My Nano33 BLE was working fine an hour ago. I uploaded a sketch to it yesterday. When I tried uploading a sketch to it again (an hour ago) it seemed to break. The computer could not discover the arduino in ports, i.e. when I tried plugging it into the computer and loading a sketch, it threw the following errors:
No device found on cu.usbmodem2301
Failed uploading: uploading error: exit status 1
I then plugged and unplugged everything, restarted the Arduino IDE and computer, etc. for a couple minutes - didn't work.
I then tried the iphone app that connected with it before problems started happening and the app would not connect.
The arduino usually advertises the name "Arduino". However, I can't find "Arduino" anymore when looking for advertising bluetooth devices.
I did have my arduino nano wired to another arduino. Perhaps I burned the nano when I plugged both arduinos into the computer at the same time. How would I troubleshoot that? The nano powers up (green light) when I plug it in (it just isn't discoverable when I plug it into the computer).
Any help would be greatly appreciated!
