1 year ago Hi @codicusmaximus, I am facing the very same issue. Did you manage to resolve it? I am trying to reconnect to the controller via bluetoothctl as a workaround, but it fails since the device shuts down after disconnect.
I have had this issue ever since I first set up ds4drv over a year ago. It has been the same behavior with different Raspberry Pis as well.
The controller connects and works perfectly, but after anywhere between 10 minutes and 4 hours the controller stops sending button updates yet remains connected (LED stays on the same, bluetooth device shows on the list as connected, etc.). I need to hold the PS button for 10+ seconds to force the controller off and then turn it back on again to resolve the issue.
I finally got tired of this behavior and I'm trying to get to the bottom of it, so I did a bluetooth packet capture
In the screenshot, look at the Time column (second column). You can see the updates flowing (88 byte length packets) and then a 23 second gap. This is the controller updates stopping to flow, and then me turning the controller off and then back on again. There are no other suspicious bluetooth packets that I can see that would cause the controller to stop sending packets. Does the PS4 controller need an occasional poke every few minutes/seconds to keep sending the updates or does it just transmit forever? Why would it just all of a sudden stop sending the updates?
