There is currently a scanning electron microscope on eBay UK for the incredible bargain price of £470. I do not have space for this.
@ariadne @gedvondur in my experience (which is mostly only using bluetooth audio/A2DP):
so I would recommend something intel (unless you care about not loading non-free firmware, in which case I’ve heard CSR8510 is good even though I’ve never used it myself and the aforementioned broadcom thing that I forgot the name of worked without loading any firmware too)
