Projects using Pi 3

clem57

First usage of Pi 3

 

I installed the Piaware software to feed ADS-B into FlightAware. At first I had problem with Dongle in use:

 

Found 1 device(s):

0: Generic RTL2832U

  Using device 0: Generic RTL2832U

  Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.

  usb_claim_interface error -6
Failed to open rtlsdr device #0.

 

Luckily a solution is pretty straightforward. In /etc/modprobe.d create a file called blacklist.conf with the following:

 

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830

 

Apparently the upgrade incorporates a new Linux kernel which includes a DVB driver for the dongle as a TV receiver.  Since the device is already in use by this driver, usage fails by anything else. Next:

 

sudo reboot

 

Problem gone. Software works great on Pi 3.

 

Cheers,

Clem

  • The default driver for the DVB dongle is obviously the DVB one in almost all  the distros both for the RPI and for other devices so the possible/probable requirement to Blacklist or remove the DVB driver is a common one.

     

    You can have say one DVB dongle and another for SDR use by having both drivers but either forcing them to the correct devices via comman line options or UDev configurations based on say the device S/N rather than just the USB  ID

    Maybe I might need to try the FlightRadar24 software and see if it has any issues.

    I think I have a compatible dongle sitting around, but not sure if it has an external aerial.

  • The fun never ends. Last night the power goes out and stops PiAware on the Pi 3 of course. When power comes up, The pi 3 beat my router and the time was set by NTP 41 minutes late. So need to do either:

    sudo service ntp restart

    sudo reboot

     

    Next I change my password and needed:

    sudo piaware-config -user username -password

    The password will be prompted for.

    Weird thing was a sudo /etc/init.d/piaware start did not work. Finally a sudo reboot did.

    Lastly a look at the log in /tmp/piaware.out shows connection or enter:

    sudo piaware-status

  • I have been up for over 1 week and have published data for http://flightaware.com with the following statistics:

         Date joined                    Days          Tot flights    Ave/day   Tot pos     Ave/day        Tot flights     Ave/day     Tot pos     Ave/day 

                                                           ADS-B =============================>     MLAT==============================>

     

    ADS-B     is planes sending information

    MLAT     is signals triangulated for position information

  • A check on Piaware:

    pi@raspberrypi:~ $ sudo piaware-status

    dump1090 is running.

    faup1090 is running.

    piaware is running.

    dump1090 is listening for connections on port 30005.

    faup1090 is connected to port 30005.

    piaware is connected to FlightAware.

    dump1090 is producing data on port 30005.

    Computer is working! Processor is running at around 6-10%
