Hey Sschmad,


I’m sorry for the trouble this has caused you, let me help you out. These errors mean your camera couldn’t connect to your phone through Bluetooth. You’ll need to make sure Bluetooth is working and is enabled on your device. Try these steps and let us know how it goes.


  1. Quit the Nest app.
  2. Use the instructions in this article to restart your camera.
  3. On your phone, switch Bluetooth off and then on again to reset the connection. Make sure that Bluetooth is on when you’re done.
  4. On rare occasions, your phone might not let you turn on Bluetooth. If you run into this issue, try to reboot your device. Otherwise, skip to the next step.
  5. After turning on Bluetooth, bring your phone within 12 inches (0.3 m) of your camera, and keep it there until setup is complete to help reduce wireless interference that may disrupt the Bluetooth connection.
  6. Now, try to set up your camera again.
  7. If you still can’t set up your camera, try a different phone if you have one.
  8. If the Nest app displays a Bluetooth error again, reboot your phone if you haven’t already. Then try to set up your camera again.
