Android phone wants code for bluetooth, device cannot show code...?

[Android Central Question]

I'm trying to connect my android bluetooth to a vaping mod ... the ocular c. That mod cannot show any code for verification.
I have tried; 0000, 1111, 1234 and the like, and am still met with "unable to verify".

When I do a BT scan for devices, the mod lights up, it's communicating, but there's no way to bypass the code I can find. Help & ty.

It pairs fine through the app ... twisted420 on youtube showed how to do it
