Launch the ShareMe app on your device and select "Receive". The app will ask you to turn on permissions in order for the app to function such as the location and Bluetooth services. Once you've switched them on, select "Next" and a QR Code will be displayed on the next screen. Have the sender open the ShareMe app on their device and select "Send" and grant access permissions for the app and have them scan your QR Code. Once the scan is successful, it will then start sending the file.
