Hi, 
I have an Arduino BLE33 Sense but there seems to have an issue.
Currently it is blinking the orange LED in a pattern like SOS Mors [... -- ...]  ( this is not in any of my sketches ) and I was thinking if that is any alert code?
I cannot seem to find any serial port to upload a new sketch....
Anyway, I tried to do the double reset the LED is pulsing but again no serial port anywhere...
I cannot understand if it is a FW issue or a HW issue but it is not usable. Any suggestions?

I was working perfectly with this device, decided to change a parameter value - in a commented out region -  and then the crush. I recall it finished properly the uploading and I am 101% sure it was not the source code that caused the issue.

Any help will be highly appreciated.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
