1. A device capability discovery method, comprising:
sending, by a first peer-to-peer (P2P) device supporting wireless fidelity (Wi-Fi) P2P, a probe request frame; and
receiving, by the first P2P device, a probe response frame from a second P2P device, wherein the probe response frame comprises capability information of the second P2P device for a user to select an appropriate device for cooperating with the first P2P device to implement a corresponding function, wherein the capability information includes distributed capability, a shooting capability, a display capability, an audio play capability, and an audio capture capability, wherein the capability information of the second P2P device is used to indicate a capability supported by the second P2P device, and wherein the second P2P device supports the Wi-Fi P2P.
