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

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.

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
