Hi,
We wanted to do some experiment about RSSI using the Estimote App (from the iTunes Store), and the RSSI values I read are in dB unit.
From what I understood RSSI is a measurement of power of received radio signal, so we should be able to get the power in dBm or mW from the readings. Right now I am trying to find out the relationship between received power and the distance, using the same transmit power (which is set to -12dBm at this moment).
We have recorded the RSSI readings at various distances, but the RSSI value is in dB as the app shows. This seems to be a relative value and not the power in dBm. So I would like to know if there is a specific formula to get the received power (in dBm) from the RSSI reading.
Thanks!
