UI control for WiFi. Can't open UI

Part of the main is that you want to know what WiFi as a function, that is, WiFi is only as station function, or to turn on the peer-to function, when the WiFi as station function when the Wpa_supplicant service is opened, when WiFi as peer-to open the function is P2p_ SUPPLICANTF Services.

When the WiFi as station function is turned on is wpa_supplicant, this time generally do not appear interface error, because this time wpa_supplicant service only use Wlan0 interface, The Wlan0 interface is generated by default even if the upper layer does not define the wlan0 underlying driver

When Wi-Fi is turned on as a peer, the interface error may occur because the P2p_supplicant service uses the P2p0 interface, so you need to define the p2p0 in advance p2p_supplicant.

If you do not define the P2p0 interface, but sometimes the P2p_supplicant service is started at the time of loading, because the P2p_supplicant service will use the P2p0 interface, the load failure occurs. So how can you make the system not start the P2p_supplicant service first, but start the Wpa_supplicant service first? This is because your platform/etc/permisssions/directory has android.hardware.wifi.direct.xml this file, as long as the file is deleted or renamed, after the change, remember to reboot to take effect, the operating instructions are as follows:

How do you tell if it's p2p_supplicant or wpa_supplicant? Since you started the P2p_supplicant service without defining p2p0, it is clear that the following log is visible from log:

Wpa_supplicant (4316):p 2p0:failed to initialize driver interface

But why does this problem occur? Delete the file directly also not, the file is peer-to file, deleted there is no direct function.
Later, compare the findings. Some directories are missing.

File Address Device/ti/beaglebonebalck/boardconfig.mk

uses_ti_mac80211: = Truewifi_firmware_loader            : = "" Common_global_cflags + =-duses_ti_mac80211

Then you can add it.
