The applican can receive an > event each time the device is inquiried? No, unfortunately that can't work with an ordinary inquiry. The device which is scanning only receives an ID packet, which contains no information about the sender. There are moves afoot to add more flexible forms of inquiry to the specification, but that hasn't happened yet. pws ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

The applican can receive an > event each time the device is inquiried? No, that is not possible in general. The bluetooth chip responds to the inquiry without generating any HCI events. You can see SDP requests, since those are handled by the Bluetooth stack, but that won't help you much I guess. Maybe there are vendor-specific commands to make that possible, but I don't know about any.

In the inquiry procedure at the baseband no identity information flows from the inquirer to the scanner. The only thing the scanner can tell is that somebody has inquired. As an analogy, inquiry works like this. The inquirer sends out a message which means "Can anybody who can hear me identify themselves" and gets responses like "I heard you, I'm 0x123456789abc and I'm a headset". Hence, the inquirer knows the identity of the devices that have responded but the scanners gets nothing from the inquirer. Future changes to the inquiry spec might allow extra information to be passed from the scanner to the inquirer, but not from the inquirer to the scanner. If the scanner responds to the inquirer and then the inquirer follows it up with a remote name request or an HCI level connection then at that point the inquirer reveals its address. In the former case, the information is available at the baseband, but is not passed up to the host. In the latter case, the host is informed of the address of the device that has connected. However, completely passive identification, as you describe, is not possible. - Steven ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
