I have a new PC with an
ASUS TUF X570-Pro (Wi-Fi) motherboard, which has Bluetooth. I have the Wi-Fi/Bluetooth antenna connected and sitting on my desk about two feet from me.
For the last couple of weeks I have been playing games with a DualShock 4 v2, flawlessly. But starting last night, whenever I connect the controller, it disconnects within two or three seconds, and reverts to "Paired" instead of "Connected" in Bluetooth settings. Pressing the PS button reconnects the controller, but only for those two or three seconds.
If I'm in Steam Big Picture Mode, I can sometimes move the cursor one or two items before the controller disconnects, so it is working during those seconds.
The only other thing I can note is that right before it disconnects, the light on the controller flashes bright blue, then goes out. I don't know if that bright blue is the color I've assigned it through Steam, because it won't stay connected long enough for me to check.
Deleting and re-pairing the device, rebooting between pairings, doesn't help; I've done it several times. I didn't change anything else last night when this started. What could be causing this?
