Behringer Flow 8 bluetooth pin code?

[LeesKeys]

I'm trying to make Bluetooth connection between my Flow 8 and Google Pixel 6 phone. I've installed the app on my phone and turned on bluetooth. The phone senses the Flow but requires a pin code before connecting. I've seen this referenced on some other forums, but not solution. Has anyone else encountered this? By the way, the Flow connects fine with the app as set up on my iPad- no pin code required.
