My ECHO Uavonix adsb is working very well and I have a clean Bill of health from the FAA test I ran. Of course, I had a pass when I ran the PAPR wuth Navworx also so don't know what this proves.
Here is a tip for anyone using the ECHO set up app.
Set up of the ECHO ADSB is simple using the ECHO app I got from play store.
However, I found that I could not use it while in flight...or on the ground when IFLY is on.
Found out from Uavionix that when you have IFLY on it will not let anything else access the WiFI on your phone or tablet.
Not a big problem, but nice to know to prevent unnecessary troubleshooting.
