the message i got from hcidump is:

>ACL data: handle 42 flags 0x02 dlen 12
L2CAP(s): Connect req: psm 4097 scid 0x0040
< ACL data: handle 42 flags 0x02 dlen 16
L2CAP(s): Connect rsp: dcid 0x0000 scid 0x0040 result 4 status 0
Connection refused - no resources available

then it starts disconnecting this device.
connection 3 devices works good, and i can send messages to every of them.
but connecting 4 or more will refuse the connection. "no resources
available", what does that mean? how can i fix that?


Gr,
mark

No quite sure but it is a problem with your BT chip. It only allows 3
connection. If it is a CSR chip may be soembody has configured it to allow
only 3 ACL connections. You can find out using bccmd. There is a PS-key
named something like MAX_ACL_CONNECTIONS.

Ciao,

Peter

No. It's not a baseband issue. If it were, the connection would be
rejected at the HCI level. Instead, the connection is being rejected at
the L2CAP level indicating that the baseband was happy to accept the
connection, but something that's nominally in the host has rejected it.
