I tried to use IR LED on ESP8266 but it didn't support 38k frequency, so I have to use Arduino to drive an IR LED. It will receive data from ESP8266 through soft serial, but for some reason, I want to transmit hex data to Arduino to flash it. Is anybody know how to do this?
I know the AT firmware can set transmit transparency mode to do this, but I want to know how to flash it using Espruino, thank you.
