I had an old version of ADSBExchange on my SD card. When I tried to update it, I always got error messages, so I got a new SD card and installed the latest image of ADSBexchange. Afterwards I must have re-entered all my old data via adsbexchange.local and also re-inserted the previously saved LONG-UUID (/boot/adsbx-uuid). However, I don’t know how to change the short UUID now. My Raspi now has a new SHORT-UUID. What do I have to do? Or is everything correct now? Björn ---

The short ID is a reduction of the full UUID. Are you sure that you used the same UUID? And reboot after putting it in place? And it’s really resulting in a different short ID?? ---

After I carried out an update via adsbexchange.local, I had my ShortUUID again. The restart would probably have sufficed. Thank you
