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.

Hi,  Following Alastair's very kind and patient advice I changed my very unreliable Airconnect for the WA-232E Alistair mentioned.  I have a PowerFlarm portable connected to SD on an iPad via the wifi adapter WA-232E.  I haven't done a lot of flying with it yet but so far it has proved 100% reliable.  It has the added advantage that you can have up to 4 devices connected to the WA-232E, so I have a the PowerFlarm connected to my iPad and also to my iPhone which I use the full screen traffic radar falicity on SD for mobiles.  Another advantage is that the WA-232E can be battery powered so I don't have to start the engine before configuring my PowerFlarm portable and SD for the flight.

On a related matter mode C/S traffic is no longer displayed on my SD although it is still shown on the screen of my PowerFlarm portable. This seemed to have stopped around the time of the last upgrade of SD.  I have double checked all the settings on SD and my PowerFlarm to ensure that will all allow the display of mode C/S traffic on SD (again this was working late last year).  Using a telnet session I have collected logs of the sentences coming out of my PowerFlarm data port and sent them to SD and Flarm, but unfortunately no fix yet.

I was just wondering if anyone else has seen this problem?  I am aware of one other pilot who has experienced the same problem.
