hcitool cc .... connected and drop

[Ed Tsang]

Hi, 
I am trying to use hcitool to create a connection. The connection seem to be connected and dropped right the way.
Looking at the hcidump, look like the connect command is ok, but then there is a "read remote supported feature", "read remote name" then a "disconnect command".  
I tried to search "hci_read_remote_features" or usage of "OCF_READ_REMOTE_FEATURES" and put in debug print on all functions but could not figure out where the "read remote supported feature" was called from the "hcitool cc" command.
Anyone please point me to the trivial stuff.

Regards, 
Ed

the Linux kernel does that for all completed connections

Thanks, Lain.

>the Linux kernel does that for all completed connections
I am still very "green" to bluez and linux. Is there a place where I can look into the bluetooth related kernel codes? 
Is the disconnect command came from the kernel code too?

Cheers, Ed

I don't think there is any API documentation, but the kernel sources can
be seen at many places on the internet, such as

  http://lxr.linux.no/#linux+v2.6.32/net/bluetooth/
