Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

C107 and the codes in its group mean the Nest camera couldn't connect to your phone over Bluetooth during setup. Turn the phone's Bluetooth off and on and keep the phone within about 12 inches (0.3 m) of the camera until setup finishes.

Safety first

Stop and check this first

  • Keep the phone close to the camera only during setup; Google doesn't require that distance for normal use.

Safe checks you can perform

  • Restart camera and phone Bluetooth
  • 12 inch distance during setup
  • Another phone or setup without Bluetooth

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Diagnosis with Google Nest support
  • Do not attempt this professional task: Phone check by its repair service

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Diagnosis with Google Nest support

    What they doGoogle support reviews the camera model, codes and phones tried, and confirms whether the camera supports setup without Bluetooth.

    They must show youwhich alternative setup they apply to your model.

    In writingthe case number and conclusion, with the reason if they propose replacing the camera.

  2. Phone check by its repair service

    What they doIf the phone's Bluetooth won't turn on or also fails with other accessories, the phone's repair service checks it.

    They must show youa Bluetooth test of the phone with another accessory.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Restart camera and phone Bluetooth

    No special tools

    Who:
    you.
    How:
    quit the Nest app, restart the camera and on the phone switch Bluetooth off and on again. If it won't turn on, reboot the phone.
    Result that matters:
    Bluetooth on and a new setup attempt.
    If setup completes:
    the phone's Bluetooth was stuck.
    If the code returns:
    bring the phone closer to the camera.
    Evidence to keep:
    note the code and whether Bluetooth turned on normally.

  2. 12 inch distance during setup

    No special tools

    Who:
    you.
    How:
    bring the phone within 12 inches (0.3 m) of the camera and keep it there until setup is complete, as Google advises.
    Result that matters:
    whether setup completes with the phone next to the camera.
    If it completes:
    distance or interference was blocking the link.
    If it still fails:
    try another phone.
    Evidence to keep:
    note of the distance used and the result.

  3. Another phone or setup without Bluetooth

    No special tools

    Who:
    you.
    How:
    install the Nest app on another phone and redo setup. If you have Nest Cam Indoor or Nest Cam Outdoor, Google lets you set it up without Bluetooth.
    Result that matters:
    whether the camera is added with another phone or without Bluetooth.
    If it works:
    the fault was the first phone, not the camera.
    If it still fails:
    contact Google support with the codes.
    Evidence to keep:
    model of both phones and the result of each attempt.

What it means

Google groups C107, C111, C201, C234, NC021 and others as a Bluetooth connection problem: the camera couldn't connect to the phone over Bluetooth, which the app uses during setup. Google links the failure to the phone's Bluetooth and to wireless interference, which is why it asks you to bring the phone close to the camera. Nest Cam Indoor and Nest Cam Outdoor can also be set up without Bluetooth. The code does not prove the camera is faulty.
