I have a couple of bluetooth devices that will not show when searched to pair with, but when I use a couple of different software that look for a bluetooth device to send say a picture of data it sees the device, but I can't pair with them.

One is a bluetooth GPS the second a bluetooth OBDII reader.

Phone is unlocked using Blackra1n, has BTStack.

Is there an app that replaces the iphone one to pair devices.
