Correct, the latest version will fix your issue.
This is what's going on: if enough towers and traffic are coming in the bandwidth can be saturated, and some data can be lost (even in extreme situations this is usually <1%, so this is a benign issue). But the iFly had some unrelated logic to close & re-open the serial port when bad data was detected. But we found the Ping device doesn't recover from having the port closed. So it was a simple fix: We just don't do that for ping receivers.
Sorry you had to wait for an official answer. The forum's are not monitored as much if we're really busy, you can always contact support if you need a fast answer.
Thanks!
