I have successfully connected the IFLYGPS app (running on my iPad) to an iLevil 3AW (via WIFI) which is hardwired to a Trio EZ Pilot (autopilot). There was a "connectivity" issue between the iPad and the iLevil device. I did a lot of troubleshooting and exchanging emails with the folks at iLevil Aviation. They responded to my emails promptly, providing other suggestions to "rule in/rule out" possible issues. Came to the conclusion that there was some connectivity issue and I needed their "hands on" help for resolution. So I sent both the iLevil 3AW and EZ Pilot to then to assist in diagnosing the issue. They got the two devices talking to each other, in a day or so. I had them back here in about a week.
After re-installing the devices in my plane, they seem to work correctly on the ground. Now just waiting for a warmer day to go do a flight test.
In the IFLYGPS app, the NMEA sentences to use are GPRMB and GPGGA. They can be configured in the Setup Menu.
Menu>Setup>NMEA Output.
In the Levil Aviation AHRS utility app
Device Configuration>
- Configurable Options should be set to GDL90
- Serial Ports -- I am using Aux0 Port, Pin #11 (transmit), 9600 baudrate, "Auto Pilot" setting
In the Trio Ez Pilot, I am using pin number 7 (Data signal)
Levil Aviation really helped.
