Hello,

When I try to open 3 RFCOMM connections from the same device to 3 remote ones, the first connection is OK but the 2 following give a "Error: Command Disallowed". I suspect an incorrect bluetooth parameter in my hcid.conf (lp ? lm ?)

Any hint is welcome !

PC is running a 2.6.23.12 Kernel with BlueZ 3.23

hcidump & hciconfig are below if it can help !

Thanks a lot,
Oli

This is probably because you start the creation of the new connection 
before the previous connection request is completed. CSR Chips do not 
allow multiple connection setups in parallel. So either wait with the next 
connection setup until the previous is compledet (either success or 
failure) or retry the connection setup when you get command disallowed 
(and it may be a good idea to sleep some 100 milliseconds before 
retrying). 

Ciao,

Peter

actually the 2.6.23 should be able to handle (queue) multiple HCI
connect requests. I would nee the output of "hcidump -X -V" to see what
is actually going on.

Regards

Marcel

Thanks a lot for your answer Peter,

Sorry if my question is stupid, but do you know if there are other bluetooth 
chips used in common dongles that would support multiple connection setups 
in parallel ? This way I could to find one of them and test it ;)

I use a simple socket "connect" to perform my connections, and having a look 
at my hcidump it seems that the low level layer is retrying the connection 
by itself, without actually leaving the "connect". Not sure how this retry 
is performed though, and how to tune it ?

I will provide you with complete hcidump tomorrow morning as Marcel asked.

Best regards,
Oli

Hi,

I have tried parallel connection requests with 2 types of dongles :
- Cambridge Silicon Radio (CSR) one is successful for the first connection, 
and, as Peter said, returns "Command Disallowed" for next ones (and there 
are automatic retries)
- Integrated System Solution Corp. one allows all connection requests (no 
more "Command Disallowed")

However, I can notice that the "HCI Event : Connect Complete" event is long 
to come back, even if all connection requests have been performed at the 
same time. For example, trying to connect concurrently to 5 devices from the 
same dongle (with a simple "connect", sleep 10 seconds, "close") gives 
something like :

00:19:2D:15:FF:0E : 3 seconds between Create Connection (0x01|0x0005) and 
HCI Event : Connect Complete
00:12:D1:6E:4C:96 : 6.7 seconds between Create Connection (0x01|0x0005) and 
HCI Event : Connect Complete
00:16:4E:83:2D:19 : 6.2 seconds between Create Connection (0x01|0x0005) and 
HCI Event : Connect Complete
00:12:D1:65:27:7F : 9.1 seconds between Create Connection (0x01|0x0005) and 
HCI Event : Connect Complete
00:17:B0:1E:54:FD : 11.5 seconds between Create Connection (0x01|0x0005) and 
HCI Event : Connect Complete

Of course, concurrency seems to be the concern, trying to connect to each 
device at a time is always performed instantly.
Trying to span these connections on several bluetooth dongles (i.e. 
00:19:2D:15:FF:0E on hci0, 00:12:D1:6E:4C:96 on hci1 etc...) is not 
improving the connection time.

Any help is welcome ! I really wonder what is blocking here !

I'm running Kernel 2.6.23.12 and BlueZ 3.23

Here is a full hcidump ...

not seeing the "Command Disallowed" doesn't meant the connection request
is not queued. It is impossible to have two (or more) baseband pages at
the same time. You only have one radio in the chip. Once that is busy
with a connection attempt, then everything else has to wait. So if the
host stack queues these connection attempts or the link manager inside
the Bluetooth chip makes no real difference.

Regards

Marcel

Marcel is perfectly right. The Radio/Baseband is a shared resource and 
busy when setting up a conection. So all connection attempts must be 
serialized. The only way to speed up the process may be to do an inquiry 
first, so you know the clock offsets for the different devices. Knowing 
the clock offset usualy makes connection setup a lot faster. If I remember 
right BlueZ caches the clock offsets and uses them in a connection request 
if available. However, the connection setups still need to be serialized 
(either inside the Bluetooth chip or inside the stack).   

Ciao, 

Peter

Thanks a lot for your explanations guys everything is clearer now.
However, I can't understand the following behaviour : instead of starting 4 
connections from the same hci device, I put 4 dongles and start 4 
connections at the same time one per dongle.
Here is what I get -dump below- (basically 2 "quick" connections, and 2 page 
timeout). It can vary depending on attempts, but at least 1 page timeout.

Do you think running the inquiry on hci0 (for example) would "save" the 
clock offsets for connections on other dongles ? (I mean inquiry on hci0 
then "connect" to the found device on hci1 to N) ?
Do you thing there is there another way to speed this up (e.g. doing a 
request name to the remote device on the dongle where the connection will be 
done) ?

Thanks again & best regards,
Oli

Hi Olivier,

That's probably because the "air" interface is also a shared resource. 
When multiple devices are paging at the same time you'll get collisons and 
corrupted data packages which may cause random page timeouts.

No. The clock offset is only valid between any two devices.
A third device will allways run on its own internal clock. May be if you 
know the clock offset between, lets say HCI0 and HCI1 than it may be 
possible to calculate the clock offset between HCI1 and a third device if 
you know the clock offest between HCI0 and the third device. Never tried 
that.

No, all this stuff is handled in the baseband and not a BlueZ issue. 
A name request is more or less the same as a connection setup, that won't 
help. 

Ciao,

Peter

Indeed, maybe will I try to put my dongles in a hub allowing a bit of 
distance between each other. Having them too close is maybe not a good idea. 
Using class 2 ones instead of class 1 may not be bad as well, I suppose the 
more powerful the more "air" problems. What's your opinion about all of this 
? Another point : have you ever had USB / power issues when using several 
dongles ? I was wondering if a lack of responsiveness of power supplying 
when more power is required for some operations could not cause troubles (I 
mean the delay between "I need more power" and "I get it"). If I'm talking 
nonsense don't hesitate to flame me.

Thanks a lot for your help, I think things start to be clearer to me !

Best regards,
Oli
