There was nearly a two-year gap between Bluetooth 2.1 and 3.0, with the latter being adopted by the SIG in April 2009. Where EDR was the main draw to the 2.0 and 2.1 days, Bluetooth 3.0's claim to fame was its HS — high-speed channel.
In theory, Bluetooth 3.0 could achieve data transfer speeds up to a whopping 24/Mbs. However, those speeds didn't happen solely over Bluetooth. Instead, Bluetooth 3.0 established a link connection to the 802.11 protocol (AKA, Wi-Fi).
With such vastly-improved speeds, Bluetooth was finally ready to go beyond audio transfers. Now, it was fast enough to stream video wirelessly between devices.
This is one of the biggest speed bumps Bluetooth has ever seen, and it was also the last iteration of the wireless standard before we were introduced to the world of Bluetooth Low Energy.
Really looking this series - a massive improvement on all the Disney+ articles the site has been buried under recently!
