I am just a Android user, but I believe my observations and questions are interesting and relevant to people in this forum.

I use a Samsung Galaxy A3 (2017) and wanted to use one of the many VLC remote control apps towards my Ubuntu computer that has a Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (Lite-on). Unfortunately none of them worked. All had network issues. I tried different ports and also used several browsers to access the http server of vlc directly, but even the browser had issues: it basically kept synchronised for 4 or 5 seconds, then lost synch and recovered only after roughly 15 seconds just to loose synch again after 4 or 5 seconds.

I checked the TCP connection. It did not break down. However, every 4th or 5th GET request got delayed by around 14 seconds.

I digged into it and found out that the A3 sends a TDLS Setup Request to the QCA9565, gets a TDSL Setup Response and then sends a TDLS Setup Confirm which is replied by the QCA9565 with a TDLS Teardown. After that, the connection between the two hosts is dead for about 14 seconds.

Other hosts in the network did not have such issues, but as far as I can see, they are also not using TDSL. So I suspect that some issues with TDLS between my Samsung A3 and my Ubuntu machine regularly interrupt the local WiFi connection between the two.

So now my question: Is it somehow possible to disable TDLS on my Android phone? Or are there any vlc remote apps around that somehow suppress TDLS for such local WiFi communcation?
