Attached you'll find the code for a test program that makes a call using the hands-free profile connected to a cell phone and when the call is answered it generates echo (so the person who answers the phone will hear himself) Running just one instance of it with just one phone, it works great. When I try to run two instances, each connected to a different phone, it works for a few seconds and then all the SCO data stops flowing (hcidump shows nothing) The bluetooth dongle I'm using has a led indicating it's working. That led gets off permanently and the phones display an indication saying something like "bluebooth connection lost" After that, trying to do an hcitool scan dies with: Scanning ... Inquiry failed: Connection timed out On http://www.compendium.net.ar/2sco.hcidump.bz2 you can find an hcidump of the tests. The dongle i'm using is: Bus 001 Device 004: ID 4851:1103 horape@nb:~$ hciconfig hci0 version hci0: Type: USB BD Address: 00:0E:A1:00:54:19 ACL MTU: 192:8 SCO MTU: 64:8 HCI Ver: 1.1 (0x1) HCI Rev: 0x32e LMP Ver: 1.1 (0x1) LMP Subver: 0x= 32e Manufacturer: Cambridge Silicon Radio (10) horape@nb:~$ hciconfig hci0 revision hci0: Type: USB BD Address: 00:0E:A1:00:54:19 ACL MTU: 192:8 SCO MTU: 64:8 Build 814 horape@nb:~$ hciconfig hci0 features hci0: Type: USB BD Address: 00:0E:A1:00:54:19 ACL MTU: 192:8 SCO MTU: 64:8 Features: 0xff 0xff 0x0f 0x00 0x00 0x00 0x00 0x00 <3-slot packets> <5-slot packets>

Kernel is: Linux nb 2.6.17 #4 SMP PREEMPT Wed May 10 13:53:45 CEST 2006 i686 GNU/Linux Default with KNOPPIX 5.0.1 2006-06-01 I'm working on a toshiba satellite P105-S6024. The phones i'm using are sony ericsson z520a. The code assumes rfcomm chann= el 3 is hands free profile (line 50) and call indicator 10 is callsetup (line 67) Is somebody able to help? Is there more info I could provide to help in the= search for a solution? I'm looking forward to have 7 phones connected to a PC, making calls all at once almost 24/7. Should I try with 7 dongles, one for each phone? Would that work better? Thanks! HoraPe --- Horacio J.
