This morning I was finally able to transfer two files between the Moto Gs Play (sending)/and Pure (receiving). One of them was fairly big. When I tried to send a third file, the Bluetooth option was gone. I made sure it was actually on and went to connections. The Pure showed as an option, but only briefly. Then I went to system settings and cleared Bluetooth cache, but it still didn't work. Should I clear data too, or is something else going on here?
