Nano33BLE stuck / port not working / double reset neither

Hardware Nano Family Nano 33 BLE

Hi guys,

My Nano33BLE is stuck. The double reset doesn't work, the port is not recognized by windows 10.
Note: I have another Namo33BLE that works like a charm.

The NINA-B306 Module Bluetooth chipset, at the end of the board, gets really hot.

I saw in the forum that I'm not alone with this issue. Can someone help please?

When I plug the USB the green led glows and a couple seconds later the orange led is blinking at a steady 4 Hz.

Thank you very much,
Paul

If the double reset does not get you to the pulsing led and program mode then the bootloader may have been corrupted. Here's a link to a thread which addresses this issue.

Thanks cattledog, I will try to program the bootlodder with a spare Arduino and the Adafruit_DAP code.
