Return-Path: From: Daniel Benoy To: "Support for Openmoko Device Owners" Subject: Intermittant bluetooth keyboard Date: Mon, 8 Sep 2008 13:23:15 -0400 Cc: linux-bluetooth@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Message-Id: <200809081323.15887.daniel@benoy.name> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: I set up my bluetooth keyboard on my openmoko phone using the 'new' (In other words, not hidd, but still dbus) input interface, and it only works like 10% of the time. That means when I turn it on it should connect and start working. Unfortunately, it only works about 25% of the time, and I have to switch it off and on frequenly in order to get it to finally connect. I get this output from hcidump -V when it doesn't work: > HCI Event: Connect Request (0x04) plen 10 bdaddr 00:0A:DF:00:24:59 class 0x002540 type ACL < HCI Command: Accept Connection Request (0x01|0x0009) plen 7 bdaddr 00:0A:DF:00:24:59 role 0x00 Role: Master > HCI Event: Command Status (0x0f) plen 4 Accept Connection Request (0x01|0x0009) status 0x00 ncmd 1 > HCI Event: Connect Complete (0x03) plen 11 status 0x22 handle 42 bdaddr 00:0A:DF:00:24:59 type ACL encrypt 0x00 Error: LMP Response Timeout The difference in time between 'Accept Connection Request' and 'LMP Response Timeout' is about 3 seconds. I was under the impression that LMP negociation was supposed to time out after 30 seconds? Is there something I'm doing wrong? Am I not interprating this correctly? If it does work I get something like this: > HCI Event: Connect Request (0x04) plen 10 bdaddr 00:0A:DF:00:24:59 class 0x002540 type ACL < HCI Command: Accept Connection Request (0x01|0x0009) plen 7 bdaddr 00:0A:DF:00:24:59 role 0x00 Role: Master > HCI Event: Command Status (0x0f) plen 4 Accept Connection Request (0x01|0x0009) status 0x00 ncmd 1 > HCI Event: Link Key Request (0x17) plen 6 bdaddr 00:0A:DF:00:24:59 . . . (And then link key request reply and so on it does its negociation and there you have it) -- Daniel Benoy http://daniel.benoy.name
