BBB Wireless disabling HDMI in uEnv.txt WITHOUT losing bluetooth or wifi functions???

[evangr...@gmail.com]

Hello,

I'm trying to use a beaglebone black wireless to perform simple output tasks and read several sensors continuously while transmitting the information wirelessly. But to do what I need it to do I HAVE to disable the BBB HDMI, that's not a problem, I found out how to do this with uEnv.txt and there is lot's of good documentation, but when I disable the HDMI by modifying uEnv.txt the wireless functionality of the BBB wireless completely disappears :0 no wifi, no bluetooth, no nothing but ethernet connection. There must be a way to disable HDMI without disabling the wireless functions. PLEASE help me! 

Thank you for reading

You have to use u-boot overlays to achieve this:

wifi/hdmi/audio/etc are all separated...
