I have the following setup:
- 3 switch pro controllers paired with blueman bluetooth
- Raspberry Pi 4 Model B Rev 1.2
- Raspbian GNU/Linux 10 (buster)
- latest steam link to my windows 10 pc
as long as I have only 2 controllers connected, everything is working very smoothly, we can play games well. no lag no nothing.
But as soon as I try to connect the third controller (no matter the order), none of the other controllers work properly anymore, after a minute one of the controllers gets lost and does not work in game anymore.
Any idea on how to fix this and help me connect the third and 4th controller?
sudo btmon
to see if that gives you more debug information. Other experiments you could try is disabling the wifi. Using a separate Bluetooth USB dongle to connect the controllers to.
