RE: [Bluez-devel] RE: Qualification testing - rfcomm

Marcel,

I just reproduced it here. Attached is an aclsession script which will do
it. First run aclsession on one machine, then run rctest on the other
machine. Also attached are the console output and hcidump from the machine
running rctest.

The pattern of send 5 packets, wait 20 seconds, send 5 more, etc appears to
continue forever. I'm told that it should just keep sending data.

-Daryl.

Marcel,

You're right that it doesn't check the error code, it just 
exits. But that doesn't explain why it sends 5 frames, waits 
for 20 seconds, and then sends 5 more.  Shouldn't send block?

I haven't yet tried to reproduce that behaviour.  So I'm not 
certain that the sequence of send 5, wait 20, send 5 repeats 
indefinitely.  I'll take a look at it shortly.

Thanks for the flow control patch...  I'll wait and see if 
anything comes out of the above stuff before sending it out 
for testing.

-Daryl.

Hi Daryl,

quoted

Finally got some results on those latest rfcomm changes for
qualification. Looks like there are a few more problems. :( 

 But we're

quoted

close. :)

TP/RFC/BV-09-C:
"Verify that the IUT handles flow control correctly when

the Tester,

quoted

acting as a device conforming to Bluetooth version 1.0B,

controls the

quoted

data flow using the Modem Status Command. The IUT's device

role is of

quoted

no importance."

The command and console output:

root@jack-00000000:~>./rctest -s -P 1 -b 20 00:A0:96:1F:83:71
rctest[351]: Connected
rctest[351]: Sending ...
rctest[351]: Send failed. Resource temporarily unavailable(11)

The IUT sends data in 5 frames, then stops for aboue 20s,

then sends 5

quoted

more, then stops, etc. Technically, this test passed 

because we did

quoted

quoted

stop sending data after the tester send MSC stop to the IUT. But 
something's clearly not right.

this looks quite right, but the rctest program don't check
the error code. If it receives EAGAIN it should try again, 
but it aborts.

Regards

Marcel
