In this embodiment step 101, the first device establishes a bluetooth low energy BLE connection with the target second device.
First, a first device monitors surrounding BLE broadcast messages to acquire BLE broadcast messages broadcasted by at least one second device.
Determining a BLE broadcast message of the target second device from BLE broadcast messages broadcast by the at least one second device in two ways, respectively by the target wireless AP or the target BLE;
In one mode, a target wireless AP determines:
The first equipment scans accessible wireless APs, the first equipment displays all accessible wireless APs, the displayed content is SSID of all accessible wireless APs, a user determines a target SSID from the displayed SSID, the wireless AP corresponding to the target SSID is the target wireless AP, and the second equipment to which the target wireless AP belongs is the target second equipment.
The first device analyzes all the monitored BLE broadcast messages to obtain the SSID carried in each BLE broadcast message, and the BLE broadcast message to which the SSID consistent with the SSID of the target wireless AP belongs is determined to be the BLE broadcast message of the target second device by comparing the SSID with the SSID of the target wireless AP obtained by the first device in a scanning way.
Mode two, determine with target BLE:
The first device scans accessible BLE, the first device displays all accessible BLE, the displayed content is UUIDs of all accessible BLE, the user determines a target UUID from the displayed UUIDs, BLE corresponding to the target UUID is the target BLE, and the second device to which the target BLE belongs is the target second device.
The first device analyzes all monitored BLE broadcast messages to obtain UUIDs of the BLEs carried in each BLE broadcast message, and determines the BLE broadcast message of the target second device by comparing the UUIDs with the UUIDs of the target BLEs obtained by the first device in a scanning manner, wherein the BLE broadcast message of the UUID consistent with the UUIDs of the target BLEs belongs to the BLE broadcast message.
After the first device determines a BLE broadcast message of the target second device through the target wireless AP and the target BLE, a BLE connection request is sent to the second device based on the BLE broadcast message so as to request to establish BLE connection with the target second device.
In steps 102-104 of this embodiment, there are two ways to establish a wireless AP connection between a first device and a target second device:
Mode one:
The first device analyzes the BLE broadcast message of the target second device to judge whether the BLE broadcast message carries information which characterizes that the wireless AP established by the target second device supports working in the 5Ghz frequency band, if yes, the first device sends a first BLE request message to the target second device through the established BLE connection, and the first BLE request message is used for requesting the target second device to switch the working frequency band of the wireless AP (namely the target wireless AP) from 2.4Ghz to 5Ghz.
It should be noted that, if the first device does not support 5Ghz, the procedure of this embodiment does not need to be executed, and the target second device is directly accessed according to the existing wireless AP access mode of 2.4 Ghz.
After the target wireless AP frequency band is switched, the target second device informs the first device to read the first BLE response message through the API interface.
The first device reads a first BLE response message generated by the target second device through the BLE connection.
The first BLE response message carries an SSID and a password of the target wireless AP.
Judging whether BLE broadcast information carries information representing that the wireless AP established by the target second equipment supports working in the 5Ghz frequency band or not, and if not, judging whether the information is carried by the BLE broadcast information. The first equipment analyzes the BLE broadcast message of the target second equipment and judges whether the SSID and the password carried by the BLE broadcast message are complete;
If the result is yes, the SSID and the password carried in the BLE broadcast message of the target second device are judged to be complete, and the first device accesses the wireless AP through the SSID and the password carried in the BLE broadcast message of the target second device.

And the target second equipment receives the second BLE request message sent by the first equipment, generates a second BLE response message, and informs the first equipment to read the second BLE response message through the API interface, wherein the second BLE response message carries the SSID and the password of the target wireless AP.
The first device reads a second BLE response message to the target second device through BLE connection, and accesses the target wireless AP according to the SSID and the password carried in the second BLE response message.
In addition, whether the BLE broadcast message carries information representing that the wireless AP established by the target second equipment supports working in the 5Ghz frequency band is judged, if the judging result is negative, the SSID and the password of the target wireless AP can be obtained by reading the two-dimensional code, identifying the Bluetooth name, connecting the server and other methods, and the obtained SSID and password can be accessed into the wireless AP of the target second equipment.
Mode two:
The first equipment sends a third BLE request message to the target second equipment through BLE connection, wherein the third BLE request message carries information representing whether the first equipment supports a 5Ghz frequency band or not;

And when the target second equipment determines that the first equipment supports the 5Ghz frequency band according to the received third BLE request message, switching the working frequency band of the wireless AP established by the target second equipment to the 5Ghz frequency band.
And after the target second equipment completes the switching, generating a third BLE response message through BLE connection, and informing the first equipment to read the third BLE response message through an API interface. The third BLE response message carries an SSID and a password of the wireless AP. The first device reads the third BLE response message through BLE connection, and accesses the wireless AP according to the SSID and the password carried in the third BLE response message.
If the target second device determines that the first device does not support the 5Ghz frequency band according to the received third BLE request message, the target second device generates a fourth BLE response message and informs the first device to read the fourth BLE response message through an API interface, the first device reads the fourth BLE response message through BLE connection, the fourth BLE response message carries the SSID and the password of the wireless AP, and the working frequency band of the wireless AP is 2.4Ghz. And the first equipment accesses the wireless AP according to the SSID and the password carried in the fourth BLE response message.
If the target second device does not support the 5Ghz band, then:
After receiving the third BLE request message of the first device, the target second device sends a response message to the first device, wherein the response message carries the SSID and the password of the wireless AP, and the working frequency band of the wireless AP is 2.4Ghz.
