Hi @Kristin, I have the similar kind of confusion.

Advertisement packet send on three channels in one advertisement event (Advertisement interval) or packet send sequentially at every advertisement event, packet over one channel at advertisement event. For more clarification on my question, take an example of 1 Sec advertisement interval, so advertisement packet send on three channels in 1 Sec or packet send sequentially on three channel at every 1 Sec, so total 3 Sec. require to send packet on three channels.

Hey Kristin,

Thank you for your answer but I'm trying to looking into the time for which the advertising event goes on ie tWA and not the advertising interval. Please refer to the figure I posted.

Thanks, Vandita

The advertising interval is set in the code, and should be in the interval 20 ms to 10.24 s (Bluetooth Core Specification v 4.2, Vol 2, Part E, chapter 7.8.5).

In the examples, the advertising interval is set with APP_ADV_INTERVAL.

If you want change the advertising interval constantly, you can use a timer to update the advertising parameters. However, I cannot see any good reason to do that.

Update 30.03.16: The softdevice specification (SDS) for the softdevice you use has the diagram that (I think) you are looking for.

The S130 SDS, chapter BLE power profiles --> Advertising event shows the current consumption for an advertising event.
