Add support WiFi USB dongle based on rtl8192cu to Android 5.0.2 or 4.4.3

[evgenymolchanov]

Hello all.

I really need add support WiFi USB dongle based on Realtek rtl8192cu chip to my custom board with iMX6Q based on sabresd.

I have download Realtek Wi-Fi SDK for Android ICS version 2.3.0. Is it right or not?

It seems what this SDK very old.

Could you provide working tutorial with working wifi_realtek.c, wpa_supplicant, wpa_cli and, BoardConfig.mk and all neded files?

The wifi vendor will provide the pacagke including  to enable the wifi in android.

But you need to tell the vendor exactly the android version you are using.

That's the development flow, you should be aware of that.

I know this, but in Android source tree already presents vendor (Realtek) package.

I didn't yet compare them with files downloaded from vendor.android_L5.0.0_1.0.0-ga_core_source include patches for realtek:

0002-ENGR00235825-1-realtek-wifi-changes-in-hardware-real.patch

0003-ENGR00232913-Wifi-enable-realtek-wifi.patch

0009-MA-5944-Upgrade-Realtek-wpa_supplicant_lib-for-Lolli.patch

but wifi_realtek.c return error then i try compile it.

Have you tested any realtek USB dongle under android 5.0.0?

Should I replace all this files with files provided by vendor?

Hi Evgeny,

The patch for hdmi dongle.

The part of wifi is from realtek.  Realtek provide solution. Freescale just did the integration.

The wifi for Android is not link its in linux, need vendor to provide whole package including framework.

Actuall, the wifi support is not Freescale support scope.

If the interface of usb for wifi has problem, check with Freescale.

If the interface of pcie for wifi has problem, check with Freescale.

If the interface of the SDIO for wifi has problem, check with Freesale.

There are lots of Android questions, please check with Android forum.

Hello Igor.

I have one more question.

I have downloaded patches for HDMI Dongle.

This patches refers to wpa_supplicant_8_rtl.

Where can I found and download latest version of wpa_supplicant_8_rtl?

Cause it is not included in default android source tree and doesn't appear after Freescale c_patch.

From here ?
