Interactive commands for WPA_CLI and wpa_supplicant

1) through the ADB command line, you can open the supplicant directly, thus running WPA_CLI, can solve the customer does not have the display and unable to operate the WiFi problem, but also to avoid the problem of the UI to driver. Further, it can be used in many Android terminal products without keyboard input and LCD output.

The wpa_supplicant contains two main executable tools: Wpa_supplicant and WPA_CLI. Wpa_supplicant is the core program, and its relationship with WPA_CLI is the relationship between service and client: Run Wpa_supplicant in the background, use WPA_CLI to search, set up, and connect to the network.

(2) A number of commands can be executed in WPA_CLI interactive mode, with the following list:

Full command	Short command	Description
Status	Stat	Displays the current connection status
Disconnect	Disc	Prevents Wpa_supplicant from connecting to an access point
Quit	Q	Exits WPA_CLI
Terminate	Term	Kills Wpa_supplicant
Reconfigure	Recon	Reloads wpa_supplicant with the configuration file supplied (-c parameter)
Scan	Scan	Scans for available access points (only scans it, doesn ' t display anything)
Scan_result	Scan_r	Displays the results of the last scan
List_networks	List_n	Displays a list of configured networks and their status (active or not, enabled or disabled)
Select_network	Select_n	Select a network among those defined to initiate a connection (ie Select_network 0)
Enable_network	Enable_n	Makes a configured network available for selection (ie enable_network 0)
Disable_network	Disable_n	Makes a configured network unavailable for selection (ie disable_network 0)
Remove_network	Remove_n	Removes a network and its configuration from the list (ie Remove_network 0)
Add_network	Add_n	Adds a new network to the list. Its ID'll be created automatically
Set_network	Set_n	Shows a very short list of available options to configure a network when supplied with no parameters. See next sections for a list of extremely useful parameters to is used with Set_network and get_network.
Get_network	Get_n	Displays the required parameter for the specified network. See next sections for a list of parameters
Save_config	Save_c	Saves the configuration

(3) Platform Operation Example (MTK platform and root permission only)

A, first ensure that the ADB is connected, and can run ADB remount, so as to avoid system files read-only. Then set WPA_CLI and Wpa_supplicant to have strong permissions.

B, run echo 1 >/dev/wmtwifi to start the WiFi drive. But this can not be shown on the Android interface, the default is to start the WiFi module on Android, that is, the setting of WiFi in the default on.

C, enter the/system/bin directory, first run the service-side wpa_supplicant.

./wpa_supplicant-iwlan0-dnl80211-c/system/etc/wifi/wpa_supplicant.conf

The echo after normal startup is as follows:

A non-revenue state indicates that the server is already running (or possibly an input state, as long as the Wpa_cali can be connected on the line). The parameter meaning of-i-d-C can be queried directly in Help, some parameters may differ depending on the platform.

D, open an adb SHELL and run Wpa_cali on the client side. As follows:

Cd/system/bin

Wpa_cli-p/data/misc/wpa_supplicant

echo the following instructions are normal and in interactive mode:

E, execute a series of commands to see

Scan

Scan_results

F, even the WiFi command line, there are the following:

For APs that doesn ' t has encryption
>add_network (It would display a network ID for you, assume it returns 0)
>set_network 0 SSID "666"
>set_network 0 Key_mgmt NONE
>enable_network 0
>quit


For APS that have WEP
>add_network (assume returns 1)
>set_network 1 SSID "666"
>set_network 1 Key_mgmt NONE
>set_network 1 Wep_key0 "Your AP Passwork" (If usting ASCII, it need
Double quotation marks, if using hex, then don ' t need the double quotation
Marks
>set_network 1 Wep_tx_keyidx 0
>select_network 1 (optional, remember, if you is connecting with another
AP, should select it to disable the another)
>enable_network 1

For APS that have WPA-PSK/WPA2-PSK
>add_network (assume returns 2)
>set_network 2 SSID "666"
>set_network 2 PSK "Your pre-shared Key"
>select_network 2 (optional, remember, if you is connecting with another
AP, should select it to disable the another)
>enable_network 2

My own experimental diagram is as follows:

The above process shows that networking OK, you can surf the Internet.
