Lightbridge Latency - iPad 2 vs iPad Air 2

[lklepner]

I've been flying with a somewhat old iPad 2 attached the Lightbridge ground station and I knew I was experiencing significant latency due to the underpowered iPad but I had no idea how much exactly. I'd guessed around 1-2 seconds and planned to update to the latest iPad when the line was refreshed. Today I received that update - the just released iPad Air 2 - and decided to quantify the difference.

iPad 2 (2011) ~ 2800ms (yes thats 2.8 seconds!)
iPad Air 2 (2014) ~ 200ms

Both tests involved a GoPro Hero 4 Silver recording 1080p and ground station set to realtime mode. I used the apple stopwatch function to run the tests which displays two digits after the second so its only accurate to around a hundredth of a second.

ipad 2 latenncy is not 2800ms maybe on yours, What is your ios version? if ios8 u shouldn't have it on the ipad 2 anyways due to it slowing down the ipad.

Do you have an iPad2? What is your latency? I'd love to see some stats that show its a better performer for this particular task.

My iPad 2 is 16GB model with around 2GB of free space running iOS 7.
