How to disable Bluetooth of Raspberry Pi from Yocto?

Sourabh Hegde

Hello All,

I have a question regarding disabling bluetooth of my Raspberry Pi Compute Module 4. I know that we need to set "dtoverlay=disable-bt" in config.txt

But how to do it from Yocto? Should I include this in conf/local.conf?

While booting my serial console is stuck here:

OpenEmbedded nodistro.0 raspberrypi4-64 ttyS0

Can anyone please let me know whether disabling Bluetooth will solve this?

Your help will be much appreciated.

Thanks in advance.
