From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: =?UTF-8?q?I=C3=B1aki=20Arenaza?= To: linux-bluetooth@vger.kernel.org Cc: =?UTF-8?q?I=C3=B1aki=20Arenaza?= Subject: [PATCH 0/1] device: Some devices send HSP UUIDs in the wrong order Date: Mon, 13 Jul 2015 23:32:48 +0200 Message-Id: <1436823169-32164-1-git-send-email-iarenaza@mondragon.edu> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Sender: linux-bluetooth-owner@vger.kernel.org List-ID: [Please, CC me as I am not subscribed to the list.] Hi all, Some devices behave contrary to what Erratum #3507 [1] says for the v1.2 Headset Profile (HSP). They report HEADSET_HS_UUID as the first value of the ServiceClassIDList attribute, and HSP_HS_UUID as the second one. At leat one of those devices is the Energy Wireles BT 3 Ruby Red (from Energy Sistem). [1] See section 6.15 of https://www.bluetooth.org/docman/handlers/downloaddoc.ashx?doc_id=231555 To make sure the issue is due to the headset and not to the Bluetooth controller firmware, I have tested it with two differente computers having two different controllers. Below are the full details of the headset model, the two computer models, the Bluetooth controller models, the raw output from sdptool before applying the proposed patch (it's exactly the same in both computers, so I'm attaching the details just once), and the output from bluetoothctl when pairing the headset before and after applying the patch (again the same on both computers, so attaching it once). If I don't apply the patch, the headset is not recognized as an HSP device and is not usable from Pulseaudio (I can just use the A2DP mode of it). With the patch applied, it is correctly detected and can be used either in A2DP or HSP mode in Pulseaudio.
