2.5.2.3 P2P Invitation Procedure - Create Autonomous 1:2 P2P Group, (Push button Control)

The following section details the P2P connection with the PIN method. Below are the general steps:

  1. P2P Invitation Request frame is transmitted by a P2P Group Owner or a P2P Client in that P2P Group.
  2. Upon receiving the P2P Invitation Request, a P2P Device that supports the P2P Invitation Procedure signaling mechanism transmits a P2P Invitation Response frame.
  3. The decision to accept the invitation is left to the invited P2P Device

The Flow of commands shows a case where the EVM#1 is the GO and invites EVM#2.
