Flew with the N7 and the PAW yesterday and it was a non-starter, the unit  constantly disconnecting every minute, with messages in Skydemon saying Lost GPS connection or lost connection to the butterfly. It was also a pain to get the initial WIFI  connection to the PAW from the N7.

I also tried from my phone (cheap Chinese Android clone) and this was stable, connected easily and Skydemon worked well.

Thanks for the excellent clarification Peter, I obviously thought the Zaon was cleverer than it was, using timings between Radar interrogations and A/C replies to triangulate distances, clearly it 'cheats'!

Still. when every flying machine is fitted with a PilotAware with ARF (and who shouldn't at this cost) We won't need to worry!

Thanks Peter.

Can't say I'm particularly interested in the audio warnings but can you describe the specifics of the 'Mode S' detection as against the ADSB? does this provide the PCAS type functionality?

General Discussion / Question about PilotAware Bridge

« on: May 26, 2016, 07:32:12 am »

I first became aware of PAW a couple of weeks ago when I repaired a friends Zaon PCAS antenna, and , having the opportunity to fly with it , liked the Idea and scoured the net for a possible home built solution, initially seeing Lee's post on the Flyer forums asking about such a possibility. I then had the amazing opportunity to read the full development of the PAW in a few hours! 

I assembled my PAW from parts I had around and a few other items sourced on Ebay (stupidly only a Pi B+) in around an hour. All up and working first time seeing ADSB replies which is a great credit to all those who have worked so hard over the years.

I am going to buy the Radio bridge for my home built setup when it becomes freely available.

Does it come with the antenna and spacers etc to mount it on the Pi? there is no mention of these parts on the hardware site.

Maybe I missed it but I can't seem to see it anywhere.

Thanks

Hi Paul, yes I initially achieved a connection from around 2 metres.

From the front bedroom of my house (in Essex) with the PAW unit sitting on the windowsill, SD was showing ADSB targets as far away as over Manston at FL300, some 40NM away..

I moved the PAW to the back bedroom to get a better line of sight to the West but kept the Nexus 7 in the other room, the two were around 20 ft apart and separated by a stud wall but remained reliably connected. 

It's achieving the initial connection that I am still having problems with there's definatel;y something quirky with the wifi in the N7, Google has made several fixes to this over the course of Android builds for this machine.

I am using a Cyanogenmod ROM on my N7 based on KitKat to acheive something near a usable speed (though SD, once loaded runs perfectly)

Hi All

It was my first running attempt of anything to do with PAW yesterday having just received a wireless adaptor. I too was using a Nexus 7 2012 and was experiencing the same issues as Paul. When looking at the list of available wireless stations prior to attempting the connect, the Pilotaware WAP kept appearing (with good power) then disappearing completely for a second or two. On an unsuccessful attempt to connect, it wouldn't even attempt again until I 'forgot' the PAW and re tried to connect (though still unsuccessfully).

I used 'WiFi Analyser' app on my phone to have a look at what was going on in the spectrum and it showed the PAW on channel 9, the highest signal on the screen but occasionally dropping away to nothing. Significantly,my home access point is on channel 10. I switched off my home wifi briefly and managed to get the N7 connected and it stayed connected even with the home WiFi back up.

I was wondering if the dropping of the PAW signal was some form of auto channel selection trying to kick in but being prevented by the PAW software until something manages to connect to it?

This is , of course, all probably not too important in 'real world' flying use as the PAW is most likely to be the only WAP inside the aircraft
