Speaking specifically of the AVRT7 Plus, what I see with my lights.toggle quoted messageShow quoted text
Left red - constant once powered up.
Left blue - flashes each attempt to connect to wifi. No blue at all once wifi is connected.
Right red constant while waiting to connect to the server.
Right red - slow flash once connected to the server.
Right red fast flash - decoding
Right blue? - never seen blue on the right side that I remember. I was always on the sending end while trying to get the internal to decode.(May be internal receiver decode) I tested each of the three units when purchased over the last year and the results above were consitant.
Receive testing info. I tried a number of receive antennas and could only decode packets within a close proximity (a few blocks) with an outdoor 5db gain roof mounted antenna. Once I connected to a mobile radio (same antenna), I am able to decode packets from 100+ miles away. A scanner or something like that might be cheaper if you only want a receive only I-gate.
Another option for testing is to connect with Putty or similar. That will show current status. Usually decoded packets and or a repetitive wifi attempt indicator. It gives set up info at first but it goes by pretty fast and is easily missed while connecting. There is a video on YouTube for this.
