Oh yes, LE is a completely different can of worms (and a horrible one at that). I was referring to classic Bluetooth, since most LE headsets also support it as a connectivity mode.

What are the bandwidth and range for LE in practice?

2Mbits PHY as of 5.0, which in reality means ~175kB/sec across uplink and downlink - maximum. Range is very good, 100-300 feet in open conditions.

Interesting.

I wonder if there's any way for them to increase the bandwidth 10x or so. It would increase the use cases a ton.

btw I hope I didn’t come across snarky. I agree BLE would be better with more bandwidth, I think part of the reason Bluetooth is the F-35 of protocols is it tried to be everything to everyone and it’s a hard line to draw. IMO audio should be in the BLE camp but beyond audio I think wifi is a better fit. JMHO.

I think we call it WiFi ;) but yes I agree, I expect to see incremental bandwidth improvements moving forward.

I don't think there are many devices that can create ad-hoc connections between them using WiFI. Maybe they should, but are there many devices that can do this?

I.e. I connect my Windows laptop to my Android phone directly through WiFI, in a very simple manner.
