If my goal was to goal is to utilize more bandwidth for advertisements but the advertising message is only initiated in 37/38/39, then extended advertisements don't do it for me. Especially since the standard advertising data packet is plenty for my application. Thanks for your confirmation.

Hi Sean,

You are partly correct.

The ADV_EXT_IND type packets needs to be transmitted only in the primary channels (37,38 and 39) but AUX_ADV_IND (Auxillary type) can be transmitted in the secondary. If your aim is to reduce the congestion, then you should transmit a minimal possible in the primary channels and try to stay more on the secondary channels.

In short, you are right the the start of the advertising event starts on primary channels, but that does not mean that you need to stay on them all the time.
