[Bluez-users] Samsung T809/D820 association issues.

Hi,

I am having trouble getting my Samsung phone to permit my linux box  
to use it as an rfcomm device.  The phone in question is a Samsung  
t809.  From what I can tell, the phone attempts to authenticate to  
the computer with the pin I gave it, it then successfully pairs, and  
tries "Getting a service list...".  This is where things go wrong.   
The phone errors out with a "Service not found".  It then refuses to  
permit me to authorize the computer to use it as an rfcomm device.  I  
think it the latter has everything to do with some flawed logic that  
the phone designers had that if it gets a "Service not found", it is  
not really paired with the device.  Attached is an hcidump output,  
perhaps someone more intelligent than myself can enlighten me on what  
I can do to handle this situation?  Thanks!

I only see connections from the phone to your Linux box and thus it is
totally okay that it asks for supported services and disconnects if it
doesn't find any. Establish the connection from the Linux box.

When I try to get the computer to initiate, I get a "connection  
refused".  Attached is the hcidump output of an  "echo ATZ > /dev/ 
rfcomm0" , which does result in "rfcomm0: connection refused".  I did  
"Authorize" the linux box from the phone's menu, so I'm still  
somewhat confused as to why it's denying.  Thanks again.

check with sdptool what services the phone supports on which channels.

Hi,

Thanks for pointing me in the right direction.  I found the proper  
channel.  I do however keep having to delete my linux box as a device  
from the phone in order for it to keep permitting it, even if I  
'authorize' it.  I have a sneaky suspicion that this is due to the  
poor modification of the original D820 firmware to create the T809  
firmware.  That, however is another problem for another list.  Thanks  
again for your help!
