Hi,Team,
I am developing Long Range and Pawr using nrf54l15-dk.
For the Long Range example I refer to E:\NCS\v2.8.0\nrf\samples\bluetooth\central_and_peripheral_hr and peripheral_hr_coded.
For the Pawr example I refer to E:\NCS\v2.8.0\zephyr\samples\bluetooth\periodic_adv_rsp and periodic_sync_rsp.
I wrote the relevant configuration of the Long Range example into the Pawr example, used vscode to compile the Pawr example and downloaded it to nrf54l15-dk, and found that the communication could not be normal.
Here is the log I captured:
