Hi,

That is very strange. Could you save the file, and upload it here?

1) Do you see this issue multiple computers?

2) You have reproduced this on 1 DK and 1 dongle ?

3) What version of the DK is this? The version should be printed on a white sticker, below "PCA10040".

Hi Please check this screenshot. This is what it shows after device is reconnected. I programmed the DK with softdevice. Then i left it connected to PC. After some time the DK is reconnected by itself and auto play option appears again (the PC makes sound to show a new device connected). Then when i refresh the programmer in nRF connect and read. It shows empty devices. FYI, I read the DK after programming softdevice to see if it is programmed successfully or not. And it always a success.

Thank you.

You can check the flash content using e.g. nRF Connect for Desktop, and the programmer app.

Is this issue something you are seeing with several kits? Could you test with a different USB cable, USB hub, power it from a different computer, etc ?

I have not confirmed if its totally erased or not. But what i am sure about is that it does not work if i upload either the softdevice or the application. It only works when i upload both files again.
