Control another phone via bluetooth I need to control an android phone by another android phone using bluetooth.

Same as Teamviewer, but via bluetooth.

Suggestions ?

I have root and xposed.

So far I found only apps that use Wifi, or that transmit to a TV. Not what I need.

To make it more difficult: one of the devices is android 4.1

Edit 1: I said mirror before. It was wrong. I meant control. Need to view and control another device.

Edit 2: It may be something different than bluetooth, as long as no internet be required.
RemoDroid is the answer.
Works through WiFi Direct.
Works on older phones by using older versions  (0.15.4 worked on my 4.4.0, same version installed on both).
Not bluetooth, but works.
Thanks Robert for showing the way
