[Bluez-users] Multiple connections between USB dongles

Hi

I'm using Broadcom based dongles.

I'm using hcitool cc <BD-ADDR> to connect to other bluetooth dongles. The
problem is, at a time I can have only 2 connections. To connect to a third
dongle I have to kill one of the 2 earlier connections. Any idea why this is
happening?

Regards
 Arpit

run "hcidump -X -V" and look for the actual error message.

Hi Marcel

This is what the hcidump returns

< HCI Command: Create Connection (0x01|0x0005) plen 13
    bdaddr 00:10:60:B3:2D:04 ptype 0xcc18 rswitch 0x01 clkoffset 0x0000
    Packet type: DM1 DM3 DM5 DH1 DH3 DH5
> HCI Event: Command Status (0x0f) plen 4
    Create Connection (0x01|0x0005) status 0x0c ncmd 1
    Error: Command Disallowed

and what does "hciconfig hci0 revision" tells you about the firmware
version. Maybe they only support two ACL links at a time.
