[Bluez-devel] hci_conn_info struct

[Bluez-devel] hci_conn_info struct

[Alexandros Karypidis]

Hi all,

I am using hci_conn_info to obtain a list of devices I am connected to. I 
"stole" the code from looking at what "hcitool con" does. What I want to do 
now is figure out what the CoD of the peer device is. I would like to do that 
in a smart way.

I tried doing an inquiry for devices, but I never receive the device I am 
connected to in the returned list of devices! Is this a limitation of 
Bluetooth or coincidence?

In any case, it seems a little silly to scan for devices in order to find out 
the CoD of a device I am already connected to. Is there a way to achive this?

Actually if you don't specify IREQ_CACHE_FLUSH flag to hci_inquiry() it will
return cached results and device you're connected too will be on the list for sure.

Not so. This presumes that I had previously inquired for information before 
the device connected to me. It is possible that someone may connect to me 
before I have a chance to detect him with an inquiry... :-(
