Continuity camera doesn't work - time out error

I had the same problem, it not only requires you to have bluetooth and wifi on, but i had to go to my bluetooth setting on my computer and select to my phone to connect to via bluetooth. After i paired the iPhone with the computer it works as advertised.

Here's the solution. Given that you satisfy all conditions in this support doc: Use Continuity to connect your Mac, iPhone, iPad, iPod touch, and Apple Watch - Apple Support, then all you have to do is go to your Mac's Bluetooth preferences, and connect the iPhone from the scanned list. You can also do it from your iPhone. Go to Settings -> Bluetooth, connect the Mac from the scanned list. This step about connecting directly between the 2 devices via bluetooth is not mentioned at all in the doc and after doing that, all features of Continuity works. No need to sign out/ sign in iCloud.

Worked for me. Although I had Bluetooth turned on on both devices, I didn't realize that they weren't connected. I went to Settings on my iPad>Bluetooth. Saw my MacBook listed under "My Devices." Tapped on it. A message popped up on my MacBook screen telling me the iPad wanted to connect. I clicked on connect, and that's all there was to it. Continuity camera is now working.

This really a very silly implementation!!!!!!

I had this error . I can make it work only by disconnecting my ethernet cable and linking my Mac and Ipad to the very poor WiFi router signal in my office.

I have ethernet because the office is wired that way and is far better than the building's overloaded router.

This is potentially a very useful feature Apple, which our business could use heavily.

Sadly, we can only use it if we physically disconnect machine and loose reliable connection to our office server.

Major fail Apple!!!!

I used the same method, only I do not have the com.apple.BluetoothFileExchange.plist file.

I deleted com.apple.Bluetooth.plist, restarted everything, and it works!

After following all the suggestions here, nothing worked. I found out that my hard-wired (ethernet cable) iMac wouldn't connect until I also turned on wifi. I usually have wifi turned off because hard-wired is faster on the internet than wifi, but for continuity camera to work, you have to have wifi turned on.

Same here. Changed to wifi and all worked ok.

You also must turn off VPN for this to work!.

Don't forget to check that 2-factor authentication is enabled on your AppleID.

Granted, I have everything enabled and still have the same issue. I guess the next thing to try is signing out of iCloud on all your devices and signing back in. That fixed the iCloud sync issues on many previous macOS continuity features...

once of course everything is updated (iOS12 and Mojave)

in the time honoured way - switch everything off and then switch it all back on again - it should work then

Had same issue .resolved .See below .

Use Continuity to connect your Mac, iPhone, iPad, iPod touch, and Apple Watch - Apple Support

Computer and phone have to be in the same WiFi.

If computer is on cable with wifi down it will not work.

Why Apple, why? Cable connection is still in the same network!

* MacBook Pro 2016 with OS 10.14.1

* iPhone XS Max with OS 12.1

* Both devices have bluetooth enabled, are using the same AppleID, no VPN is enabled and are using the same WiFi network.

* The iOS device is unlocked when starting the process on the MacBook.

Attempted the following:

* Deletion of bluetooth settings on Mac OS

* Disabling and reenabling bluetooth on both devices

* Pairing iOS device with MacBook via Bluetooth

* Simple shutdown / restart of both devices

* Reset of PRAM and SMC on Mac OS

* Hard reset of iOS device

* Reset of Network settings on the iOS device

NB. AirDrop works between the devices, as does sharing of Bluetooth network etc.

In all scenarios above, the same "Device timed out error" is returned when attempting to 'Take photo' or 'Scan Documents'.

So, nothing's worked for me so far...

I've the same problem with my iPhone X.
