Your link alludes to BLE devices, which the HC-05 isn't.

If your phone IOS, your only option is to ditch the HC-05, and obtain a BLE device for use with sandeep - whatever that is.

If you have the HC-05 in your hand, and your phone is Android, you have two options

  1. obtain a BLE device for use with sandeep.
  2. forget Sandeep, and use the HC-05 like everybody else does.

I recommend the latter. The rest of your post is just technobabble, and
