I´ve connected hue esssentials with my android phone and my hue bloom bluetooth was synced. Everything works. But with my Nvidia Shield and Fire TV Cube the connection to my hue bloom via bluetooth does not work. Description says just to switch off and on the light, but this does not work.
Could you switch off your Hue bloom for at least 10 seconds and try again? Please also make sure you are using the latest version of Hue Essentials as there were some improvements for Hue Bluetooth, see: Philips Hue Lightstrip Plus not connecting over Bluetooth
Sorry for the delay, there are lots of support questions at the moment.
