Hi this may sound as a stupid question.But I was unable to find any answers for this, thus posting here.

Your code snippet should work - Only that it will be expensive in terms of power draw and will certainly kill your device/phone in a few hours. The startDiscovery() does a 2 step process, finding the device by inquiring for it and followed by a name discovery ie paging and connecting to the device,

Unfortunately Android does not provide any API to control this and do only inquiry , also there is a periodic inquiry feature defined and supported by most Bluetooth chipsets, Android currently does not have any API to do periodic inquiry which could have been more ideal for your use case.
