ESP8266
I have already done upgrading firware but you don't need to. Simply use this library in Arduino IDE by following the simple provided instructions and you are good to use it like a regular arduino with WiFi onboard. The firware will be reprogrammed each time by the library.Any experiences about flashing fw?
My module came in but I'm too dump to solder the wires. So I've ordered a new one (ready soldered with pins)
