Technical Support / Re: A Bug or Not S/D to FLARM Connection

« on: July 23, 2017, 05:20:31 pm »

After some more tests, I found the problem. I had set a static IP address with PAW to use my iPad using internet connection coming from my iPhone (paired via Bluetooth). In this configuration SD doesn’t find GPS position. If I set a dinamic address (DHCP), SD works. The question now is: how to have at same time PAW data and internet connection ? In my iPad I don’t have a SIM.
I have understood a SD forum thread well, may be now (with last update) PAW send only gps data, allowing SD reciving internet connection via bluetooth?

Thanks

I have the same problem. SD doesn’t work setting PAW connection. I am running SD 3.8.2.77 (I am a beta tester). Using FLARM it works.

What power setting do you have for the wifi ?

Thx

Hi Lee

How can I verify the Wi-Fi power setting?

Thx

I have had similar issues in the past, albeit with an Android tablet not an iPad. Since I reduced the WiFi power to 20mW, the problem seems to have gone away - and I have about a metre between the PAw and the tablet. 100mW is the maximum permitted power for a domestic WiFi router @2.4GHz and should be good enough for a range of more than 50m. Airliners excepted, few aircraft are that large, and having too strong a signal can cause more problems than it solves due to overloading of the receiver.

From a network point of view, if you want a reliable network connection, TCP is much better than UDP, but you do have to re-connect in the event of a loss of signal. Personally I would prefer SkyDemon to implement auto-reconnect rather than drop to using UDP.

Hi,

How did you reduced the WI-FI power to 20 mW? I should like to try this option.

Many thanks

Hi,

An update. Yesterday I had 5 flights for a total of 7 hours flying.
In the first twos I used iPad connected to PAW; I loose the GPS signal one time.
In the last three I used iPhone connected to PAW; I loose the GPS signal two times. In the last one I did two attempts before having SD again running in FLARM mode.
In both cases there were no other Wi-Fi connection.
Unfortunately I did't monitor the GPS connection (I did some mistakes using Telnet Lite or, when the problem occurred, the connection was lost and no tracing was saved).
I am sure it's not a Wi-Fi problem, the connection is always on.
I use the recommended power supply to feed PAW.
I have some other pilots asking for me how PAW works. Honestly I don't know what to say; this problem is really boring, in the past using internal GPS I never had any problems.

Sounds like the problem is with the iPad trying to connect to other connections or otherwise losing connection. Can you change your Wifi settings on the PAW, to try various combinations of wireless B or G, with various powers? I had a problem a while back where I used to lose connection if my tablet was too close to my PAW. With one lot of experimental settings it would only work when the two were nearly 2 metres apart or further.

Rogerthedodger, can you try various Wifi settings as well?

I have my PAW fixed behind the mount where is the IPad. Do you think could be this the problem?

Hi Max

Alan raises a good point
Do you have your iphone set to share its internet connection?
If so your ipad could be switching connections between Pilotaware and your iphone

If you want to share your internet connection from iphone, you can do this over Bluetooth instead of wifi

Thx
Lee

Hi Lee, my configuration is:

IPad, no SIM card, connected via WI-FI to PAW
IPad connect via Bluetooth to iPhone with SIM card and internet connection

However I have tested iPad connected via WI-FI to PAW with no other connection. The problem occurs random in both cases.

To give you more information I have also tested iPhone connected via WI-FI to PAW running radar screen on the browser. In this case I have never lost my PAW connection.

How often are you having this disconnect?

Also can you try an experiment, there is a free app called 'telnet lite' for ipad/iphone.
Could you install this and setup a connection for :-
Ip address 192.168.1.1
Port number 2000

When connected to the pilotaware wifi, run the connection defined above.
You will be prompted for a password, you can supply any 4 characters

The gps and traffic information is now streamed.
If we see a disconnect, then we know the issue is connectivity and unrelated to skydemon
I am confident that the issue is unrelated to skydemon, but would like this confirmed

Thx
Lee

Hi Lee,

The problem is random; sometime in 20' flight it happens 2-3 times, other in 2 hour flight nothing happens. I'll install the software and try tomorrow, I'll fly for 6-7 hours.

Many thanks for your support

P.S. If I connect SD to PAW using Wi-FI and FLARM protocol, I loose any internet data connection (before PAW I paired my IPad with my IPhone). Is there any way to have both?

I did some test to try to understand at what level the problem is (IPAs, SD e Classic).
When SD loose GPS signal the hotspot is on, so it seems no Wi-Fi dongle problem.
If I try to reconnect SD, some times it reconnect at the first temptative, others I have to try several times. So it's seems a GPS dongle trouble.
Ha e you any suggestions on how to solve the problems? It's boring to loose the GPS signal while flying

There are 2 messages produced by SkyDemon

1. lost connection to GPS
This is a WiFi connectivity / TCP Socket issue, and not an issue with the GPS device itself

2. searching for satellites
This is a GPS issue, because the GPS has not achieved a lock

an easy test, unplug the GPS from PilotAware and you will get message (2)

If your iPad is in range of 'known networks' it will drop and reconnect depending upon the strongest signal.
So if you are near your home wifi, you may se the ipad drop the connection to PilotAware, connect to Home, then reconnect to PilotAware

The only way to get around this, is to tell iPad to forget your home network, this will stop t connecting to other networks

I think the best solution between PilotAware and SD, is to use UDP rather than TCP, this is more tolerent to an individual lost packet.
TCP (in the SD implementation) just gives up and stops working.
I have been speaking to Tim at SkyDemon, and he is going to investigate using a UDP connection as a replacement to TCP

Thx
Lee

I receive the first kind of message. When I receive it, the Wi-Fi icon on IPad is on, full range.
I don't have in my plane any other Wi-Fi hotspot.
If I understand well, the only hope I have is to wait for SD will implement UDP instead of TCP (or TCP with re-connect option).

Thx

I too have the same problem. I run PAW with SD, with Anker power bank.
I run also an iPhone with Radar screen. When SD loose connection, the iPhone continue to run properly. Next flight I'll check if when SD loose the PAW connection, the wi-fi hotspot is on.
