Put your Photon in DFU Mode (Device Firmware Upgrade):
a.) Hold down BOTH buttons (reset and setup);
b.) Release only the reset button, while holding down the setup button;
c.) Wait for the LED to start flashing magenta, then yellow;
d.) Release the setup button; the device is now in DFU Mode (yellow blinking led);
Start your Particle CLI via terminal with the command
Interesting… How’s this all working? I want to learn Python AND I have a little home automation project that I want to tackle.
