 Hello, Maksim!  
   
 First of all thank yoy for your kindness.

 I have read a very old manual, nothing was stated there about sdpcontrol.  
 Right from now I will know about this tool :)

 Fully agree! I have figured it out in experimental way, while writting my own script to enable bluetooth service at startup :)

 Again, thank you for a nice hint.

 Sorry, I have forget to tell, that both sdpd and hcisecd are started without problems.

 semi-works...  
   
 OPUSH sessions work. I can do "getdefault" and put my own contacts  
 But FTRN does not work completely. Here is my log:

 Also I have tried to connect to my Motorola v600 phone, but without success. I can successfully upload files to it using OPUSH,  
 but cannot download files. For any my action (using OPUSH and FTRN) I receive Forbidden(0x43) response. Maybe the cause is Motorola's  
 implementation of those protocols? Or some kind of security on the phone? In nearest future I will try to use my phone as GPRS modem.  
 of OPUSH?   
   
   
 Bye!
