    How-to Feed Plane Plotter Site directly from Raspberry Pi

    This method is applicable to:

    • PI24 image
    • Raspbian image with dump1090-mutability ver 1.15~dev
    • Raspbian image with dump1090-fa
    • Piaware SD Card image


    CREDITS:

    http://www.satsignal.eu/raspberry-pi/dump1090.html

    STEP-BY-STEP METHOD

    NOTE:
    The PI24 image sometimes refuses to install packages, or save edited files, and gives following error:

    "read-only file system"


    This problem is often solved by rebooting the Pi.
    Code:
    sudo reboot
    If rebooting does not solve the problem, then give following command
    Code:
    sudo mount -o remount,rw /
    (1) Install packages necessary to build and necessary to fulfil dependencies.

    Code:
    sudo apt-get update
    sudo apt-get install git
    sudo apt-get install librtlsdr-dev
    
    sudo apt-get install cmake
    sudo apt-get install libusb-1.0-0-dev 
    sudo apt-get install pkg-config

    (2) Build the Planeplotter uploader `ppup1090` from source code of dump1090 (Malcolm Robb)

    2.1 - Clone/download the dump1090 source code from Github.

    Code:
    cd ~
    git clone git://github.com/MalcolmRobb/dump1090.git
    2.2 - The downloaded directory's name is `dump1090`. To make it clear that this is not dump1090 mut or fa, but is PlanePlotter Uploader, change it's name to "ppup"

    Code:
    sudo mv dump1090 ppup
    2.3 - Enter folder ppup

    Code:
    cd ppup
    2.4 - Obtain Planeplotter Configuration/user key
    Go to http://www.coaa.co.uk/rpi-request.htm and enter your details, and your co-ordinates. You will then be e-mailed your own personal copy of a file called `coaa.h`.

    2.5 - Add Planeplotter Configuration/user key
    In directory `ppup`, you will find dummy file `coaa.h`. Replace it with the `coaa.h` you have received by email. Use any one of following 2 options.

    Option-1:
    Use FileZilla or WinSCP or similar program to copy file `coaa.h` from your Desktop/Laptop to RPi in folder `ppup`.

    The file `coaa.h` cannot be directly copied to folder `ppup` due to permissions problem. To overcome this problem, copy it to folder `/home/pi` which has permission for copying files using SCP or FTP.

    Once you have a copy of file `coaa.h` in folder `home/pi`, SSH to Pi, and issue following command to copy it to folder `ppup`:

    Code:
    cd ~/
    sudo cp coaa.h  ppup/

    Option-2:
    Open file coaa.h received by email using MS Word or Wordpad
    It's content will be like this:

    Code:
    //coaa.h configuration file for ab cd 2018-07-11 05:58:29
    #define USER_REGNO xxxxxxx
    #define USER_AUTHCODE xxxxxxxxxx
    #define USER_LATITUDE xx.xxx
    #define USER_LONGITUDE xx.xxx
    open file coaa.h in RPi's folder ppup for editing
    Code:
    cd ~/ppup
    sudo nano coaa.h
    following will be displayed
    Code:
    // coaa.h configuration file for Plane Plotter Uploader
    //
    // You MUST apply via the COAA website for your own personal version of this fi$
    // Do not disclose the contents of this file to anyone thereafter as it uniquely
    // identifies you to the PlanePlotter system
    //
    Press (Ctrl+k) to delete all these lines and make this file empty.
    Copy-Paste all lines from the file coaa.h which you received by email) in the file coaa.h in RPi.
    After pasting, it will become like this

    Code:
    //coaa.h configuration file for ab cd 2018-07-11 05:58:29
    #define USER_REGNO xxxxxx
    #define USER_AUTHCODE xxxxxxxxx
    #define USER_LATITUDE xx.xxx
    #define USER_LONGITUDE xx.xxx
    Save (Ctrl+o) and close (Ctrl+x)

    2.6 - Compile the ppup1090 (plane plotter uploader) from source code

    NOTE: Only the "ppup1090" component of cloned source code needs to be compiled for uploading to Planeplotter. You don't have to compile dump1090 itself because:
    - In PI24 image dump1090-mutability is pre installed.
    - In Raspbian image, you have already installed dump1090-mutability ver 1.15~dev or dump1090-fa.
    - In Piaware SD card image, dump1090-fa is pre installed.


    Code:
    cd ~/ppup
    make -f makeppup1090
    2.7 - For Pi24 IMAGE ONLY
    Open browser and go to settings page:

    IP-OF-PI:8754/settings.html

    In this page in field "Process Arguments" add following, if already not there:
    Code:
     --net 
    Click Save button, then Restart button. Both these buttons are at bottom-right corner of settings page.

    2.8 - TEST

    Code:
    cd ~/ppup
    ./ppup1090
    The above command generates following output if installation is working OK.

    (3) Make ppup1090 to auto-start at boot

    3.1 - Create a blank file ppup-maint.sh

    Code:
    cd ppup
    sudo touch ppup-maint.sh
    sudo chmod +x ppup-maint.sh
    sudo nano ppup-maint.sh
    3.2 - Copy-paste this code
    Then Save (Ctrl+o) and Close (Ctrl+x)

    Code:
    #! /bin/sh
    while true
      do
        sleep 30
        /home/pi/ppup/./ppup1090  > /tmp/ppup.log 2>&1
      done
    NOTE:
    The log file /tmp/ppup.log grows in size very fast.
    After initial testing, you should stop logging by deleting above code from file ppup-maint.sh, and in it's place copy-pasting following code

    Code:
    ! /bin/sh
    while true
      do
        sleep 30
        /home/pi/ppup/./ppup1090  --quiet
      done
    Save (Ctrl+o) and Close (Ctrl+x)

    3.3 - Open file rc.local to edit
    Code:
    sudo nano /etc/rc.local
    In the file opened, copy-paste following line just above last line (i.e. above exit 0 )

    Code:
    /home/pi/ppup/ppup-maint.sh &
    Save (Ctrl+o) and Close (Ctrl+x)

    Now Reboot to start the system
    Code:
    sudo reboot
    (4) CHECKS

    4.1 - Check log
    Code:
    cat /tmp/ppup.log

    ppup-log.png


    4.2 - Check ppup1090 is running
    Code:
    top
