How to find the advertisement count in nrf51

[Pavan kumar]

Hii guys I am using an nrf51 DK board for my project and I am trying to find the number of advertisements send from the time the board was power up or reset. From my knowledge there is no ble event to find the advertisement was send(tell me if any). So can any one please help in that regards

Hi Pavan,

There is no such information being recorded in the stack, but it is possible to do it yourself if you need to.

If all you do is advertise, it is possible to use radio notifications to increment a counter. This feature will give you an interrupt before and/or after the radio is used by the stack.

For more information, see the SoftDevice Specification Chapter 8 (this is for S110, but the feature is similar in S120 and S130), the ble_radio_notification example in the SDK (tutorial here) and the sd_radio_notification_cfg_set documentation in the Info Center.

Hii Ulrich thanks for your reply

But I am Little bit confused with the Figure 5. on page number 16 that saying that multiple packets may also transfer in a single radio notification in that case how can we found the count of advertisement frames

[Ulrich Myhre]

Yes, the advertising procedure will advertise on 3 channels and wait for a scan request after each advertisement. However, you should only get one notification per full event. If you want to know each individual advertisement report on every channel, you will have to multiply the number you get with 3 (or the number of channels, if you are disabling some of the channels for any reason).

I just want to add that we have a tutorial about Radio Notifications, see this.

I know this is a bit old topic, but what if one does not only advertise, e.g. scan also. How can you measure how many advertising packets you have sent so far?
