Bluetooth: Periodic Advertising with Responses (PAwR) Synchronization


A simple application demonstrating the BLE Periodic Advertising with Responses Synchronization functionality.

This sample will echo the data received in subevent indications back to the advertiser.

Which subevent to listen to and in which response slot to respond is application specific. In this sample it is decided by the PAwR advertiser. Upon connection it will write to a GATT characteristic the assigned subevent and response slot.

Flash this sample to multiple devices and they will be given different subevents and response slots, to that they can communicate with the advertiser concurrently.


  • A board with BLE support

  • A controller that supports the Periodic Advertising with Responses (PAwR) - Scanner feature

Building and Running

This sample can be found under samples/bluetooth/periodic_sync_rsp in the Zephyr tree.

Use the sample found under samples/bluetooth/periodic_adv_rsp on another board that will start periodic advertising, which will connect to this sample and transfer the synchronization info.

See bluetooth samples section for details.
