Embodiment one

Please refer to FIG. 1 , which shows a method for automatically connecting to a WIFI hotspot provided by an embodiment of the present invention.

The method for automatically connecting to a WIFI hotspot is applied in a mobile terminal, and specifically includes the following steps:

In step S101, open the NFC function of the mobile terminal;

In the embodiment of the present invention, the MAC address of the WIFI hotspot and the WIFI password are made on the NFC barcode in advance. When the mobile terminal user needs to connect to the WIFI network, as long as the NFC function of the mobile terminal is turned on, the NFC barcode can be scanned by the mobile terminal with the NFC function, and the WIFI hotspot corresponding to the MAC address can be automatically connected, so that the WIFI hotspot can be connected to the WIFI hotspot. The WIFI password is verified and connected to the WIFI network.

However, it can be understood that the user may manually enable the NFC function of the mobile terminal, or the mobile terminal may automatically enable the NFC function of the mobile terminal. The specific implementation scheme for the mobile terminal to automatically enable the NFC function of the mobile terminal is as follows:

1. Detect whether there is a WIFI signal in the current environment.

2. If it is detected that there is a WIFI signal in the current environment, an NFC function activation instruction is generated. If no WIFI signal is detected, the NFC function of the mobile terminal is not enabled.

3. According to the NFC function enabling instruction, enable the NFC function of the mobile terminal.

As a preferred embodiment of the present invention, it is detected whether there is a WIFI signal in the current environment. If it is detected that the current environment has a WIFI signal, and the WIFI signal strength is greater than the preset signal strength value (indicating that the WIFI signal strength is suitable for communication), then Triggering and generating an NFC function enabling instruction, and enabling the NFC function of the mobile terminal according to the NFC function enabling instruction. Otherwise, the NFC function of the mobile terminal is not enabled.

As another preferred embodiment of the present invention, after the step of enabling the NFC function of the mobile terminal, it further includes: prompting the user of the mobile terminal to scan the NFC barcode. The mobile terminal user can be prompted to scan the NFC barcode in the form of voice broadcast. Or, pop up a prompt box to prompt the mobile terminal user to scan the NFC barcode. However, it is not limited to the above scheme.

In step S102, scan the NFC barcode to obtain the MAC address and the WIFI password of the WIFI hotspot; wherein, the NFC barcode includes the MAC address and the WIFI password of the WIFI hotspot;

In the embodiment of the present invention, the NFC barcode is scanned by the NFC read-write module of the mobile terminal with NFC function to obtain the MAC address of the WIFI hotspot and the WIFI password.

In step S103, a WIFI connection instruction is generated according to the MAC address of the WIFI hotspot and the WIFI password; wherein, the WIFI connection instruction carries the MAC address and the WIFI password of the WIFI hotspot;

In the embodiment of the present invention, the step of generating a WIFI connection instruction according to the MAC address of the WIFI hotspot and the WIFI password specifically includes:

Among them, the class used to scan WiFi hotspots in the mobile phone is called to obtain connectable WiFi hotspots. The specific implementation is as follows:

When WifiSettings and WifiEnabler are created, they will register with Android to receive WIFI_STATE_CHANGED_ACTION, so they will all receive the Intent of WIFI_STATE_CHANGED_ACTION. WifiEnabler is responsible for making the icon brighter, and WifiSettings is responsible for enabling the scanning of WiFi hotspots. Via the startScan of WifiService, and then send the scan command to wpa_supplicant by the android_net_wifi_scanCommand function through JNI. When wpa_supplicant finishes processing the SCAN command, it will send an event to the control channel to notify the scan completion, so that the wifi_wait_for_event function will receive the event, so the WifiMonitor MonitorThread will be implemented to handle incoming scan result events. This thread broadcasts the SCAN_RESULTS_AVAILABLE_ACTION Intent via WifiStateTracker. WifiSettings registers to receive this Intent, and finally its corresponding function updateAccessPoints lists the list of WiFi hotspots in the form of GUI (Graphical User Interface, Graphical User Interface).

In step S203, if it is detected that there is a WIFI signal in the current environment, an NFC function activation instruction is generated.

In step S204, the NFC function of the mobile phone is enabled according to the NFC function activation instruction.

In step S205, the mobile phone prompts the mobile phone user to scan the NFC barcode through a voice broadcast.

In step S206, communicate with the NFC barcode through the NFC antenna coil of the mobile phone to obtain the MAC address of the WIFI hotspot and the WIFI password.

In step S207, the mobile phone configures parameters corresponding to the WIFI hotspot on the mobile phone according to the MAC address of the WIFI hotspot and the WIFI password.

After configuring the parameters corresponding to the WIFI hotspot, the onClick function will be called.

In step S209, the WIFI hotspot corresponding to the MAC address is automatically connected according to the WIFI connection instruction.

Among them, the connect function of Settings responds to the connection, updates the network save configuration, and updates the current selection with the highest priority and saves it. Then use enableNetwork to make other networks unavailable for connection. Finally, call the reconnect function of WifiManager to connect to the currently selected network. The reconnect function of WifiManager calls the reconnect function of WifiService through the Binder mechanism of AIDL. Then the reconnectCommand function of WifiStateTracker will be called, and the RECONNECT command will be sent to WPA_WPASUPPLICANT through the android_net_wifi_reconnectCommand function of JNI (android_net_wifi_Wifi). android_net_wifi_Wifi calls the wifi_command function in wifi.c through doCommand (command name, response buffer, response buffer size) to send commands. Finally, the connection command is sent to the control channel through the wpa_ctrl_request function of wpa_ctrl.

In step S210, after receiving the WIFI connection instruction, the WIFI hotspot verifies the WIFI password, and if the verification is successful, establishes a connection between the mobile phone and the WIFI hotspot, so that the mobile phone can access the WIFI network.

As can be seen from the above, the method for automatically connecting to the WIFI hotspot provided by the second embodiment is to make the MAC address of the WIFI hotspot and the WIFI password on the NFC barcode. When the mobile phone detects that there is a WIFI signal in the current environment, it will trigger the NFC function of the mobile phone. , and then prompt the user to scan that NFC barcode.
