This is a strange one: The 2015 Chromecast, the 2nd generation one that still retails for the same $35 price point it launched with, is going through the US FCC in a recent filing that took place over the weekend.
A little-known fact about the 2015 Chromecast is that it had a Bluetooth chip inside that was never active. Of course, in order to get clearance for any device sold in the US to use Bluetooth, it needs to be filed with the FCC. So Google is filing the Chromecast with the FCC again so that it can use Bluetooth communications.
