Reply To: pc and Mac unable to communicate with mayfly ver. 0.5b

I’m using Arduino 1.8.19.

I’ve tried uploading a sketch (various ones) and get a not in sync error message that repeats 10x.  Entire error message below…

Now don’t kick me, but I don’t know what “looking at it through a serial monitor” means.  I do have it set to 57600 baud.

the port reads as follows (on my MacBook) port:”/dev/cu.Bluetooth-incoming-Port”. serial port above that is greyed out.  I don’t see any usb options.

thanks so much for your help and guidance!
