SD crashes with PilotAware and lots of traffic

I have no knowledge of any traffic device generating more data than SkyDemon can handle.

decided to test some more
s‌at at home
o‌nly 3 or 4 contacts
t‌he text box "working offline" keeps popping up
a‌nd then it crashed
h‌ow can I get diagnostics/log to see what's going wrong?

Sounds plausible to me. Whilst in the air, your device will be using a huge amount of resources and power looking for a WiFi connection, to the detriment of running apps.

E‌dit ...which is why I always turn off WiFi when going flying!‌

Ah well! I don't have Pilot Aware, but in your case, the only option would seem to be to go into Offline Mode, as you have discovered. The odd thing is, if your device has established a WiFi connection with Pilot Aware, it shouldn't be looking for another connection. The only thing that I can think of is that the WiFi connection between your device and Pilot Aware is a bit flaky for some reason, which is causing your device to 'hunt' for a better connection. This is pure speculation on my part, since I am not an expert in such matters.

I'm afraid I have no idea what this means:

t‌he text box "working offline" keeps popping up

We will need screenshots and accurate descriptions of exactly what you're doing and seeing, if we are to help out. Certainly SkyDemon should never crash.

If you have changed SkyDemon's default settings such that it's trying to get live data when you're flying, you may wish to undo that change if you don't actually have an internet connection when you're flying.‌‌‌‌‌

Screen shot of "text box"
By mmcp42 - 6/27/2017 3:47:34 PM

And managed to get one while "flying"
By Tim Dawson - 6/28/2017 11:44:26 AM

The screenshot from when planning is presumably irrelevant since all your test cases are when flying, is that correct?

You're seeing the error because SkyDemon is attempting to contact our server but internet connectivity isn't up to it. We only try to contact our server when iOS tells us an internet connection is available. Perhaps there's a setting somewhere which means it still uses 3g to attempt to access the internet when you're connected to a wifi hotspot that doesn't provide its own internet? I read that some people have tried to do this using PilotAware. ‌‌

you may have put your finger on it
t‌est cases are when flying - correct
I‌ have a SIM card in the iPad so maybe it's sneakily trying to use that Smile
w‌ould also explain the amount of credit I got through this month
s‌o now SIM in flight mode

h‌owever, I did check "Live Data when Planning"
I‌ would have expected that to mean "only connect when planning, not when flying"‌
o‌r are you saying you will check for updates whenever there's an internet connection?

c‌heers‌
By Tim Dawson - 6/28/2017 2:43:08 PM

We only check for updates when there's an internet connection AND you're not flying (unless you've ticked that last option).

Presumably you were actually flying, and not just in Go Flying mode but sat on the ground? ‌‌
By Tim Dawson - 7/3/2017 2:37:38 PM

I'm afraid I do not have an answer for you. If SkyDemon is actually crashing, though, please contact customer support and they'll advise you on how to extract crash logs from your device to send to us for analysis.

I get it in both 'Live Data when Planning' and 'Live Data when Planning and flying'. I would expect to get it on the later, not both.

B‌TW it is possible to use the 3G and PAW connections concurrently if you have a 3G signal. Check the PAW forums for info‌.

SD V‌ersion 3.8.1.72
By Tim Dawson - 7/6/2017 1:44:39 PM

This issue is because the current PilotAware software advertises to iOS that it provides an internet connection, and therefore SkyDemon tries to use it. We try to use it when you're in Go Flying mode but when you're still on the ground, so not actually flying yet. We can't really solve it from our side without changing this behaviour, which we are not willing to do given the usefulness of getting the latest live data as you taxi, filing flightplans while rolling etc.
By Ian Melville - 7/6/2017 3:15:51 PM

Understood, is Lee aware of this?
By Tim Dawson - 7/6/2017 4:13:53 PM

Yes, there's a thread about it on his forum I believe.
By Ian Melville - 7/6/2017 10:33:05 PM

There is a thread about 3G/4G connection settings, but not sure there is one about it causing this issue in SD, though the two I suspect are related. I will add a bit to that thread tomorrow.
By Tim Dawson - 7/4/2018 10:46:56 AM

SkyDemon attempts to use the internet during flight if your device tells us there is an internet connection AND you have changed the default "internet usage" option to "live data when planning and flying". By default SkyDemon does not attempt internet access during flight even if your device advertises the presence of a connection.
By Russ_H - 9/17/2018 6:29:12 AM

Any plans for a switch to turn off the ability to recieve live data whilst in go flying mode?, I still get socket errors when closing Skydemon And pop up windows with the can;t connest to internet message on my Nexus 7 2013

I do all my planning before starting my engine.

when I got the original error (crashing) I was actually flying
f‌or testing I was sat on the ground but had clicked go flying
By mmcp42 - 6/26/2017 8:43:09 AM

been a fervent SD user for a couple of years
r‌uns perfectly on iPad using internal GPS
f‌inally got around to integrating PilotAware for trip to Project propeller yesterday
t‌raffic reported fine during positioning flight to Conington
b‌ut as I got closer to Gloucester, SD kept crashing
s‌ometimes after 30 seconds; sometimes after a few minutes

c‌hatting with a colleague on the ground, it was suggested that too many contacts generate more messages than SD can handle‌
h‌e also thought a fix might be in the pipeline to simply discard the extra data

a‌ny news?
a‌nything I should be doing?

I‌ have to say SD + PilotAware is just amazing!!!‌‌‌

Hi All, I just updated the PilotAware thread, I tested a patch from Lee and it fixes the data connection. With the fix I can connect to PA and access data via 3G/4G, no message from SD Smile

G‌uess this patch will be made public soon, keep an eye on the PA web site or thread,

I‌'m not part of the PA team just someone with the issue lucky enough to be selected to test the fix.

I've just tested a fix too, and it seems to work.

I've just added a Rosetta Piloy Aware to my Skydemon setup and now get this problem. I get the multiple warning pop ups of running offline and have had one crash with a socket error. It's quite annoying, what was the solution to stopping these warnings? I assume it's because Skydemon sees the wifi network that PAW has created and tries to download data from it but obvioulsy can't. Is there not a way it can detect the network is provided by PAW and not try to download from it?

Hi Colled
PilotAware does not advertise itself as a router, and hence the device should know that it cannot route traffic through this interface.
As far as I am aware this works on iOS, is your device Android by any chance

Yes it an Android tablet, Lenovo Tab4 8 Plus to be precise. The device does seem to know it can't route the traffic through PAW hence the error, but SD seems to still try anyway.Surely it can detect that the wifi connection is to PAW and not request internet traffic!?

Plus there is the annoying crash with a socket error, which seems to happen when stopping navigation.

By leemoore1966 - 7/4/2018 9:55:12 AM

Hi Colled,
I think we need Tim or one of his team to comment further.
I know in iOS he is able to gather debug information remotely, I am not sure whether the same facility exists in Android
lets wait and see.
Thx

By daerden - 9/4/2018 9:32:33 PM



These are the Messages I get. SD loses connection with PilotAware Rosetta, but finds it again instantly when attempting to reconnect. Also, I think that the connection through Safari is preserved (192.128.1.1). Live Data when Planning is selected.

Will try other settings next flight.

Thank you for the quick response, Lee.

iOS (iPad Pro)
* Display & Brightness
- Auto Lock: 5 minutes
- Lock/Unlock: activated
[But I was under the impression that this shuts off only the display, but I may be wrong]

* Battery
no sleep options available

Maybe Air Navigation Pro behaves differently, but I have not had the time to trouble shoot this.
