I can tell my experiences as I was an original classic Skyview that recently upgraded to the HDX. My experience was the classic was more robust regarding WiFi connectivity. I rarely, had a WiFi disconnect with a IFD 540 and an IPAD with Foreflight connected. I only had numerous WiFi disconnects when I added another IPAD w/ Foreflight (2 IPADs) on the classic. Once I upgraded to HDX I began to get WiFi disconnects occasionally with the IFD and 1 IPAD. These are generally short duration and auto recover. Occasionally I must disable WiFi in Skyview and re-enable to fix. When I have IFD and 2 IPADs it will start WiFi disconnects within minutes. All have auto recover to date. I usually ask the copilot to keep their IPAD off.
I can add one more bit if information that I have reported elsewhere in this forum regarding Foreflight. I will always experience no textual METARS after approximately 1 hour of flight time or immediately if I took off without first having an update to Foreflight via internet. On a cross country flight I must look up weather via Skyview display. Foreflight is useless, all airports show ”no data available “. I have experienced this also with a Garmin system also. So, it is not isolated to a Dynon system. I know the data is somewhere inside Foreflight because I see the green/blue/red dots at weather reporting airports. Just tap the airport and it says “no data available “. This problem has been reported to Boeing / Foreflight last April. Still has not been fixed, but they say it is being “worked”.
