How-to Serialize Dongles for ES1090 + UAT978

I think you’re right. See below. Thank you for your tips and help with this!

System ran fine most of the day. Noticed that it lost 1090 late afternoon approx 21:21 logtime. Didn’t have a chance to look at it until this evening and 1090 was back up.

I noticed the following. Could this be caused by a inadequate power supply? current one is 5V not 5.2. Have a original raspberry 5.2V arriving Thursday.

Yes, the hardware is very unhappy there.

Im trying to upgrade the serial number on my orange flightaware stick but seeing some odd behaviour. Ive tried on two machines and see the same error on both.

Any idea what I need to do to be able to update the serial number from the crazy 16 digit one?

Try with only a single dongle connected and see if anything changes?

Once I had some difficulty changing Serial # of one of my ProSticks. I used the Windows software “RTLTool” with success. Use it carefully, see note below.

Go to
https://www.sdr-radio.com/Radios/RTLDongles

Scroll down to “The Files”, under which you will find “hosted on Google Drive Link” where the files are hosted. One of the files on Google Drive is “RTLTool”. Download it.

This software is portable i.e. does not require installation, and runs directly when RTLTool.exe is double-clicked.

IMPORTANT NOTE:
This tool can modify many parameters. Take care while using it that you do NOT modify anything other than the Serial Number. Modifying other parameters, without fully understanding what are you doing, may result in bricking your Dongle.

I actually tried with only a single stick first, on both machines, and got the same results.

That SN seems unique enough.

Why not just use it? Or does it change when you take it out and plug it in again?

@obj
@UcGytY223PdAy36f
I also faced exactly same problem, and later fixed it by Windows software “RTLTool”

Please also see item 3.8 & 3.9 of the post quoted below. It gives problem, but not the solution, as I found the solution later:

the number is unique in my infrastructure but that number does appear to be a generic serial number. I haven’t been able to get my dump978 working yet to verify if it connects to the correct stick though.

Is this a good test or is there something wrong. I’m not getting feed from 978 mhz.

Just means that most likely the dongle is already used by one of the dump programs.
