The one-to-many test for periodic_sync_conn and periodic_adv_conn failed.

[Noah Qing]

Hi ,I flash periodic_sync_conn sample to  A and B development boards, and periodic_adv_conn sample to C development board. Only A and C development boards work normally, but B works abnormally. Do I need to make any changes to B? thanks.

Hi,

Can you provide links to the samples which you tested on your boards?

Which NCS version did you use?

Are all 3 boards used in your testing nrf52840-dk boards?

Best regards,
Dejan

Hi,

The problem of not connecting is not exclusively related to the board B, but it could also appear on the board A. It is not unexpected to see only "Responding with own addr: <address> (random)" when you use more than 2 boards. Advertising side is trying to sync and connect. It avoids new connections if it has already been connected. This can be seen in the response_cb().

Best regards,
Dejan
