I'm having either the same issue or a similar issue. But what's happening on my end is I connect my PC Opera browser to my phone I can send for my PC to my phone but as soon as it try to send anything from my phone it immediately disconnects from my phone and acts as if I'm not connected to anything but when I try to add the device back it says it's already connected and when I go in to connections it show as connected and when I forget the connection I can reconnect my phone but I does the same thing where I can send from my PC but I can receive and if I try to send anything it acts like I disconnected it.
