* [PATCH] Service Discovery Collison with Lenovo T500 Laptop. [not found] <SDP_COLLISION> @ 2012-02-14 9:19 ` rajmohan.mohanan 0 siblings, 0 replies; 3+ messages in thread From: rajmohan.mohanan @ 2012-02-14 9:19 UTC (permalink / raw) To: linux-bluetooth; +Cc: mohanan From: mohanan <rajmohan.mohanan@intel.com> ISSUE: 1. Intiate bonding from DUT. 2. After Successfull Bonding complete, DUT and Remote device intaites Service disocvery. 3. Service Discovery from either end results a collision and L2cap Connection for SDP from DUT is rejected. 4. From DUT if we send a file ,from android application service Records are NULL becuase service discovery from DUT didnt succeed due to collision. 5. Android application will return status as failure and he wont intaite a fresh sdp query so OPP transfer Fails. FIX: After bonding complete wait for one second and Intaite Service discovery for avoiding service discovery collision if remote device intiate service discovery immediately after bonding.

* [PATCH] Service Discovery Collison with Lenovo T500 Laptop. [not found] <Sdp collision> @ 2012-02-14 8:57 ` rajmohan.mohanan 2012-02-15 9:39 ` Mohanan, Rajmohan 0 siblings, 1 reply; 3+ messages in thread From: rajmohan.mohanan @ 2012-02-14 8:57 UTC (permalink / raw) To: linux-bluetooth; +Cc: mohanan From: mohanan <rajmohan.mohanan@intel.com> ISSUE: 1. Intiate bonding from DUT. 2. After Successfull Bonding complete, DUT and Remote device intaites Service disocvery. 3. Service Discovery from either end results a collision and L2cap Connection for SDP from DUT is rejected. 4. From DUT if we send a file ,from android application service Records are NULL becuase service discovery from DUT didnt succeed due to collision. 5. Android application will return status as failure and he wont intaite a fresh sdp query so OPP transfer Fails. FIX: After bonding complete wait for one second and Intaite Service discovery for avoiding service discovery collision if remote device intiate service discovery immediately after bonding.

Regards Rajmohan -----Original Message----- From: Mohanan, Rajmohan Sent: Tuesday, February 14, 2012 2:28 PM To: linux-bluetooth@vger.kernel.org Cc: Mohanan, Rajmohan Subject: [PATCH] Service Discovery Collison with Lenovo T500 Laptop. From: mohanan <rajmohan.mohanan@intel.com> ISSUE: 1. Intiate bonding from DUT. 2. After Successfull Bonding complete, DUT and Remote device intaites Service disocvery. 3. Service Discovery from either end results a collision and L2cap Connection for SDP from DUT is rejected. 4. From DUT if we send a file ,from android application service Records are NULL becuase service discovery from DUT didnt succeed due to collision. 5. Android application will return status as failure and he wont intaite a fresh sdp query so OPP transfer Fails. FIX: After bonding complete wait for one second and Intaite Service discovery for avoiding service discovery collision if remote device intiate service discovery immediately after bonding.
