HM10 ble module

Hello guys, I am using hm 10 ble module for scanning ibeacons. I connected the module to terminal using serial module and it is responding to commands such as
AT
AT+ROLE
AT+VERSION etc.

However, when I give it the command for scan discovery of ibeacons which is
AT+DISC

Then it is not responding. Also, there is a command for getting mac address which is AT_ADDR. When I run this command, it returns 00:00:00:00:00:00.

Kindly give suggestions how to solve this issue, and scan ble beacons.
