Hi list,

I need to someway estamate the distance between two bluetooth devices
already connected. I thought in using RSSI for this, but RSSI, as far as I
know, is not a mandatory feature of bluetooth. Besides, in the tests I have
made the scale of the RSSI measurements I got had not a good sensibility as
I moved. So now I am thinking on someway measuring the rate of
retransmissions for estimating this.

Well, my question is twofold: Does it make any sense the idea of estimating
the distance through the rate of retransmissions?? and, does anybody would
have some hint in this field??

Thanks in advance to any help!

Loreno
