I want make connection secure between mobile app and thingy52. What are the types for secure connection. Currently anyone can connect thingy without any permission.

Hi Nilesh, 

The Thingy52 firmware doesn't have that supported. You would need to download the Thingy SDK and then implement that on your own. We have the peer manager library that can handle that task. You can refer to our example in nRF5 SDK v11 for example the ble_app_proximity.
