Sender: bluez-devel-admin@lists.sourceforge.net Errors-To: bluez-devel-admin@lists.sourceforge.net Reply-To: bluez-devel@lists.sourceforge.net List-Unsubscribe: , List-Id: BlueZ development List-Post: List-Help: List-Subscribe: , List-Archive: Date: Fri, 21 Jan 2005 02:07:42 +0000 (GMT) Hi there, I have very simple requirements for a bluetooth 'beacon' that is discoverable, but nothing else (ie. it responds to discovery requests, but you don't need to connect to it or anything). At the moment I am using a D-Link USB dongle where the USB powerlines are soldered to an external power supply. This supplies power to the beacon, but it still needs to connect to a linux/bluez equipped laptop (with USB power disconnected as it draws its power externally) to bring up the device and make it discoverable. Immediately disconnecting the bluez laptop you then have a cheap standalone beacon as long as the power remains. I'm wondering is there any way to have a beacon like this where you don't have to connect it to a laptop after its been powered up to make it discoverable? My searches on google and looking at the bluez code make me think that normally a HCISETSCAN ioctl is sent to the device with SCAN_INQUIRY|SCAN_PAGE option to make it discoverable. My question is are there any dongles out there that become discoverable immediately when they are powered without having to send them a HCI command? One of you who have written drivers for these things might know.... Or if there aren't, can anyone suggest another way I might go about making or designing a cheap self powered bluetooth beacon that is discoverable on powerup? I may want to manufacture these beacons in some quantity later. Thanks, David ___________________________________________________________ ALL-NEW Yahoo!
