I was going along great loading Otto Blocky Examples and running the code. Today something changed. When I try to upload anything I get the following error: ser_open(): can't open device "/dev/tty.usbserial-1140": Resource busy error during upload. The last upload that worked was the App code that enables a bluetooth connection to the Otto app, and that still works. Any suggestions?
