HM-10 discovery issue
The HM-10 is a BLE-only device. 

Android phones do not normally transmit BLE advertisements, so there is normally nothing about an Android phone for it to discover.

The exception would be if you have software on a late Android version with the capability, which you have set up to intentionally transmit BLE advertisements, or else if software you put on your Android phone is actively responding to advertisements you had the HM-10 transmit.

Essentially, you are expecting something that his not normal behavior, but will only be achieved by adding your software on both devices.
