I wanted to send about 30 photos from Gallery to PC by selecting them all, clicking Share\Bluetooth and then selecting the target computer.
It didn't work. All transfers failed. But if I selected a single photo I have been able to send it. Around 99MB.
I've been able to workaround by zipping (thanks ES File Manager!) and sharing the zip file only.
Is there something that I should know about sending multiple files via Bluetooth?
