References: <20040813002514.GA21388@bougret.hpl.hp.com> In-Reply-To: <20040813002514.GA21388@bougret.hpl.hp.com> Content-Type: text/plain; charset=us-ascii; format=flowed List-ID: Hi, Jean, Can you reveal what you're doing with the CSR device when you suffer deadlock? We may recognise the symptoms, and possibly know of a workaround or of fixed firmware. Build 0x1bb is "HCI 15.3", released in August 2002. Build 0x20e is "HCI 16.4", released in October 2002. HCI 16.4 introduced basic scatternet support and fixed some issues in HCI 15.3. HCI 16.14 (build 0x33d) was published to product manufacturers in April 2003. This fixed a handful of issues in HCI 16.4. You may be able to get hold of this, but I have no knowledge of what firmware D-Link have tested with their hardware and have subsequently (signed and?) published. If your hardware is suitable (i.e., if it has an 8 Mbit flash device), you may be able to load HCI 18.1 or HCI 18.2; these support BT 1.2.
