Is there any example about the dongle nrf52840 act as a central? Is that possible? In that case for a ble connection between dongle and board a service does to be create on the peripheral or in the central part? Or both?..

Thanks a lot for answers!!

Hi

There should be no problem using the nRF52840 dongle as a central. This tutorial might help you setting it up. As for the second part of your question I am not sure I understand. Both the dongle and a development kit are able to act as both central and peripheral, if that is what you are wondering.

ok,thanks..but if i want to create my own service  have I to define it in the script of the central and in that of pheripheral or only one of this?.

Before i create a service on the dk as periphereal and i use it with nrfconnect and it's was ok.

If now i would program the dongle instead what should i do? program the dongle as a central and define again the service on it or it's enaph if the service is define only in the periphereal part?

Hi

I am struggling to understand what you mean by "service". Do you mean the application you are making?
