Subject: [Bluez-users] rfcomm connection refused / Host is down (Again)

Hi!

I'm using the BlueZ stack in kernel 2.4.24, and I've got an usb dongle and I try to connect to an RS232-bluetooth attached to a robot's serial port.

So, I do hciconfig and I get
hci0:
Type: USB
BD Address: 00:0A:3A:50:20:15 ACL MTU: 192:8 SCO
MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:8280 acl:233 sco:0 events:233 errors:0
TX bytes:3096 acl:93 sco:0 commands:45 errors:0


When I do an hcitool -i hci0 inq, I can find the RS232 adapter, but on doing

rfcomm -i hci0 connect /dev/rfcomm0 00:c0:1B:05:C8:2A 1

I get a message with:
Can't connect RFCOMM socket: Connection refused
or either:
Can't connect RFCOMM socket: Host is down


Tom Chiverton asked if were the devices already paired.What do I need to do to pair the devices?

Oh! one more thing, if I do

rfcomm -i hci0 bind /dev/rfcomm0 00:c0:1B:05:C8:2A 1

The two devices get binded, but I'm still not capable to connect them!!!!

Can you help me??

Tank you!!!!!!

Albert

Thank you

Hi Albert,

do you really think that posting the same message again after 9 hours
makes any difference. Actually I am going to ignore such postings.

the question is if hcid is running and the PIN helper is working. Run
"hcidump -x" (as root) and show us what happens on connect.

Regards

Marcel
