My biggest problem with Bluetooth is never having a good way to figure out why something's not working right. For example, one time I wanted to transfer photos from a phone to a tablet with no internet. With one on BT 3 and one on BT 4, the theoretical speed should've been 20mbps. Instead it was around 50KB/s. Why? Who knows. My crappy eight year old bluetooth receiver, while not having quite the audio quality of my newer headphones, has zero perceptible latency. My newer headphones are practically useless for gaming but if I try to use the headset profile the quality is so low as to be worthless for anything but phone calls. How is the old one doing it better? I have no idea.

Since EDR (BT 2.1) added 3Mbps, no faster modulations were added. And that is raw rate without framing or protocol. BT3.0 added ability to offload actual xfer to another protocol (like wifi) but nobody implements this BT4.0 just added LE (another modulation, another set of protocols) at 1 Mbps BT4.2 added a faster rate of 2Mbps for LE Source: a full-blown case of PTSD from working on BT for years
