Tonight, a portion of Google’s long-in-development Fuchsia OS has been listed with the Bluetooth SIG.

In fact, Fuchsia distinctly prides itself on not being based on Linux, unlike Android and Chrome OS.

Tonight, a new listing from Google LLC arrived at the Bluetooth SIG for “Google Sapphire 1.0 Bluetooth Core Host Solution.” We know from past research into Google’s Fuchsia OS that “Sapphire” is the internal codename for Fuchsia’s Bluetooth stack, and Sapphire’s description on the Bluetooth SIG website also calls out Fuchsia specifically.

Having a portion of an operating system arrive at the Bluetooth SIG is actually a fairly common occurrence.

Unfortunately, not much beyond the fact that Fuchsia will support Bluetooth 5.0, which shouldn’t come as a surprise, being the most current version of Bluetooth.

In fact, we already knew that Fuchsia had been demonstrated at a private Bluetooth SIG event back in 2018.

Instead, the better question is why — why has Google put in the effort to get Fuchsia, which still feels like a skunkworks project, certified by the Bluetooth SIG.
