Extended advertising call-back register

[axel_s]

Hallo,

currently I try to optimise the functionality of my extended advertiser code. I found that there are also some call-backs defined for extended advertisers. The struct bt_le_ext_adv_cb contains fields for sent, connected and scanned call-back functions. But I didn't find a function to register my call-backs. In case of scanning devices, there is the struct bt_le_scan_cb, an instance of which is to be used with the register function bt_le_scan_cb_register(). How can I realise that in case of extended advertising call-backs - does an appropriate "bt_le_ext_adv_cb_register()" function exist?

Kind regards

Axel

Hello,

If you have a look at the sample found in:

NCS\nrf\samples\bluetooth\multiple_adv_sets, you can see that this uses an instance of bt_le_ext_adv_cb, which is registered using bt_le_ext_adv_create() inside advertising_set_create();

This is all implemented in adv.c, and relying on already existing events in hci_core, such as bt_hci_le_adv_set_terminated() and bt_hci_le_scan_req_received(). The implementation inside adv.c is not too difficult to read. It just checks whether the callback exists (not NULL), and then it triggers the appropriate callback.

Best regards,
