Scanning Mac addresses using bluetooth modules

Hello
I am new on bluetooth stuff. I started the studying because i want to make a project which will scan for a bluetooth Mac address (my phone’s MAC address). I would like to know if something like that is possible. I tried to build that project using 3 different bluetooth devices but for some reason on the first and the second bluetooth i couldn’t use the INQ command and on the 3rd bluetooth i could not find the MAC address of my phone in the search list. The 1st time i tried that was with a AT-09 which is a clone of HM-10, the 2nd bluetooth device i used was hc-05 and the last one i used was a jdy-24.
Thank you for your time
