[bluetooth-dev] abuut bti and btdm



Hi! Hi!,
       I wanna ask about the bti and btdm. ppl tell me that the btd s an old 
version and already obsolete. but when i am using bti and btdm, which is the 
correct version, it said HCI failed to initialize and "waitpid sdp server : 
NO child processes". could anyone tell me what's happened???
the log is as below:
