A couple of times now I've got a pop-up dialogue saying "Flarm data invalid" along with a flarm data string displayed. Clicking to acknowledge this results in the program going back to planning mode.  This has happened on the ground before take-off only and not in the air (so far at least).

Interesting enough I was playing with the set-up in the house with both the tablet and my PC connected to the Airconnect and Skydemon running in navigation mode on both.  Both were using the current latest version - 3.13.3  When I got the error on the tablet the PC continued quite happily with the data with no errors.

If it is a checksum error on a data sentence please, please, please could you just dump that sentence and continue on to the next. I don't really want to know about what is probably a single bit error in the data transfer.  If there are multiple or frequent errors then by all means put up a warning or refuse to use the data stream.  Yes it shouldn't go wrong... but it obviously can do. 

Thanks.
