Can ubt0 be a slave or a passive listener, and not a master?

This device has absolutely no buttons. Also camera has no such switch 
"GPS on". When cable is plugged in, it is supposed to be on. Very simple.

This is maybe what it is doing. Maybe it performs discovery itself, 
looks at some flags, and keeps silent because it didn't find the right 
flags ... But it isn't clear how to know which flags are those.

Yes, this device is AK-4NIII by the company called Aokatec. Camera is 
Nikon D300.
Their official description lists a bunch of GPS devices as compatible. I 
don't have any of this list.

When I confronted the manufacturer about the Android connectivity, they 
said they officially don't support Android "because Android is always a 
bluetooth master", and they are also a master looking for a slave. Their 
statement isn't correct, because there are few android apps that work as 
GPS slave and this is entirely possible. They also said that their 
master looks for slave with passcodee="0000"

I also confronted Android App maker "Bluetooth GPS". They said they know 
about Aokatec device incompatibility, but they have no clue as of the 
reasons.
