[Bluez-devel] hcid vs. hciconfig hci0 up

[Bluez-devel] hcid vs. hciconfig hci0 up

[theresa g.]

I got my server app running on an Axis developer's board  83 with the use of 
an RFCOMM socket on channel one for the BT comm.  After flashing my board 
w/the new kernel (for BlueZ to work) I noticed I could not run the hcid 
daemon w/out the board either giving msgs about no kernel access to the 
device or even kernel panics when i put the hcid in a startup script.  (For 
those familiar w/this board, I can do a network boot of the same image and 
it all works fine)

I know this issue has nothing to do w/this list, but I wanted to know:

What is the difference between running the hcid and using "hciconfig hci0 
up" to bring up the device.  Since I cannot use hcid, I just use hciconfig 
to manually bring up the device and my app works fine.  Whats the difference 
between the two?  And is it better to use the daemon?

Thanks in advance,
Theresa

the hcid brings the device up and sets some more settings based on its
config file (for example name etc.).
