When the Pi Pico W launched, everyone cheered because it had Wi-Fi 4 built in, but then looked confused because the integrated Bluetooth wasn’t supported. So, it’s time to start cheering again because the latest SDK 1.5.0 provides Bluetooth capabilities. But don’t cheer too much as Bluetooth audio isn’t supported. https://github.com/raspberrypi/pico-sdk
Yay for Bluetooth! Boo for missing Bluetooth audio!
