Hi, asprasan! How are you? I see you're having problems with bluetooth connectivity from/to Firefox OS. I also faced this issue, and now I'm here to help you! Just follow these steps: 1. First of all, make sure your device is paired with your computer. 2. On the Start menu, click "Devices and printers". 3. Find your cellphone there and double-click it. 4. On Authorization options, check "Always allow this device to connect for all operations" 5. Click "Apply" and "OK". You should see a new Bluetooth icon on your systray. RIght click it and open Bluetooth settings. 6. On "Share" tab, check "Allow remote devices to browse, send and receive pictures, music and other files" 7. On the "PIM Interface" tab, check "Allow bluetooth devices to send you PIM items" Try sending a file from your device to your computer and let us know if it worked! '''Note:''' If you're a Linux user, that's a lot easier! On your main menu, search for "Personal File Sharing", or open terminal and type: ''gnome-file-share-properties'' Check "Receive files in Downloads folder over Bluetooth". It shall work now.
