Hi,

Is the FlightAware USB stick supported in this container?

Thanks for your work !

Regards

Yes it certainly should be! Are you having an issue with it?

Yes I have two sticks on the device and I only want to use one stick, because the other one is in use for HAB.

I tried with this setting but it does not work: --device /dev/bus/usb/001/003:/dev/bus/usb/001/003 \ also not with --device /dev/bus/usb/001/003:/dev/bus/usb so a bit desperate now :-)

Better to set a serial number for the SDRs, which can be done with rtl_eeprom -s <serial>. Here's what I'd do:

  • disconnect the FA stick
  • run rtl_test- this will display the serial of the device you're using with HAB, and probably an error because that SDR is in use—ignore it.
  • connect the FA stick
  • run rtl_test again, verify the FA stick is now displayed—it will be the one with the different serial number from that you noted in previous step. Take note of the device number, which will be 0 or 1.
  • run rtl_eeprom -d <device number> -s <serial number to set>, confirm the change.
  • Unplug the FA stick, and plug it back in.
  • run rtl_test again to verify the new serial shows up.

Note that just because you're plugging in a new SDR doesn't mean it will get the next sequential device number, so don't just assume the FA stick will be 1 when you plug it in.

The serial number can be alphanumeric and up to, I think, 8 characters. I would suggest 1090 if you're doing ADSB.

So for example, rtl_eeprom -d 1 -s 1098 would be the command.

Like @dziban303 said, except make the serial number 8 digits in length, ie:

If you wanted to give the device an 8 digit serial number of 87654321:

rtl_eeprom -d 1 -s 87654321

or what I prefer is to use zero padding on a smaller number like so:

rtl_eeprom -d 1 -s 00001090

It doesn't need to be exactly 8 characters. In my feeder systems I use 1090, 978, 130, 136, & 162. Zero-padding unnecessarily complicates things, IMO.

It works !! Great, thanks guys !
