[Microbit-Python] Repl not echoing back

[Carol Willing]

Hi Naomi,

Perhaps a shot in the dark, did you try picocom?  picocom /dev/ttyACM0 
-b 115200  Replacing with the correct port. I've used with the Mac Pro. 
I'm still running Yosemite. Are you on El Capitan?

You could try getting rid of any cruft of old USB /dev/tty files.


Damien, Does the microbit have a hard reset by pulling a GPIO pin low?
