Good evening, after a few days of trying I managed to get my SET to work: BELOADER + CRONUSZEN + XIM APEX.
Connections:

My hardware:
- PS5 DIGITAL
- BELOADER WITH LATEST FIRMWARE (WIFI)
- CRONUSZEN WITH LATEST FIRMWARE AVAILABLE (OUTPUT PROTOCOL ON AUTO / PS4 SPECIALTY OFF)
- XIM APEX WITH LATEST FIRMWARE AVAILABLE (1000HZ POLLING RATE)
- POWER SUPPLY (FOR HUB XIM APEX) 5V 2A
- POWER SUPPLY (FOR BELOADER) 5V 3A
- DUALSHOCK V1 FOR XIM APEX
- KEYBOARD FNATIC STREAK65
- LOGITECH G502 HERO MOUSE (SET TO 25k DPI - 1000HZ POLLING RATE)
- USB CABLES SUPPLIED WITH CRONUSZEN
I state that if I connect Beloader + Xim Apex I do not find any anomalies, I can play without disconnections, I only have a little delay due to the use of WiFi, a problem that I think I will solve by connecting beloader to a LAN ETH> USB adapter, WASD works.
If instead I connect the BELOADER + CRONUSZEN + XIM APEX I find (watch the video below) synchronization problems (I think) in the WASD keys, if I press the W key for example the first time it will work quietly, once I press W again, Xim records the pressure but does not carry out the command, same for the ASD keys.
Is it possible to do anything to avoid this? Is this a solvable problem? Will any updates come out?
