Subject: [PATCH BlueZ 0/3] emulator: Fix extended advertising report types
Date: Mon,  5 Oct 2026 09:21:14 -0700	[thread overview]
Message-ID: <20261005162117.4606-1-kevin@simpleble.org> (raw)

btdev sends the wrong Event_Type in two of the LE Extended Advertising
Reports it generates for an advertising set:

- the scan response to non-legacy scannable advertising is reported
  with Event_Type 0x0000 instead of 0x000a
- with more than one active scanner, every scanner after the first gets
  the advertisement reported as a scan response

The first patch removes le_ext_adv_type, which sits next to this code
and has been unused since advertising sets got their own struct.

I reproduced both with a small test driving an advertiser and two
scanners in-process. On master it shows:

  scannable set: scan response 0x0000, expected 0x000a
  two scanners:  scanner 1 adv 0x001b, expected 0x0013

I can send it as a unit test if that would be useful.

mgmt-tester, iso-tester and smp-tester give the same results with and
without the series, apart from LL Privacy tests that fail
intermittently on both.
