Hi ! >From the CC2420 datasheet : P = RSSI_VAL + RSSI_OFFSET [dBm] Where RSSI_OFFSET = -45 (found empirically) and RSSI_VAL is the value from the strength field as a signed 8 bit integer.
You should take a look at the datasheets of your hardware and the archives<http://www.tinyos.net/scoop/special/support#mailing-lists>of this list. :) Mathieu On 30/10/2007, Venkat Manoj <[EMAIL PROTECTED]> wrote: > > Hi All, > > I am trying to convert the TOS_Msg->strength value obtained from TelosB > motes.
