The only newbie problem I had is what to specify in -d argument. NetBSD examples specifying adapter name there, while FreeBSD does not accepts this. I have spent some time looking for my adapter BDADDR.

well, it kinda does. you can edit /etc/bluetooth/hosts file and add your adapter's bd_addr there, i.e.

00:11:22:33:44:55 mydevice

and then use -d mydevice with btpand(8).

I have done exactly the same, it just was not intuitive and differs from NetBSD as I understood it. It was probably the first time when I needed to know my adapter BDADDR.

and what name would you like to use? ubt0? something else? dont forget we dont create nodes under /dev for bluetooth devices. just netgraph nodes. i have plan to implement libhci (a-la linux bluez etc.) shim eventually :) if someone feels like beating me to it, i would certainly not object to it :)

Actually yes, ubt0. System reports it on boot, it is reported to the peered devices in hostname and NetBSD does so. IMHO it is not a bad choice from user's point of view.

Does actually this binding really necessary? rfcomm somehow works without it.

btw, obtaining bdaddr is really easy. in 99.9% cases (where there is only one bluetooth device connected to the system) 'hccontrol read_bd_addr' will do the trick :)

Indeed. But general number of BT tools, daemons and their options just making me sad.

PS: I have one small indirectly related, annoying problem. After some time of being unused Qtek goes to some kind of sleep, which makes it not responding on BT requests (both rfcomm and btpand), reporting "No route to host". After several retries or just by running l2ping and waiting for 3-5 seconds it successfully wakes up and working, but it makes using it a bit annoying. Is there any known workaround for it?

it depends. i'm guessing qtek device is probably putting idle connection into 'sniff' or 'hold' (or even 'park') mode to conserve battery life. you should be able to see what is going by running hcidump. in any case, it should be possible to add something that 'tickles' connection once in a short while to prevent it from going completely idle. it will drain the battery faster though.

It does not happens when connection is alive, only when connection establishes. So may be there some kind of timeout can be tuned, or device can be forcefully woken up in some other way?

oh, i misunderstood then. are you saying that initial connection setup is slow? if so, then i'm guessing your qtek device is maybe missing initial paging attempts. either this or something else is going on. when you do inquiry what do

Page Scan Rep. Mode Page Scan Period Mode Page Scan Mode

Page Scan Rep. Mode: 0x1 Page Scan Period Mode: 00 Page Scan Mode: 00

say for your qtek device? you can try to increase page timeout, i.e. 'hccontrol write_page_timeout' if your qtek device is timing out during initial page attempt (default timeout is ~5sec).

in any case hcidump that shows the problem would be a good start.
