BLE_p2pServer Application Description

How to demonstrate Point-to-Point communication using BLE (as GATT server).

p2pServer application advertises and waits for a connection from either:

• p2pClient application running on STM32WBAxx devices
• ST BLE Toolbox smartphone application

Once connected, p2pServer can receive message from the Client and send notification to it.

Hardware and Software environment

• This application runs on STM32WBA55 Nucleo board.
• Another Nucleo board may be necessary to run p2pClient or p2pRouter application.

How to use it?

In order to make the program work, you must do the following :

• Open your preferred toolchain
• Rebuild all files and load your image into target memory
• Run the example

You can interact with p2pServer application with a smartphone:

• Install and launch ST BLE Toolbox application on android or iOS smartphone

  • ST BLE Toolbox Android
  • ST BLE Toolbox iOS

• Open ST BLE Toolbox application: select the P2PS_WBAxx in the device list, where xx is the 2 last digits of the BD ADDRESS.

• On p2pServer device B1 click, a notification message is sent toward connected smartphone.

• On smartphone interface, click on the LED icon to switch On/Off LED1 of the Nucleo board.

Antother possibility is to interact with p2pServer application with another STM32WBA55 Nucleo board:

• Power up p2pClient devices next to p2pServer device.

• On p2pClient device, click on button B1 to launch a scan. A connection is initiated if a p2pServer device is detected.

  • On p2pServer device, click on button B1 to send a notification message toward connected p2pClient device.
  • On p2pClient device, click on button B1, to write a message toward connected p2pServer device.

• Adertising is stopped after 60s, button B1 click allows to restart it.

• When not connected, button B2 click allows to clear security database.

• Once connected, button B3 click allows to update connection interval parameters.

Multi connection support:

• Pressing button B2 while the device is already connected starts a new advertising to allow multi-connection.
