Then I suggest you read back the flash data and compare it to the hex file you flashed to it. If they are the same then the program is intact.

Either way, you need to debug the program that's running on the dongle.

My setup is a peripheral (nRF52 DK) that sends extended adv messages (like "this is the <n> message"), a central that is connected to a windows laptop through USB, and a java program running on the laptop that reads messages from the serial port and print them to a console.

When the DK is being used as the central, everything works perfect.

However when we use the dongle as the central I see only "gibberish" messages which dont come from the board.

My only conclusion is that the code/hex wasn't really flushed correctly to the dongle.

We need details. What do you mean by 'see', and 'packets are not being received'. Are you relying on UART logs for your observations or are you catching the BLE events from the SoftDevice directly in a debugging environment?

I've changed the code to print only extended adv packets that are being sent from my nRF52 DK (programmed as peripheral) . When running the code on a 2nd nRF52 DK (programmed as central) I can see the packets, but when running the same code on the dongle, packets are not being received

What does not work? We can't help you if we don't know what the issue is.
