I have one JDM 40 - DS4 controller, Charging  - normal, connecting with USB  - normal, when i connect it with USB cable to Console, controller conecting as usual, removing usb cable - controller working normal with bluetooth.

But when i restart or close console. Controller forgetting and not remembering PS4 console.

I need again to connect with USB cable , then everything working again. I also 3-4 times do a hard reset this controller, removed every registered DS4 in console , change cables, etc etc. Controller also connecting to gamepad tester site. No stick buttons.

I am not newbie at electronics, soldering , etc. But i need litle help with that problem,  point me direction pls,  where to dig ? MCU ?

firt of all disconnect it from mobile phone. second one - choose bluetooth connection, not usb is settings-conroller. third one - you should shutdown ps4 from menu and then power it on from ds4.

I tried everything you recomended here, also conected it to console with bluetooth search ( Share+PS ) button, conecting perfectly.

I shutdown through menu, restarting trough menu, connection gone, controller forgetting console. And i have 2 controllers which working as intended on same console.

Problem is in controller motherboard somewhere. But where ?
