Bluetooth operates in an unlicensed band. If any medical device relies on any unlicensed band for any life-critical thing that is horrible design. I would absolutely support consequences to any device manufacturer if a death is caused by a jamming of unlicensed frequencies. (In my opinion, medical devices should be able to keep you alive in any jamming scenario if feasible. But using licensed bands is just bare minim…

How is additional paperwork supposed to help? Jamming is already illegal and usage of ISM bands is quite strictly regulated.

Additional paperwork reduces the likelihood (in actual, observable practice) that unintentional interferers exist to impact your critical-to-life application.

Furthermore, by moving your critical-to-life application away from common frequencies of interest, you avoid being collateral damage to jammers targeting unrelated applications.

How do you _realistically_ get in trouble for using it? Jam 2.4 at an airport or near military base?

This guy was caught for jamming cell phones on his commute to "keep people off their phones". I heard of a similar case of someone doing the same on their bus commute but don't have a link for that handy atm https://www.pcmag.com/news/fla-man-fined-48k-for-jamming-cel...

This took months to investigate and was only detectable because the defendant did it along the same route each day. Random, sporadic jamming is essentially not prosecutable.

What I want is a tiny portable bluetooth jammer for those who insist everyone in public must be listening to their music. Sadly they are too clunky to haul around each day.

If I am not mistaken, this type of jammer can severily affect people with pacemakers. But, as a Brazilian citizen, I can understand the feeling of being forced to listen other's people music.

jamming on 2.4ghz will in no way impact the core function of a pacemaker

yes, the new ones come with BT LE so you can monitor it via your smartphone (yeah really..) but I would not call that 'severely affected'
