[Bluez-devel] Inquiry result with rssi in bluez libs 2.7

[Bluez-devel] Inquiry result with rssi in bluez libs 2.7

[Rognlien Dag Kristian]

Hello,

I see that hci.h has

#define EVT_INQUIRY_RESULT_WITH_RSSI  0x02

The bluetooth 1.2 spec defines this event code as 0x22

Is this a typo, or is there a reason why it is set as 0x02 in hci.h?

this was a stupid typo and fixed in CVS now. Thanks for finding it.

While I have your attention on this subject...

In the hci_event.c in net/bluetooth the hci_inquiry_result_with_rssi_evt
function just ignores the rssi value, and files the values of a normal
inquiry_info struct. Is there a plan for how the rssi values should be made
available to the user mode application calling ioctl with HCIINQURY? As far
as I can see there are now way for an application to get this value now.

go ahead and write a patch for the Bluetooth core to store the RSSI
value so first it will be exported via /sys in the inquiry_cache. Then
we can think about adding an ioctl that is capable of handling the RSSI
values.
