I recently had to replace the camera+gimbal on my Phantom Vision 2+, and had trouble getting the new camera's MAC address, so I could rebind it to my controller's range extender. Others have had the same problem - so here's a quick explanation of one way to do this. You may see instructions telling you to scan a QR code that's labeled on the Phantom Vision 2+ packaging, or on the camera itself. That won't work, because although there is a label (with a QR code) on the camera, this label and QR code encodes only the camera's serial number, *not* the camera's MAC address. It should be possible, in principle, to ask DJI to tell you the MAC address for the camera, after telling them the serial number. DJI presumably has a database that allows them to look up properties of the camera (such as its MAC address), given its serial number. However, I had no luck when I asked DJI about this. When I emailed "firstname.lastname@example.org", the responder seemed confused about my question, and eventually gave me the (incorrect) advice to scan a QR code that's on the camera. When I emailed "email@example.com" and "firstname.lastname@example.org", I got no response after at least 24 hours. (Other people, however, have reported having better luck in getting an answer from DJI.) Turn on the Phantom Vision 2+, but *not* the controller's Range Extender. When you power on the Phantom Vision 2+ its camera's WiFi interface starts up by creating a 'hidden' network - i.e., one that does not have an announced network name (SSID). Therefore, most WiFi scans will not see the camera's WiFi interface. Instead, you will need to use a special WiFi scan that reveals hidden networks. For the Mac, some people have reported that the "KisMAC" application will show hidden networks. However, I was *not* able to get this application to see the Phantom Vision 2+'s camera, and to date I do not know of a Mac application that will so this. For Windows, however, I was able to discover the Phantom Vision 2+'s camera by using a Windows XP laptop, and running its normal WiFi scanning tool: Wireless Connection Status -> Find WLAN -> click the "Show Details" checkbox (This may or may not work for computers running newer versions of Windows. Of course, it'll need to have a WiFi interface.) You should see (perhaps after waiting a few seconds) an "open network" with no network name, and a MAC address that begins with 60:60:1F. Then, turn on your controller's Range Extender. (If you're still scanning for WiFi networks, you'll see the Range Extender's WiFi network. This (unlike the camera's hidden WiFi network) will have a name, beginning with "Phantom_".) Then, run the "DJI Vision" app on your smartphone or tablet. Click "Settings", then "Binding". Under "New Camera", you'll see a menu item labeled "MAC Address". Click this, enter the new camera's MAC address, then click the 'tick' box in the upper-right corner to complete the binding. Ross.
