Greetings! I am trying to reflash an ESP8266 (via http://www.instructables.com/id/Turn-a-Cheap-WiFi-Plug-Into-an-OpenHAB-ESP8266-Swi/) but I seem to have lost my USB to TTL Serial Adapter.
I have an unused Particle Photon that I bought a few months ago for a different project.
Can the Photon be used to flash the firmware on the ESP? If so, any thoughts about how I might go about it? I’m really new about this stuff!
