTA_START and TAG_OTA_END ).
- Remove the update of SCB->VTOR in the file system_stm32wbxx.c ( The VTOR is already set by the BLE_Ota application
and shall not be changed to a different value)
- set BLE_CFG_OTA_REBOOT_CHAR to 1 in ble_conf.h

@par Hardware and Software environment
- This application runs on STM32WB55xx devices, USB DONGLE board (MB1293C) & Nucleo board (MB1355C)
- USB DONGLE board (MB1293C) Set-up
- Connect the USB DONGLE boards to your PC
- Connect external ST-LINK to dedicated ST LINK Pin
- Nucleo board (MB1355C) Set-up
- Connect the Nucleo Board to your PC with a USB cable type A to mini-B to ST-LINK connector (USB_STLINK).
- Please ensure that the ST-LINK connectors and jumpers are fitted.
@par How to use it ?
This application requests having the stm32wb5x_BLE_Stack_fw.bin binary flashed on the Wireless Coprocessor.
If it is not the case, you need to use STM32CubeProgrammer to load the appropriate binary.
All available binaries are located under /Projects/STM32_Copro_Wireless_Binaries directory.
Refer to UM2237 to learn how to use/install STM32CubeProgrammer.
Refer to /Projects/STM32_Copro_Wireless_Binaries/ReleaseNote.html for the detailed procedure to change the
Wireless Coprocessor binary.
In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load the image into Target memory
[Warning: not use CMSIS startup_stm32wb55xx_cm4.s to compile under Keil toolchain as specific
DCD offset added for OTA application]
- OR use the BLE_p2pServer_ota_reference.bin from Binary directory
- to be flashed at 0x0800 7000
- This must be done for BLE_p2pServer (MB1355C & MB1293C)
First demonstration
On the android/ios device, enable the Bluetooth communications, and if not done before,
- Install the ST BLE Profile application on the android device
https://play.google.com/store/apps/details?id=com.stm.bluetoothlevalidation&hl=en
https://itunes.apple.com/fr/App/st-ble-profile/id1081331769?mt=8
- Install the ST BLE Sensor application on the ios/android device
https://play.google.com/store/apps/details?id=com.st.bluems
https://itunes.apple.com/us/App/st-bluems/id993670214?mt=8
- Power on the Nucleo board with the BLE_P2P_Server application
- Then, click on the App icon, ST BLE Sensor (android device)
- connect to the device
- select the P2PSRVx in the device list and play with the Light and the SW1 button of the board
Second demonstration
- BLE_p2pServer may be connected by BLE_p2pClient.
- Once the code (BLE_p2pServer & BLE_p2pClient) is downloaded into the two STM32WB55xx boards and executed, the modules are initialized.
- The Peripheral device (BLE_p2pServer) starts advertising (during 1 minute), the green led blinks for each advertising event.
- The Central device (BLE_p2pClient) starts scanning when pressing the User button (SW1) on the USB Dongle board.
- BLE_p2pClient blue led becomes on.
- Scan req takes about 5 seconds.
- Make sure BLE_p2pServer advertises, if not press reset button or switch off/on to restart advertising.
- Then, it automatically connects to the BLE_p2pServer.
- Blue led turns off and green led starts blinking as on the MB1355C. Connection is done.
- When pressing SW1 on a board, the blue led toggles on the other one.
- The SW1 button can be pressed independently on the GATT Client or on the GATT Server.
- When the server is located on a MB1355C, the connection interval can be modified from 50ms to 1s and vice-versa using SW2.
- The green led on the 2 boards blinks for each advertising event, it means quickly when 50ms and slowly when 1s.
- Passing from 50ms to 1s is instantaneous, but from 1s to 50ms takes around 10 seconds.
- The SW1 event, switch on/off blue led, depends on the connection Interval event.
- So the delay from SW1 action and blue led change is more or less fast.
Third demonstration
Move to download panel with the smart Phone Application
- select the binary to be downloaded on the Application Processor
- BLE_HeartRate_ota_reference.bin or BLE_p2pServer_ota_reference.bin have to be copied into Smart phone directory
- Start download
- New Application is running and can be connected
