The Peer to Peer Profile is a Generic Attribute Profile (GATT) based low-energy profile defined by STMicroelectronics with proprietary UUIDs
The Peer to Peer Profile, widely used for direct connection, defines the communication between a GATT-server of a Peer to Peer Server device, and a GATT-client Collector device, such as a smartphone, STM32WBA Peer to Peer Client or Peer to Peer Router devices.
- The Peer to Peer Server:
- Contains the P2P Service, which expose two characteristics (Notification & Write) in order to create a bi-direction data communication.
- Is the GATT server.
- The Collector:
- Accesses the information exposed by Peer to Peer Server, controls it with the Write characteristics, receives Notification from it.
- Is the GATT client.
This wiki page is the description of the Peer to Peer Server and Peer to Peer Client projects provided within the STM32CubeWBA MCU Package[1]
