Here is what our various ADSB messages mean:
1. No Heartbeat = iFly software is not getting any data from the ADSB device. This could indicate a config issue, or a problem with the WiFi connection.
2. Out of Range = iFly software is talking to the ADSB device, but the ADSB device isn't getting any data from a ground station. This could be normal (such as when you are on the ground) - but if it's happening a lot in the air, it could indicate an issue with your ADSB antenna. (Note: You may still receive air-to-air traffic data when this message is showing, but your wx data will not be updating)
3. Tower Idle = The ADSB device just recently stopped getting ground messages. This could be normal - either there isn't any new data to send, or you have descended out of range of the station. This message will change to "out of Range" after 5 minutes.
4. Receiving = All is well - iFly software is talking to the ADSB device, and the ADSB device is receiving data from the ground station.
