Your article is great, too! I've saved it along with other Bluetooth resources for reference. Way more accessible than a video, thanks for posting it. There was nothing like it when I was deep in needing to maximize throughput.
The thing I really appreciated in the presentation was the visualization of how each of the options increased throughput. I also was very thankful that CoreBluetooth handles so much for us. I was able to get our firmware updates to get to 85% theoretical speeds without having to do much fiddling (besides good algorithm design).
I am jealous of your lab gear, though. I got Ubertooth [0] running for sniffing, but could only successfully follow a connection event about 25-33% of the time.
