How do we manage to adopt your trick Lee
  " very neat trick where I boot the disk in a read only mode"
Please??

Sorry, I did not explain well enough.
The PilotAware software installation does this automatically.
So pulling the power should not be an issue.

I was trying to explain that in a normal Raspberry Pi installation, such as installing NOOBS, you should
not simply pull the power, because this will cause the SD card to no longer reboot.

For PilotAware - no such worries

if you run under simulate, this gives a better idea what it will look like

Perfectly articulated Kev, this is exactly the problem

Usually a raspberry pi must be halted before removing the power, or the disk can be trashed.
I use a very neat trick where I boot the disk in a readonly mode, this makes it tolerant to removing the power without halting.
There is the odd occasion when the disk is in a writable mode, for instance when you enter the license key. At some point in the future, it is likely that updates will be done whilst the system is running, and hence similar care will need to be taken

General Discussion / Re: USB - RS232

« on: September 13, 2015, 01:30:27 pm »

Hmm, lots of questions here

A) This is to provide GPS info into your mode S transponder so it can transmit position info. We have a funkwerk mode S transponder which I think may work with this so is interesting.

Can you tell me what you are referring to ?
I think you may be talking about the early work I did to get an RS232 stream of NMEA sentences out
of PilotAware ?
If so, I prototyped this a while back, and managed to feed a stream of NMEA sentences to the RS232 port on my PC
This could be connected to a Mode S Transponder if desired.
Some configuration setup needs to be done, some transponders use different baud rates.

B) It's not currently legal to connect this (this is what the NATS ADS-B trial is doing)

I hear that this ruling is to be relaxed very shortly

C) Without this, only other PilotAware devices will see position info for you.

Correct, as received on the P3I RF

Also, this is where the model B (rather than B+) stops working as a solution as 3 (or 4 with the GPS dongle) USB ports are required.

This does confuse me, I am using a Pi B+, this works fine, are you thinking that a Pi B+ does not work with PilotAware ?

The issue with PilotAware, is that it does not yet work with the Pi 2

General Discussion / USB-GPS Working in PilotAware

« on: September 13, 2015, 12:47:54 pm »

Hi All

Just finished testing the integration of the UBlox-7 USB-GPS, one of these
http://www.ebay.co.uk/itm/USB-GPS-Receiver-VK-172-Ublox7-Fast-10Hz-GPS-Glonass-RasPi-Win-7-8-CE-Linux-/252080341676?hash=item3ab128c2ac

And it works nicely.
This means I am now running the NAV software on my WiFi Ipad, position info and traffic info supplied by PilotAware, from the USB-GPS

At the moment this is hardwired to use a specific USB port on PilotAware

Thx
Lee

Do you have a monitor connected to the HDMI port, are any messages reported ?

Hi Stephen

I followed up with this patched version
http://forum.pilotaware.com/index.php/topic,48.msg675.html#msg675

I have had mine running for hours
Is it always 20 mins ?
Thx

Sd has traffic filters, have you altered to pick up high traffic ?

Does the addition of support for the NMEA app remove the need for CollisonAware? I think I remember this being discussed.

Currently I still need a GPS sharing App, so you can use CollisionAware, or GPS/NMEA.
The purpose of putting in the NMEA parser was a halfway house to incorporating a GPS directly
without the need of having GPS in the iPad/aPad

I recall you have another requirement as part of paramotoring, or is my recollection wrong ?

Thx

Can you see the WiFi ?
Can you connect to the Wifi, if so browse to http://192.168.1.1

Success!! I think

After looking at the raspberry pi forums I have copied the config.txt file from my 'good' card onto my pilotaware card and that seems to have done the trick. Just waiting for it to install now.

thanks for your help and apologies for not reading your instructions better.

Anne

Can you paste the contents of your config.txt file in case others have a similar issue.
I am guessing it is something related to the monitor ?

Thx

I have no idea, I have just downloaded the image, and tried here.
Is now installing ...

This sounds like a general PI issue, rather than PilotAware.

Don't know whatto suggest to be honest.
Did you format the disk before loading the data,
and did the disk appear to have all the space that it should, ie 4GB ?

General Discussion / Re: CollisionAware Dropout / Disconnect

« on: September 12, 2015, 02:14:27 pm »

I am trying some experiments

1. Increasing power of RPi WiFi output to 50mW
this was previously set to 5mW, I will look to make this
configurable through the web interface at some point

2. decreasing wireless speed from mode g to mode b
mode g is 54MBit/s and mode b is 11MBit/s
I would hope that the lower the data rate the less likely
a dropout occurs, and 11MBit/s is still way overkill for the
data rate we require.

so expect a patch upload shortly after I have ran mine
for a few hours
