I was finally able to get it to work.
I thinking pressing setup, releasing then pressing mode worked. Maybe the lights are too close for my eyes to distinguish color.
The “correct” way to solve this issue is to use a udev rules file so that you will have permission to access the device.
Edit: You must also be in listening mode (blinking blue) as well.
