Return-Path: Message-ID: <4E45B5F1.4020807@Dartmouth.edu> Date: Fri, 12 Aug 2011 19:23:29 -0400 From: Isaiah Sarju MIME-Version: 1.0 To: linux-bluetooth@vger.kernel.org Subject: RFCOMM channel 1 behavior differences Content-Type: text/plain; charset=ISO-8859-1; format=flowed Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Hello, Does Ubuntu, linux kernel 2.6.38.10, running bluez 4.91-0ubuntu1 have a special security policy for incoming rfcomm connections on channel 1, and not other channels? I ask this because I can create rfcomm connections between two computers on other channels (2, 3, 11, 13, etc.) but the listening computer refuses connections when connection requests come in for channel 1. I use the following commands: on listening computer: sudo rfcomm listen hci0 on connecting computer: sudo rfcomm connect hci0 When does not equal 1 both computers connect no with no problem. When equals 1 I receive the error "Can't connect RFCOMM socket: Connection refused" I tried this in to two different environments. 1) in a X-session and 2) in command line 1) in GUI on the listing computer a dialogue box pops up requesting a pin for pairing. When I click cancel on the dialogue box of the listening machine the error "Can't connect RFCOMM socket: Connection refused" appears on the command line of the connecting machine. 2) in command line mode on the listening computer nothing appears and I immediately receive the error "Can't connect RFCOMM socket: Connection refused" on in the command line of the connecting machine These problems do not arise when attempting to connect on any other channels. I have searched Google, looked at multiple forum posts on rfcomm connections, looked at forum posts on peoples' problems with rfcomm connections, reviewed this mailing list's archives, and I cannot find my specific problem. Thank you for any advice you can provide or resources to which you can point me. Regards, Isaiah
