CC2640: The notification for the end of advertising on CC2640

Hi Nomo,

I don't understand your question. What is the name of the event you're referencing?

Hello Marie-san,

I apologize to make you confused.
They are checking the notification of HCI_EXT_AdvEventNoticeCmd and the notification of iCall for advertising.
Despite the notification of HCI_EXT_AdvEventNoticeCmd, they can see the notification of iCall (Success).

So, they want to know the specification of the notification of iCall.
They think that it seems the notification of iCall for advertising only depends on the timer event.

Best Regards,

Hi Nomo,

I still don't understand anything. You can use HCI_EXT_AdvEventNoticeCmd() if you want to receive a SBP_ADV_CB_EVT every time an advertisement ends, but your device can advertise without receiving/subscribing to this event.

If you want to make sure the device is advertising, you can use a sniffer or a smart phone with a BLE app.

What are they trying to achieve?

Hello Marie-san,

Thank you for your reply.
They are trying to achieve combining simple_broadcaster and simple_observer.
And they want to achieve advertising and scanning simultaneously.

But sometimes advertising doesn't work correctly.

Have you heard the failure for the system which is advertising and scanning simultaneously?

Hi Nomo,

I would guess if the BLE-Stack wants to send an advertising packet at the same time as scanning (rx), it would cause an issue. What are the scanning and advertising parameters? (Scan duration, scan interval, scan window, advertising interval)

Hello Marie-san,

Thank you for your reply.
The parameters are following.

Scan duration:
They don't call GAP_DeviceDiscoveryCancel, it seems the scanning is working continuously.

Scan interval: 512ms
GAP_SetParamValue(TGAP_GEN_DISC_SCAN_INT, 512 / 0.625);

Scan window: 20ms
GAP_SetParamValue(TGAP_GEN_DISC_SCAN_WIND, 20 / 0.625);

Advertising interval: 100ms
GAP_SetParamValue(TGAP_GEN_DISC_ADV_INT_MIN, 100/0.625);
GAP_SetParamValue(TGAP_GEN_DISC_ADV_INT_MAX, 100/0.625);


Best Regards,

Hello Marie-san,

Thank you for your reply.
I can understand it needs to adjust the settings such as scan window.
