Hi Tim,
Ever since the latest SD update where the connection to PF was moved from CONNECTIONS to GO FLYING, I can't get my PF Core to connect to SD and I have to revert to Use Location Services and the iPad's internal GPS.
I have checked the PF Core device and get the customary orange LED for 20 seconds and then the steady green LED which tells me that it has booted correctly and is receiving GPS signals. On the iPad wi-fi status icon, it shows that I am connected to the Butterfly Connect.
I have confirmed SETTINGS - CONNECTIVITY - FLARM and when I select GO FLYING - USE FLARM, I get the message: "Please wait while a connection is established to your external device" but after about 10 seconds I always get the message: "Failed to establish a connection with Butterfly Connect."
I have tried it with airplane mode off (wi-fi still selected) and on; I have deleted SD from my iPad and reloaded it; I have reconfigured the PF Core with my USB stick but all to no avail. My iPad is connected to the Butterfly Connect wi-fi and the PF Core is receiving GPS data but it's just not happening on SD and only seems to have started after the last update.
Do you have any suggestions, please?
Paul

+xSeems to me that neither Power Flarm nor Sky Demon is the problem but your Air Connect, which occasionally sends out spurious signals and is, therefore, rejected by SD during its checks that the data is valid. Why should Tim have to deal with 'garbage in' when other connections don't have the same problem? Hmmm...but why does that garbage works fine whith other software?

I can't answer that, Peer, but I think I would rather have a device that I know ONLY works with valid data, rather than a device that POSSIBLY uses corrupt data. What else is that other device hiding from you if it's prepared to use data that does not pass check sums?
As I said before; this is an Air Connect problem, not a Sky Demon problem.

What do you think are CRC check sums for? Swithing off your computer? Or to give the soft/harware the chance to handle NORMAL ereos? Transmitting data wireless is never 100% error less.
I thing fault tolerance is a helpfull thing. As in real ife as in software coding, isn't it?

Well, next time you use Internet banking and you send $10 000 but only $1 000 is received then you can blame the same thinking as yours. If I get a problem with an app on my computer then it stops the app. It doesn't shut down the computer. Does the Air Connect problem actually cause SD to shut down your tablet or does SD just stop working. I'm not an expert, no, but I do know about GIGO and you're expecting Tim to just accept GI and adjust his app to account for that. Air Connect shouldn't be outputting faults......it's as simple as that.

Air Connect shouldn't be outputting faults......it's as simple as that. Hi Paul, ok, you are right! Not a good example. Sorry for that. Let me try to explain it with an other exaple. Let's say SD were an email client. From time to time there comes spam with your mails. What do you thing is the best way to do? Stop working the App? Asking for a mailserver don't sending spam?
Or just give a massage that there ist a spam mail?
BTW: The air connect only fowards the data it gets from the device via RS232 protokol (serial) and unfortunately it is normal that there are errors from time to time. That was no problem the last 30 years as HW and SW can handel them.
In case of SD the worst case is when the navigation suddenly stops. That is definitvly not good for safty.
And if you ever used a FLARM, you will understand why i would never fly without it again.
I love SD, yes, but if i had to decide, the the FLARM has the higher priority. As i mentioned other flight navigation apps can handle the faulty data and providing a working and safty system without sudden stoping navigation.
I hope SD will be willing to find a solution. Do not make a phillosophy of that problem. Just let us fly in safty. PLEASE!
Live could be soooo nice.
