The question about receiving files through bluetooth

Hi,

I know bt on tx2 works in the order:connect-send files-disconnect.
And it is about sending files from tx2 to my phone. It works well.

Then I try to send files from my phone to tx2.
It is failed. My phone shows “Unable to send files”, although I try different formats of files.
Meanwhile, it is strange that I found tx2 GUI shows bt works in the order:connect-disconnect although it isn’t sending files.

So I don’t know whether the function about receiving files through bluetooth is disabled by kernal or config.
Or it whether is unsupported.

Thanks.
