How does it work?
When you turn on RSSI recording AirYarde starts an Android service that listens for RSSI change broadcasts sent by the OS. I suspect Android does not broadcast every change to RSSI, it likely waits until some range is surpassed. I am thinking about creating an "active mode" option that samples the RSSI every second. That would use more power, but it might be worth it for many of you. Stay posted for more updates to AirYarde.
