previously discussed in the posthttp://support.dialog-semiconductor.com/removing-ad-flags-advertising-pa...that it's illegal to send no flag AD.
But the fact is that BLUETOOTH SPECIFICATION permit no flag AD,“ The Flags AD type shall be included in the advertising data if any of the bits are non-zero. The Flags AD type may be omitted from the advertising data if all of the bits are zero.”
so please reconsider the unneccesary limit.Currently is it possible to send no flag AD?

Hi toughworld,
As far as we know this is not allowed by the current stack, at least so far we cant set the AD Flags to zero in order for the initial 3 bits to be ommited. Even if you manage to advertise without LE Limited Discoverable Mode and LE General Discoverable mode the da doesn't support BR/EDR so this flag will always be set.
Thanks MT_dialog
I got it.You are correct while CSR's stack allow no flag AD.
I'm just trying mesh adopting CSR mesh protocal.
