Can one deivice be both the central device and peripheral device?

Hi,

I am wondering whether I can have one "RELAY" device in BLE communication (not BLE mesh), I have look through this forum but only saw some example 5 years ago. As I am using the NCS 2.91, Is there any sample for this task? Could you please give me some information?

Thank you so much!

Hi

Yes, there is no problem for a device to act as both central and peripheral (and based on that act as for instance a relay). You can see an example of this in the Bluetooth: Central and Peripheral HRS sample.
