This lesson is to give an example on how to get Rssi readings from incoming packets. It consists of two applications:
- a simple application that periodically sends messages over the radio, and
- a modified version of BaseStation that includes the Rssi data on the payload of messages received over the radio before forwarding them over to the serial link.
Currently, this demo works only for motes that use CC1000 or CC2420 radio transceivers, but it should contain enough information for porting it to other chips that provide RSSI in a similar manner.
Introduction
RSSI is an acronym for Received Signal Strength Indication. It is a measure of the signal power on the radio link, usually in the units of dBm while a message is being received. It can be used for
