It runs now, well for an hour. This is simply a bug and will be fixed in the next release.
Not really sure of the value of a PAW without a DVB-T 

The only use I can think of is for attracting gremlins

I have run the test without a web browser connected to the PAW web server and everything has been running happily for over 5 hours, so I'm pretty sure that was the problem.

Thanks for all your help.

yes I can confirm I have been running the web interface alongside SkyDemon to keep an eye on things.

As I'm still waiting for the DVB-T dongle I'll try another test today without the web interface connected and report back.

tested using the laptop:
got the exact same results as with the tablet, connection to GPS and web server dies after about 1 hour but WiFi connection remains.

so it looks to be related to the PAW box or one of the connected devices.

Looks like it might be down to the amt of satellites that can be seen at any one time which is causing the gnss altitude to change?

I have the HT sensor attached to my PAW unit and the QNH seems to be wandering around from 1027 to 1034

I am between London City and Stansted who are both reporting QNH 1029 on the current TAF

Is anyone else seeing these wandering values on a HT baro board?

I have quite a long ribbon cable attached, I wonder if this might be causing an issue?

latest test using the tablet timed out at approx: 60 mins

first thing I noticed was an error in the web browser "Error prohibited CGI execution"

upon reload the message is:

ERR_CONNECTION_REFUSED

I have a suspicion the system is running out of file descriptors, but cannot see hiw at the moment.

do you suspect a file descriptor leak?

I'm trying to SSH into the PAW box so I can have a look to see how many descriptors are in use with user: pi pw: raspberry but I can't connect. Have the credentials been changed with the PAW o/s?

I found the error message you referred to, this us produced when it cannot open the file you requested, eg index.html

awesome

I have left the web client (chrome) open on the tablet but I am not sure if chrome is active and loading or not when skydemon is running, the multi-tasking on droid might be putting it into hibernation.

once the connection times out I have a look at the web server page. although last time I did check the web server page to notice the connection has gone wonky as skydemon was still quite happy.

Skydemon does seem to take quite a while to time out and report and error when it loses the GPS connection to PAW.

I am running mine now, with no dvbt plugged in, lets see if I see the same issue.
How long does it take before you cannot connect to 192.168.1.1 ?

about 20-30 mins IIRC.

I've just added the baro board so will be doing some more tests this evening and over night.

One datapoint here, please confirm, you do not have a dvb-t dongle connected, i wonder if this could be causing an issue ?

Yes the dvb-t dongle is not attached at the moment.

This could be the source of the problems. Hopefully Monday or Tuesday the unit will arrive and I can see if that gets rid of the issue.

PAW Ver: 20151030

I will try connecting from my laptop and repeat the test from power up on the PAW unit.

I have tried to connect to PAW using the laptop during the latest test when it disconnected, I can connect via WiFi but am getting the same error in a web browser:
"This web page is not available", "ERR_CONNECTION_REFUSED"

I've just had another GPS/PAW disconnection.

Steps/ order of events:
SkyDemon: "The connection to your GPS has been lost"

WiFi connection to PAW seems to be ok (checked in the WiFi settings of the tablet)

Web server is responding: "The server could not fulfill your request because the resource specified is unavailable or nonexistent"
Reloading the web browser later results in:
"This web page is not available", "ERR_CONNECTION_REFUSED"

Disconnected the WiFi from the PAW box, connected to my home internet hub then reconnected to PAW.

Web server is returning: "This web page is not available", "ERR_CONNECTION_REFUSED"

Does anyone else have a Galaxy Tab with 3g/4g?

I am wondering how the mobile data will work with PAW connected. I have tried using the smart switch setting but I seems to drop the connection to PAW when it can't use it to resolve web traffic endpoints, but I need to do more testing to be able to provide any meaningful feedback.

thanks Ian.

1) I have killed the PilotAwareAndroid App <- one less thing to potentially add errors into the mix

2) Good point, it can be a little confusing at first needing to swap connections, but pretty sure this is not the issue

Hi,

I've just put together my PAW (still waiting for the ADS-B dongle) and am currently testing. I am having disconnection issues and a few other weird things happening.

Test Environment
Tablet: Galaxy Tab S 8.4 WiFi + LTE
OS: Android 5.0.2
WiFi Dongle: http://www.ebay.co.uk/itm/231483794170?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
GPS: U-Blox7 USB dongle
PAW Ver: 20151030
PilotAwareAndroid Ver: 1.0

Bug Report 1:
Test case: Left Skydemon and PAW connected overnight.
Result: In the morning SkyDemon appeared to sill be connected to the GPS, green LED on GPS dongle flashing away happily as is the WiFi dongle LED, however the server was unreachable in chrome. After disconnecting WiFi from PAW and reconnecting I get the following error msg in SkyDemon:
"Failed to establish connection with Butterfly Connect Unit."
Cycling the power on the PAW unit and reconnecting are the only way to resolve the issue.

Bug Report 2:
Test Case: General use and testing
Result: Various times when PAW has disconnected from my tablet (for whatever reason) I have noticed it sometimes requires rebooting the PAW unit (via cycling the power) to be able to connect to the web server  again. I have tried to connect to the PAW web server from two devices when this bug appears and the results are the same: a blank screen or connection refused msg. All indications on the tablet show WiFi connection to PAW is okay but I am getting no data back.

Logs:
This set of errors are being repeatedly logged (which relates to the ADS-B receiver not being connected?):
SDR-USB: Attempting connection
SDR-USB: Error, connect()
