Hi bikokeki,
Thanks for visiting the Google Nest Community. Try to do these:
- Reboot your Google Home speaker by unplugging its power cord for a minute. Plug it back in and wait for it to boot up.
- Voice command your Google Home speaker: “Hey Google, connect to Bluetooth.”
- Turn off and on Bluetooth on your Nintendo Switch > Scan new devices > Pair to your Google Home speaker.
Let me know if that helps.
Regards,
Alex
