[Bluez-users] scanning possible, but no l2ping?

Hi,

My problem with my two bluetooth adapter is, it's possible to scan the
area und I get the right result, but it isn't possible to execute l2ping?
I've a desktop computer and my crappy linux watch ... only with the
desktop i've hcidump yet.
I hope it is something with the config wrong?!

Franz

you set your desktop device into security mode 3. Is this what you
really want?

It seems that hcid is not running, start it.

Securty Mode 3 is not safty, isn't it ;) My problem is, I need a f***
connection between Watch and computer for a special live-demo in a
closed lab.
And the next problem is that pairing doesn't work with the watch, so I
turned everything off. So all I need is just a connection to send tcp
packages - I don't care about the secury.

... hcid is running ...

[root@dervish root]# ps -afe | grep -v grep | grep -i hcid
root      2374     1  0 19:46 ?        00:00:00 hcid: processing events

the security mode 3 is not more safe than security mode 2.

You must switch "auth" and "encrypt" off on _both_ sides. If one device
is in security mode 3 than the other must follow. This is how security
mode 1 is definied in the specification.
