Make Bluetooth Discovery indefinate

[xxrzdxx]

Is there a way to keep bluetooth discovery mode on all the time?

I am aware that this will effect the battery, and that pairing with a device should allow it to connect automatically. In my case, what I need to connect to does not.

I've been searching online but can not find a good answer, other than this is possible in newer android versions. So I don't have my hopes up.
