  • Configuration issue: Question 4.3 (COM Port Number/device path)

    Hello,

    Very sorry if this has already been covered here, but I've not been able to find it. Please help!

    I have a Raspberry Pi 3B+ running the Pi24 image. Hardware is a NooElec NESDR Mini USB RTL-SDR & ADS-B receiver. The receiver hardware seems to be working fine - as if I run /usr/bin/dump1090-mutability, I get a rapid stream of data. My problem is that I cannot work out what to put in for Question 4.3 - i.e. my port/COM number.

    The command lsusb gives this:

    Bus 001 Device 004: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T

    From dmesg, I know that my hardware is detected. I see a troubling message about the instance being deinitialized and disconnected, but as my data is coming through I have assumed this can be ignored.

    I don't have any /dev/ttyUSB ports.

    I have tried putting in /dev/bus/usb/001/004 (from above), as well as /usr/bin/dump1090-mutability, and have also tried various network options. None of them seem to work and I'm at a loss. Here's a typical message from /var/log/fr24feed/fr24feed.log

    Can somebody help?

    Many thanks,

    Martin

    If its the image, dont touch the config

    The dvbt setting is automatic

    Changing it when you dont know the implications can make matters worse.

    You appear to have changed it already to microadsb.

    You dont have one of those.

      Thanks for replying. I went for the manual config as the FR24 website didn't pick up my Pi. Can you advise on what I shoudl be putting if I don't have a microadsb?

        Microadsb is a different device with different hardware marketed as that.

        You have a tv tuner. Dvbt (digital video broadcast tuner)

        The pi image starts and feeds automatically. However now the config has been changed this wont happen.

        ​​​​​​​Either change to 'dvbt' again, or setup dump1090 separate and use beast-tcp:30005 - wiedhopfs github script can help there.

            Go with the bundle, it provides an interface that isn't FA branded: https://github.com/wiedehopf/adsb-sc...for-dump1090fa

            Anyhow the above link will also fix up your configuration.
