[MCIMX8QM] About WIFI/BT driver in imx-android-11.0.0_2.4.0 SDK

waynejeong — Tue, 16 Nov 2021 05:54:55 GMT

Hello.

I am doing test 88W8997 module made by Laird company using MCIMX8QM.

And SDK is imx-android-11.0.0_2.4.0 (Android 11).

My question is for Bluetooth driver:

I can find the WIFI driver code in /imx-android-11.0.0_2.4.0/android_build/vendor/nxp-opensource/nxp-mwifiex.

In case of the bluetooth driver, is it using the driver in the kernel without a separate release driver code? (path: android_build/vendor/nxp-opensource/kernel_imx/drivers/bluetooth)

Thank you.

Hi igorpadykov

As I know, there is not a prebuilt image in NXP portal, but it's not that it's not supported. I downloaded the SDK and built it myself.

Please see above build number of picture. I took the picture after boot.

Please let me know if i'm wrong.

Question:

When we using NXP WIFI/BT products on Android-11.0.0_2.4.0, are we using the bluetooth driver provided by the Linux kernel? Or is it in a separate directory?

Thank you.

Thank you Igor

Your answer is very helpful for me.

But I have a question more.

I built the mek_8q image following documents Android™ User's Guide (nxp.com).

If it is not supported as you said, what is the SDK version of the image I built?

Dear Igorpadykov

According to Android Quick Start Guide of Android 11.0.0_2.4.0, there is a guide of i.MX 8QuadMax board.

Android™ Quick Start Guide (nxp.com)

Please check once again whether i.MX 8QuadMax does not support android imx-android-11.0.0_2.4.0.

And I'm still building i.mx8qm image inside the imx-android-11.0.0_2.4.0 directory.

Thank you.
