[Bluez-users] Concurrent hcitool commands

["J. Carlos Alvarez" <jcalvar@movilok.com>]

Hi, we are trying to use hcitool to retrieve some information about =

several devices and we need to do it in parallel (several scripts =

concurrently call "hcitool name XX:XX:XX:XX:XX" using the same local =

device looking for the name of several remote devices).

Doing this we found that some responses received from different remote =

devices were mixed, we obtained the same device name from two different =

remote devices.

The following is a simple way to check this behaviour:
---------------------------------------------------------------
[root@localhost~]# hcitool -i hci0 name 00:12:D1:DB:9A:E3
Nokia E70
[root@localhost~]# hcitool -i hci0 name 00:13:FD:FC:DE:50
Nokia 6680
[root@localhost~]# hcitool -i hci0 name 00:12:D1:DB:9A:E3 & hcitool -i =

hci0 name 00:13:FD:FC:DE:50
[1] 14223
Nokia E70
Nokia E70
[1]+  Done                    hcitool -i hci0 name 00:12:D1:DB:9A:E3
---------------------------------------------------------------

- The first command gets the right name of our E70 phone:
 "Nokia E70"

- The second one also gets the right name of our 6680 phone:
 "Nokia 6680"

- But if we invoke both commands concurrently, both "hcitool" calls get =

the same name as the device response:
 "Nokia E70"
 "Nokia E70"

Are we doing something wrong?

Is there any technical limitation related to this kind of requests so we =

must to do these calls serially?

Is this a bug?

Thanks in advance,

Juan Carlos
