Hi, I'm using the bluez implementation for a prototype I developed for my thesis. Therefor I would need to know how the link quality is calculated (or at least its unit) when calling "hcitool lq <bdaddr>". I looked into the hcitools bluez provides but only got as far as hci_read_link_quality. Probably someone can give me some infos on the calculations or a direction where to look at.
Thanks for your help
Regards
Guido

if you read the Bluetooth specification, then you see that this is
vendor specific. It depends on the chip manufacturer.
