periodic_adv_conn data ack

[joey]

hi

I am using periodic_adv_conn and periodic_sync_conn from the NCS 3.0.0 SDK.

After periodic_sync_conn reports data to periodic_adv_conn in the corresponding time slot, the periodic_adv_conn program normally calls the response_cb to parse the data. I see that the function calls bt_conn_le_create_synced to enable the periodic_adv_conn node and the periodic_sync_conn node to connect in the next cycle.

I now want the periodic_adv_conn to reply to the periodic_sync_conn when parsing the data in the response_cb, to acknowledge that the data has been received. So, is there any way to implement this reply directly, or must I use bt_conn_le_create_synced to establish a connection first before replying?

Thanks!

Hi, 

You have to use bt_conn_le_create_synced() to establish a connection before the advertiser can send a reply or acknowledgment to the scanner.
