@par Application Description
How to demonstrate Point-to-Point communication using BLE component (as GATT client).
Two STM32WB15xx boards are used, one acting as GATT client, and one as GATT server.
For example, BLE_P2PClient application is downloaded in a Nucleo board (MB1641) and BLE_p2pServer_ota application in a Nucleo board (MB1641).
The client could be located in a phone also, using the ST BLE Sensor application instead of the MB1641 board.
@par Keywords
Connectivity, BLE, IPCC, HSEM, RTC, UART, PWR, BLE protocol, BLE pairing, BLE profile, Dual core

@par Hardware and Software environment
- This example runs on STM32WB15xx devices.
- This example has been tested with an STMicroelectronics STM32WB15CC-Nucleo
board and can be easily tailored to any other supported device
and development board.
- Nucleo board (MB1641) 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 requires having the stm32wb15_BLE_Stack_full_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
- OR use the BLE_p2pClient_reference.hex from Binary directory
- This must be done for BLE_p2pServer and BLE_p2pClient.
- BLE_p2pServer may be connected by BLE_p2pClient.
- Once the code (BLE_p2pServer & BLE_p2pClient) is downloaded into the two STM32WB15xx 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)
- 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 MB1641. 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 MB1641, 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.
