Is ADS-B supported by Tower

I got ADS-B receiver installed on my quadcopter and it works OK in Mission Planner.

But when the ground module in transferred to the cell phne where Tower is installed, the ADS-B
not work… no commercial aircraft is displayed in the screen.

Is ADS-B supported by Tower ?

Appreciate any help.

Tower? What version would that be? I have Tower on an old Android phone in the junk drawer. Before ADS-B was even supported by Ardupiot perhaps?

My version is Tower v 4.0.0.

Is your Tower supporting ADS-B if you have one connected ?
