My apologies for the delay in responding, I am working from home during the lockdown and it took a while to get hold of some additional devices from our main stock to further the tests. Also, I realise now I hadn't noticed that I needed to tick the "Notify me when a reply is posted", so I did not know a reply was waiting.
I do also see this problem purely from the Phidgets Control Panel app. When I first start the program from fresh the device scans OK. After about an hour this becomes unavailable, although I still have control over both LEDs and the Digital Output. I have tried toggling the "AntennaEnabled" checkbox but it makes no difference.
I just created a log file - verbose so still rather large, and I attach it here. I actually saw the fault occur while I was typing this, the "RFID Reader/Writer" window closed and re-opened. The log file shows the problem occur at the very end of the file.
I do see the same error on multiple 1024s.
HOWEVER, I have since discovered that I am so far only seeing this on my one dedicated test laptop (a 2.5 year old Microsoft Surface Book 2 15"). I cannot replicate it on five other Windows 10 computers that I have tried it on (inc 3 laptops), so it seems to be an issue with the computer. I have checked all the hibernation and power settings and they are all disabled.
I also notice that the Phidgets Control Panel will not start at all once the reader has gone into this non-read mode, which is usually after an hour or so. There is no sign of a crashed version of the program in the Task Viewer. The only way to get it working again is to physically remove the USB cable and reattach it, at which point everything is reset.
I feel a lot easier that I can only see the fault happening on one computer so I am inclined to start rolling out a few units to beta testers for a wider sample, so I intend to leave it at this for now. The fact that your Control Panel app also has the same issue reassures me that there is nothing specifically wrong in my own code. If you do have any suggestions then I would be pleased to hear them, but hopefully this is a one off and I will hope to move on.
