Can nrf52840 Dongle be detected as a bluetooth Device but not a serial port?

[Geass77]

Like the question, I want the dongle to be detected as a bluetooth device but not a serial port. Is there any method to do this? 

And I want to ask if  it be possible to build connecting between nrf52840 DK and nrf52840 Dongle?

Hi. 

The nRF52840 is, as the name suggests, based on the nRF52840 SoC. 

You are free to program the nRF52840 Dongle with a BLE application so that you can connect it to other devices using BLE. There are examples supporting the dongle (PCA10059) in the nRF5 SDK. 

Please take a look at the blog-post below for more information about the nRF52840 Dongle.
