Hi, I heard back from the development team. on this issue. You should only use the parameter values supported for a parameter and not the BT GAP Advertising Type. The advertising options should be better suited here. If no options are set (set to 0 or BT_LE_ADV_OPT_NONE) the advertising is non-connectable. You should set BT_LE_ADV_OPT_CONNECTABLE to make an advertisement connectable.

All advertising options can be found here. BT_GAP_ADV_TYPE_ADV_NONCONN_IND is not the value to be used for options parameters in the API, and you shouldn't use any value for the bt_le_adv_start API's option field of the "bt_le_adv_param" parameter.

Best regards,

Simon

Thank you for all the information! I have now reported this internally, and we'll try to fix this for the next release of the nRF Connect SDK.

Best regards,

Sorry, I forgot to ask this, but what SDK version are you using here? Do you see it in the latest version v1.9.1 of the nRFConnect SDK as well?

Best regards.

I was using nrf Connect app

To reproduce use the code above or manually set the param.options to BT_GAP_ADV_TYPE_ADV_NONCONN_IND
This is an enumeration and resolves to 3 but the code in adv.c: bt_le_adv_start_legacy() function treats params.options as a bitfield (line 970 and down)

What Bluetooth scanner tool are you using exactly, and how can we reproduce this with a DK for example? This might be a bug on our side, but I'd like to reproduce it before reporting internally.

Best regards,

Simon

BT_GAP_ADV_TYPE_ADV_NONCONN_IND is a wrong value to use here.

params.options field should be set to zero for the packet type to be non connectable undirected (3)
