Advertisement interval always with delay

[swap007]

Hi Folks,

As per bluetooth spececification(4.4.2.2.1) advertising interval has addition of advDelay in range of 0-10ms. In my example,

1. device advertise beacon (sd_ble_gap_adv_start())

2. stops advertising function call(15ms) before next  advertising interval. sd_ble_gap_adv_stop()

3. app timer expires ~100ms

4. Do step 1

Q) Effectively, i am not using advertising interval mechanism, Is softdevice add random delay ?

Thank you.

 Yes, The link layer in the softdevice adds the random delay of 0-10ms to your requested advertising interval. The application has no control on this random delay.
