Load Cronus PRO and go to Tools > Options > Device
Set the Output Protocol to PS4.
These are also the recommended default Speed Up Settings for DualShock 4 Wireless Controllers.
Check the box to the Left of 'Enable DualShock 4/Wiimote Bluetooth searching'.
The recommended Speed Up Settings when using a DualShock 4 Controller with a Bluetooth 4.0 USB Adapter are as above - you can choose to tweak with them if you have any issues. If you have a slower Bluetooth adapter or experience any issues with rumble then you should try different 'Rumble Over Bluetooth' speed settings. You have the alternative options of Flow Control+, Flow Control and Disabled.
Select the CMax Plus Tab and make sure the box to the left of 'Enable PS4 partial crossover support (auto reconnect every 10 min)' is NOT checked.
We also recommend you select the 'Mimic Controller Player LEDs' option if you have CronusMAX PLUS v3 device. This is especially useful if you plan on using our GamePacks.
You can now close the Options window and disconnect your CronusMAX PLUS from your PC.
Press and hold the SHARE and PS buttons on your DualShock 4 until the light bar starts to flash white. Once it starts flashing white, the controller is searching and connecting to the CronusMAX PLUS.
After a few seconds, the light bar should change to a solid color (usually blue if Player 1) and is now paired with the CronusMAX PLUS.
The dot in the top left hand corner of the LED display will continue to flash while the CronusMAX PLUS is in use. This is perfectly normal as the CronusMAX PLUS is notifying you whenever it receives a security request from the console.
If the LED on the CronusMAX PLUS does not change from AU to a number then the authorization controller is not authenticating. 99% of the time we find that this means the Micro-USB cable to the controller is faulty or not full data or simply not compatible, you should try another one. Another issue that sometimes comes up is that the controller USB port has a loose data pin. It will charge fine, but won't transmit data. Also make sure the controller is powered on of course - that's a rookie mistake.
Bluetooth and Wi-Fi devices use the same radio frequencies to communicate, they often interfere with one another and are prone to interference from other devices operating on the same frequencies. If you are experiencing lag with your wireless controller, even though you have tried different Speed Up Settings in the Device Options panel, there is a good chance you have a WiFi Router that is causing interference. We have found that routers such as Apple's Airport Express have this problem and you should make sure that the router is not in close proximity to your CronusMAX/Bluetooth Adapter. You should also try changing the WiFi Router Channel to optimize your wireless signal. Click Here for more information on how to do that.
We also recommend that you Click Here to check out an article that looks at the effects of such interference, what causes it and how to reduce it in a home or office environment.
If you do not intend to use your DualShock 4 controller without the CronusMAX PLUS in the future, you can now disable DualShock 4 Bluetooth searching to speed up subsequent DualShock 4 wireless syncing.
This would also mean that next time, you can skip steps 1 through 3 and instead of holding the SHARE and PS buttons in step 6, you would simply press the PS button
