Wi-Fi & BT support on MCIMX7ULP-EVK (Android BSP)

I have installed Android P9.0.0_2.2.0 BSP from NXP [Link] onto my MCIMX7ULP-EVK board.


When I try to enable Wi-Fi using the Android UI (Settings -> Network & Internet), the slide-bar for enabling Wi-Fi gets activated on click but goes back to deactivated after a few seconds. I don't see any thing related to Wi-Fi being displayed on debug console / adb shell either.


Similarly, when I try to enable Bluetooth, that does not work either. On console I get messages like these:

rfkill: BT RF going to : off
rfkill: BT RF going to : on

This is repeated a few times after with I get "Bluetooth keeps stopping" popup on Android screen.




I am using MCIMX7ULP-EVK without any customisation.

The board has QCA9337 Wi-Fi & BT module present on the SOM.

I went through the Android docs [Link] for this BSP and the only things I could find on Wi-Fi or BT is in the Android_Release_Notes.pdf Page 5: Broadcom BCM43430 for Wi-Fi & BT support for i.MX 7ULP EVKB-SD.

But BCM43430 is not part of the MCIMX7ULP-EVK hardware.

No mention of QCA9337 anywhere in those docs.




Can someone confirm whether Wi-Fi & Bluetooth(QCA9337) support is added in this release of the Android BSP?


Or can some one give some hints as to how I can figure this out myself.

I have tried these rudimentary things already:

evk_7ulp:/ $ lsmod

brcmfmac 245760 0
brcmutil 16384 1 brcmfmac

Please help me with this.


Thanks a lot.
