Problem sending file using Google Nearby Connections on specific device

I have 2 devices:

• one is advertising (server app running on android 11)
• one is discovering (client app running on android 4.4.2).

Both have the latest version of the Google Play Services.

On connection, the client app is sending some bytes to the server app; depending on those, it will send back bytes or a file. It works on all client devices I have except the Galaxy Tab 3 and I have no idea why. Sending bytes works, but not sending files (file is approx. 25Mo! i've tried 5Kb, same result : Payload Failure). On failing, client disconnects from server and then reconnects to it, only to fail again. After some tries, a pop-up often appears saying Play Services have stopped.

Does anyone have an idea why this is happening on this specific device?

I have some logs from my server app :

And the exception line from the bug report dialog on my client app (dialog doesn't show up every time so I don't know if this is the reason behind the Nearby's failure) :

java.lang.IllegalArgumentException: Requested flags 0x43, but only 0x3 are allowed

This is a bug in Nearby Connection's code! It's an instance of https://stackoverflow.com/questions/34740746/illegalargumentexception-in-granturipermission-on-api-level-19

I've just submitted a fix, but it'll take roughly a month until it's rolled out to devices.
