Ditto.
BT is a consumer convenience meant for home or office use. It PUSHES a signal to your audio device which is
presumed to be on your desk, in your car, or on the kitchen counter. It follows human nature and people listening to music or podcasts aren't expected to roam more than a few meters away from the payback device. More often than not, people use earbuds, but Bluetooth is for a
shared listening experience or where you're not allowed to cover your ears - such as in the car or at work.
If you seek out user reviews - even professional products from names like
Radial Engineering reveal the same level of frustration even when the linked device is in immediate proximity to the console. If I had to make a BT connection available at a corporate event, I would place the BT-DI at the location of the device. This is likely to be the podium or stage seat from which the person with the device is presenting. Thus, the link is short and immediately converted to balanced analog audio that can be routed through a snake or stage box.
For a DJ event, if you want to be able to use BT from the cake table or other location away from your DJ rig - you are going to have to do the same thing. During setup, run an XLR line to a location at or near where you intend to be and use a BT receiver that can run on phantom power (
Switchcraft Stix) sending analog audio back to your mixer.
As a general rule, if I'm using a device at the console it's line powered and hard wired. There's no reason for it not to be. For the most part - lightning connectors suck. They're Apple's contribution to gaff tape sales.
