establishing, by the smart terminal according to the device information, a wireless connection with the smart device at the wireless working frequency band at which the P2P data packet is received;
analyzing, by the smart terminal, the P2P data packet and obtaining identification information of a P2P group; and
when the operation to connect to the smart device is detected, joining, by the smart terminal, the P2P group according to the device information and the identification information of the P2P group,
wherein the smart terminal is a terminal supporting a Wireless Fidelity Peer to Peer (WiFi P2P) protocol, and the smart device is a device supporting the WiFi P2P protocol.

2. The method according to claim 1 , further comprising:
adding, by the smart terminal, the smart device into a P2P device list according to the device information; and
when an operation to connect to the smart device is detected, establishing, by the smart terminal according to the device information, the wireless connection with the smart device at the wireless working frequency band at which the P2P data packet is received.

3. The method according to claim 1 , wherein monitoring the plurality of wireless working frequency bands supported by the smart terminal comprises:
when an operation for turning on a P2P discovery function is detected, acquiring, by the smart terminal, a wireless frequency band list, the wireless frequency band list including the plurality of wireless working frequency bands supported by the smart terminal; and
monitoring, by the smart terminal, each of the wireless working frequency bands in the wireless frequency band list to acquire the P2P data packet.

4. A smart terminal, comprising:
a processor; and
a memory configured to store instructions executable by the processor,
wherein the processor is configured:
monitor a plurality of wireless working frequency bands supported by the smart terminal;
when a Peer to Peer (P2P) data packet broadcasted by a smart device is received at a wireless working frequency band of the plurality of wireless working frequency bands, analyze the P2P data packet and obtain device information of the smart device;
establish, according to the device information, a wireless connection with the smart device at the wireless working frequency band at which the P2P data packet is received;
analyze the P2P data packet and obtain identification information of a P2P group; and
when the operation to connect to the smart device is detected, join the P2P group according to the device information and the identification information of the P2P group,
wherein the smart terminal is a terminal supporting a Wireless Fidelity Peer to Peer (WiFi P2P) protocol, and the smart device is a device supporting the WiFi P2P protocol.

5. The smart terminal according to claim 4 , wherein the processor is further configured to:
add the smart device into a P2P device list according to the device information; and
when an operation to connect to the smart device is detected, establish, according to the device information, the wireless connection with the smart device at the wireless working frequency band at which the P2P data packet is received.

6. The smart terminal according to claim 4 , wherein the processor is further configured to:
when an operation for turning on a P2P discovery function is detected, acquire a wireless frequency band list, the wireless frequency band list including the plurality of wireless working frequency bands supported by the smart terminal; and
monitor each of the wireless working frequency bands in the wireless frequency band list to acquire the P2P data packet.

7. A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a smart terminal, cause the smart terminal to perform a method for establishing a wireless connection, the method comprising:
monitoring a plurality of wireless working frequency bands supported by the smart terminal;
when a Peer to Peer (P2P) data packet broadcasted by a smart device is received at a wireless working frequency band of the plurality of wireless working frequency bands, analyzing the P2P data packet and obtaining device information of the smart device;
establishing, according to the device information, a wireless connection with the smart device at the wireless working frequency band at which the P2P data packet is received;
analyzing the P2P data packet and obtaining identification information of a P2P group; and
when the operation to connect to the smart device is detected, joining the P2P group according to the device information and the identification information of the P2P group,
wherein the smart terminal is a terminal supporting a Wireless Fidelity Peer to Peer (WiFi P2P) protocol, and the smart device is a device supporting the WiFi P2P protocol.
