How to connect nRF 52 development kit with nordic thingy:52 wirelessly without any cable?

Question

Since nordic thingy:52 can work wirelessly, can we connect it with nRF DK wirelessly and if so, how can we do it?

This is a very good question. As you most likely know, the Thingy:52 was created to make quick IoT prototypes & demos, so the main use case is to use the Thingy:52 with the provided smartphone app available for Android & iOS (search Nordic Thingy). 
 For starters, I would take a look at the Thingy FW located here to get a good understanding of how the Thingy SDK is built up. At the bottom of the link, there is a section on compiling the code, which works for both the Keil IDE & the gcc compiler. 
 Then, I would take a look at the multilink demo provided here , where a 52 DK can be used as an aggregator device between other dev kits & the Thingy:52 device. That should give you a good starting point for developing your own code. I do not believe you will need to modify the Thingy SDK to get this working.
