Re: [Bluez-devel] "ACL Connection Already Exists" while using only DBus calls

[Pierre-Yves Paulus <py@idlum.be>]

Hello again,

I forgot to mention 3 things in my last message about the same subject:

-the last signal received about the device I want to connect to is a 
"RemoteDeviceDisconnected", and no "RemoteDeviceConnected" signal has 
been received afterwards.

-this is confirmed by the output of a call to adapter.ListConnections, 
which tells that no connections exist at all.

-Sometimes, the error I get (exactly the same circumstances) in hcidump is

   < HCI Command: Create Connection (0x01|0x0005) plen 13
       bdaddr 00:60:57:4F:EB:37 ptype 0xcc18 rswitch 0x00 clkoffset 0x0000
       Packet type: DM1 DM3 DM5 DH1 DH3 DH5
   > HCI Event: Command Status (0x0f) plen 4
       Create Connection (0x01|0x0005) status 0x09 ncmd 1
       Error: Connection Limit Exceeded


So for me it clearly looks like a bug. What can I do to help get it fixed?

Regards,
Pierre-Yves
