Is syncing via Bluetooth supported? How does it work?
Syncing via Bluetooth is only supported between iOS devices for technical reasons.
To sync your media from one iOS device to another simply enable Bluetooth on both devices and please disable Wi-Fi on one of the devices, because this is the only way to force the devices into a Bluetooth connection. Then start the PhotoSync application on both devices. Now press the red sync button on the device you want to sync media from. It may take a short while until Bluetooth is activated on both iOS devices. Once it is active the Bluetooth icon changes from inactive to active and the other iOS device appears on the device list.
