    It’s been two weeks, but ASUS working now and connected to a 4-Port USB hub with power adapter (Sabrent brand). The benefit is that I can turn the ASUS bluetooth off and back on from the hub in order to reset the bluetooth and get the keyboard connected again.

    The key is to setup the MacBook Pro 15 with that command line that tells the computer to look for external bluetooth sources first before going to the internal Bluetooth. It bypasses that crummy bluetooth module inside the laptop.​
