Subject: [PATCH 2/2] Bluetooth: Set HCI_QUIRK_WAIT_FOR_MATCHING_CC for QCA9377
Date: Tue, 23 Apr 2019 15:22:36 +0800 [thread overview]
Message-ID: <20190423072236.24999-3-jprvita@endlessm.com> (raw)
In-Reply-To: <20190423072236.24999-1-jprvita@endlessm.com>
The QCA9377 devices send an extra command complete for the
LE_SET_RANDOM_ADDR when trying to start an active scanning procedure. It
has to be ignored to avoid confusing the kernel into thinking a passive
scanning procedure is being performed instead, which makes impossible to
discover BTLE devices since no device found events are generated for
passive scanning.
