Hi,

[quote user=""]I have bought NRF52840 dongle to bring up my prototype as fast as possible. I am new to Bluetooth tech.[/quote]

I would suggest you use nRF52840DK for the development because the nRF52840 dongle doesn't have the on-board debugger. Please also see this tutorial nrf52840-dongle-programming-tutorial for the usage.
