Is the radio module on by default?

Hi guys!

Just wondering if the radio module on the Verdin imx8mm is on by default even though no antenna is connected? I am asking since we are about to do EMC tests on our board and we have no easy way of verifying if there is anything happening on the module by default.

Hello, the power to the Radio module you see on top is always there.
But there is a way to put it on standby.
I am waiting for feedback on this from R&D and get back to you.

Best Regards,


hello check the comand “rfkill”

Thank you friend!

Unblocked means that it is activated and possible to use I assume?

Yes, that is my understanding.
