hi,
i noticed that l2ping does not care about the timeout-argument.
running a current l2ping from bluez-utils-2.25 against a device that's
not available timeouts after 20 seconds regardless of any -t parameter.
pitti ~ # time l2ping -c 1 00:01:02:03:04:05
Can't connect: Host is down
0.00s user 0.00s system 0% cpu 20.527 total
pitti ~ # time l2ping -c 1 -t 10 00:01:02:03:04:05
Can't connect: Host is down
0.00s user 0.00s system 0% cpu 20.509 total
pitti ~ # time l2ping -c 1 -t 20 00:01:02:03:04:05
Can't connect: Host is down
0.00s user 0.00s system 0% cpu 20.515 total
pitti ~ # time l2ping -c 1 -t 40 00:01:02:03:04:05
Can't connect: Host is down
0.00s user 0.00s system 0% cpu 20.521 total
pitti ~ # time l2ping -c 1 -t 80 00:01:02:03:04:05
Can't connect: Host is down
0.00s user 0.00s system 0% cpu 20.513 total

you are mixing up the timeouts. What you are looking for is the page
timeout set through "hciconfig hci0 pageto". The timeout of l2ping is
the timeout between two packets.

Hi,
I'm not a 100% sure of the answer however i would say it is because
there are 2 timeouts:
- One is hardware based, and is globally configured at the device
level. It is the timeout for the paging procedure.
- the other is how much to wait for an L2CAP echo after you sent and
L2CAP reply.
Basically, the first timeout will be used when establishing a baseband
connection with a device, while the other will be used by l2ping ONCE
and only ONCE the baseband connection is up (which also means device is up).
I hope it helps :-)
Cheers,
Fabien
