Hello Stefano, hello all
Thanks for discovering that bug!
I guess the fix is as simple as adding a conversation3Way.notifyAll();
in DriverCC2530.unLock3WayConversation()
But after looking into the locking code, I wonder why the locking is so
restrictive. If I understand the 3waylock code correctly, it doesn't
allow to have two same requests on the air at the same time. A response
is waited for at most the TIMEOUT time which should be > 7.5 sec in HA
networks.
Suppose you have 10 sleeping devices which wake-up every 7.5 secs and
you want to send them each a value. You will have a mean waiting time of
3.75 secs for each requests so the whole cycle will take nearly 40 secs.
(even if you do it with 10 threads)
What is the reason for not letting several requests out at the same
time? I suppose we can triage the answers correctly (see bugs #275 and
#276).
Regards Philipp

Bug #277: Deadlock when multiple thread try to send the same request
<http://zb4o.aaloa.org/redmine/issues/277>
* Author: Stefano Lenzi
* Status: New
* Priority: High
* Assignee: Stefano Lenzi
* Category: zigbee.CC2530.driver
* Target version: org.aaloa.zb4osgi.zigbee.CC2530.driver-1.X
* Has a patch: No
* Has license agreement signed: No
When multiple thread try to send the same request by means of
*DriverCC2530* (i.e.: both of them invoke the method
/sendZDOIEEEAddressRequest/ ) then the one that will be set in the
wait state due to the /waitAndLock3WayConversation/ will never be awaken.
