Title: wifi problems
Post by: Annep on September 25, 2015, 10:03:35 am
Problems since I changed to the latest release software. Before this it has been working fine.
Now I see pilotaware on the wifi list and after I choose it  the ipad ticks to imply that it's connected but I don't get a wifi symbol on the top left and collision aware won't connect.

I've tried going back to the  previous release but I still have this problem. I'm not sure what I've changed during this process....... I'd be grateful for any suggestions

thanks Anne

Just to clarify, you are running 20150919 ?
If you successfully connect to the WiFi
can you point your Safari Browser to
http://191.168.1.1

Please take a screen capture and post here - this should give some info about your system

Yes running 20150919
However flown today from Scarborough to East Fortune and it's working, just that wifi symbol not there.  The only problem we had was with loss of connection about 3 h in just before arriving at East Fortune. Before that seemed to be fine, picking up quite a few targets.

Can you clarify exactly what is meant by

I have changed the settings of PilotAware, so you can continue to use the 3G for internet whilst connected to PilotAware, this is a deliberate change.
So it this what you are referring to ?

AIUI the WiFi 'fan' symbol on the status line only appears on WiFi if there is an 'internet' connection. It doesn't signify a WiFi connection, which is a bit misleading.

I still get connected ok but still keeps dropping out. latest  update itunes. 
once Wi-Fi  connection drops off it doesnt reconnect until you reboot.
Any reason it keeps dropping off Lee?

I think we need to investigate a bit further.
Please be specific when you say 'dropping out' because we have a pretty complex setup where
we have
- WiFi Connection to PA
- CollisionAware Socket Connection
- NAV S/W Socket Connection

So I think you are saying you get an initial WiFi connection, this then disappears - and does not reappear
is that correct ?

I have asuspicion that some WiFi dongles are either
1. Hitting the default RPi power limit of 600mA for USB
2. Going into power saving mode.

Hello,

I received a new Raspberry Pi and the wifi is connecting flawlessly with that new board.
The two Pi's look almost exactly the same but further investigation showed that the first board is marked : Raspberry Pi 2 model B V 1.1 as the other is marked  Raspberry Pi 2 model B+ version 1.2.
I thought Pi2's were all the same and there was only a difference in PI1 between B and B+.

I'll ask for the licence in the correct thread.

Hmmm, I'm confused  :o
As far I am aware the following Raspberry Pi's are in existance

Pi 1 A+
Pi 1 B+
Pi 2 B

https://en.wikipedia.org/wiki/Raspberry_Pi

PilotAware is only intrended to run on Pi B+ (meaning version 1 B+)

Thx

Licence installed , WIFI connected, traffic seen in Skydemon.

Well the board is printed with that information : Raspberry Pi 2 Model B V 1.1 and it is not working.
I bought it on Ebay from some seller in China it could be fake or low quality!!!

Can we clarify the connection that is being lost ?
    Skydemon/Butterfly connect ?
    WiFi Connection ?

I think in nearly all cases I have seen it is due to 3 possible issues

1. Power Supply
2. USB Power Cable
3. WiFi Dongle

The power supply is especially put under pressurw when the ARF starts transmitting.

You also mention 'updated software', it is always best to refer to a release so that I know what is being referred to

After having a working pilotaware for a couple of weeks I'm now really struggling. I updated the software and was, for a time confused, by the absence of the wifi symbol, but the system was working and I understand this is now just that you have changed things to allow the phone network to operate at the same time?

then I became unable to connect to the wifi. Pilotaware just wasn't showing on the ipad, so I thought perhaps the wifi dongle had failed, so..... I have purchased a ralink rt5370 chip wifi dongle which shows, but not as pilot aware. So I purchased another wifi dongle which shows as pilot aware but with a different end number to the original dongle, but when I try to go to 192.168.1.1, it goes to a google search page, if I disable the phone network then it just says unable to connect.

Please can anyone help?

thanks Anne

Hi Lee
Yes it says     Skydemon/Butterfly connect ?
using version 0926 but see you have released another update. of which i will try
Power supply is 12v to usb built in.
Wi-Fi dongle swapped for another same outcome.

I will try a USB power monkey back up to see if this helps.

Many thanks. Glenn

Hi Anne

I think you have already discovered that the WiFi symbol is irrelevent as far as PAW is concerned, so no need to worry on that issue

Please can you explain this statement

what do you mean it 'shows', shows as what? and where ?

The name of the Hotspot is derived from the unique identifier in the WiFi dongle

So just to confirm, on your iPad you see a new WiFi Hotspot appear, you connect to the Hotspot, then you point safari to
http://192.168.1.1
but this fails ?

Are you running CollisionAware, or a GPS dongle connected to PilotAware ?

with the first wifi dongle which is a ralink 5370 when I power up the raspberry pi the ipad shows a new wifi network it calls TNCAP55DC21

The second dongle shows pilotaware but will not connect to the 192.168.1.1 when I try to open with Safari

Can you boot with a monitor attached to see what the boot messages are
Also can you tell me where you purchased the wifi dongles, I am trying to keep a list of known good vendors

HI Lee

We're getting a recurring message that says License Fail for Host 7C:DD:90:9D:3A:D5

wifi dongles are from amazon, the one that doesn't work at all is https://www.amazon.co.uk/gp/product/B00UFJ0MI6/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1

and the one that shows pilot aware but won't open 192.168.1.1 on safari is https://www.amazon.co.uk/gp/product/B00EK3U2FQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Hi Anne
Not sure if this is related, but I have read some postings which say some wifi dongles only work when they are in the usb slot furthest from the rj45 ethernet connection, sounds like a long shot to me.

It seems there are a lot of wifi dongles which really are not compatible.
 
There is a known good list here posted by members
http://forum.pilotaware.com/index.php/topic,110.0.html

I may have asked before, so just wanted to confirm the power supply and power usb cable you are using ?

Thx

At the moment (at home) I'm using the mains plug supplied with the raspberry pi.

Once it's working  again I've an Anker 20000mAh power pack with a 20 awg sub cable

Hi Lee
Iam using collisionaware app

did a test at home this is what happened?   
working ok, then after a bout 1/2 hr had this
The exact words are

''The connection to your GPS has been lost''

click ok it says

''Please wait while a connection is established to your external device''.

then it says

''Failed to establish a connection with the Butterfly connect unit''

software 1003
Collisionaware App latest version 0.3
USB power mains

Any idea? as this seems to be the only fault i have otherwise perfect


Title: Re: wifi problems
Post by: Admin on October 08, 2015, 10:48:41 am
Hi

Can you tell me what is in your system, do you have the ARF available ?

These issues tend to come down to 3 issues, in this order

1. Quality of USB Power supply & cable
What is the current output of your power supply
What is the power rating of the cable eg 20 AWG ?

2. WiFi Dongle
Should be RT5370, but many (alleged) RT5370 have issues

3. WiFi interference

Thx
Lee

Hi Lee
by gad mate i think ive cracked it. 
You sent me a WI-FI dongle which i kept in case mine was crap, guess what after 10 minute i kept losing
connection so change everything in sequence it appears it be the wi-fi dongle bought from
ebay.
http://www.ebay.co.uk/itm/231483794170?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

this doesn't say on the packet what the chip set is, it's just advertised as the RT5370 but it defiantly is the reason.
Can you post me a link where you purchased yours from?

Many thanks Glenn

So Lee can i asked where you got yours  from?

Title: Re: wifi problems
Post by: wyrleybird on October 12, 2015, 03:38:35 pm
Lee tried it again today on the wi-fi dongle  that was dropping out and its seems ok, been on for 1 hr so don't know whats going on.
Update   there seams to be differences in the wi-fi dongles with the same chipsets but the one Lee sent me never drops out.
the one on ebay advertises the correct chipset but doesn't say in on the packet.

I am also having problems with Wifi dropping out.  Sometimes all is ok for an hour, sometimes it drops out after 10 minutes. I get the message "lost connection" and "failed to establish connection with Butterfly Connect unit".

I am using all the components from the hardware list including a 20 gauge USB power cable.  The wifi dongle is in the slot furthest from ethernet port and is blinking away happily. The dongle is this one:   http://www.ebay.co.uk/itm/231483794170?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

I have SD running on an ipad mini with collisionaware and GPS info being supplied by an external GPS ( XGPS160 via bluetooth). The power supply is a fully charged portapow 10200mAh battery. Their blurb says it can run raspberry pi, along with all the usual other things. I have also had wifi drop out when being powered by an ipad charger plugged into the mains.

Any ideas - bad wifi dongle? collisonaware?

Title: Re: wifi problems
Post by: Admin on October 21, 2015, 07:38:20 pm
Hi James

One common thread seems to be emerging, and that is external bluetooth gps.

I am wondering if the ipad does not have the power to maintain 3 simultaneous connections.
Effectively, you have
BT - iPad
Skydemon - PAW
CollisionAware - PAW

This is the one common factor I see.
By any chance do you have a USB-GPS you could connect to PAW ?
If this were to stay up, it could be an indication of what I am saying

Also what versions of PilotAware and CollisionAware are you using ?

A final alternative would be to use nmeagps instead of collisionaware

Thx
Lee

Hi Lee,

I am using pilotaware version 20151003. I downloaded collisionaware last week - is there a new version of this?

Don't have a GPS dongle to try but can give it ago some time soon.

I was hoping to keep on using my external GPS because it has proved to be reliable, it does glonass and GPS and can bluetooth to more than one tablet at a time.

Does £150 of GPS buy any better reliability than a £10 dongle?

Having said all that, SD and pilotaware have been running for the last 2 hours without any dropping out!

My setup is an old iPad 2 with IOS 7.1.2 and Sky Demon, CollisionAware, and an external Bluetooth GPS - the GNS 1000.  The connection is solid and reliable...... but my longest test is just over an hour.

Post by: Paul_Sengupta on October 21, 2015, 10:35:18 pm
Aha! I had this "wifi drop out" last night with a specific setup so I decided to investigate this evening.

In my attic, I have a DVB dongle connected straight into a coaxial collinear antenna, and thence to a 5m USB lead. It works great with my PC.

I received my Pi B+ through the post yesterday to replace my existing B, to make a proper unit which can take a USB GPS as well (on order). I was trying out the B+ with one DVB dongle and it was working fine here in the house. However, by the time I got it working it was late at night and there weren't many airliners around. So, thought I, I would go upstairs and plug my antenna/dongle/5m USB lead combo into the Pi to see if I could get any aircraft from further afield.

So what happened? Well, the Wifi wouldn't stay on, it kept dropping out and wouldn't connect back unless I rebooted the Pi. It stayed on from a matter of seconds to a matter of minutes, but drop out it did. I tried it with two different tablets. So then I went to bed...

This evening I had another go, and sure enough, same results. When I swapped the DVB dongle back to the one I was using before, plugged directly into the PI, the Wifi stayed up...and it's running up in my bedroom now and has been up for hours.

So it could be the DVB dongle, or the combination of stuff plugged into the USB ports may be overloading the power available on the sockets.

I meant to try using my Pi B instead of the B+ but I haven't got round to it yet.

I have done several tests with 2 sets of hardware except the pi     I now have a fully working PilotAware which never drops out.
I went flying for 3 hr still all ok, tested at home for 9hrs still no drop out.
The problem i had was the wi-fi dongle, the other one was ok but kept dropping out randomly,  the one I had off Lee of which was slightly shorter
on the head never dropped out.
So Lee where did you get that one you sent me?
Oh by the way the one that drops out is from Ebay known good sources.
