ESP8266 ESP-01 firmware update for Arduino via WiFi
We're creating a "transparent" UART bridge, which will allow
remote flashing of Arduino and other microcontrollers via Wi-Fi.
We're using the esp-link firmware.
Download the firmware and utility for flashing the esp-01 module here: https://yadi.sk/d/f843751fvsVEU
The archive also includes a diagram for connecting the esp-01 to a USB-UART converter.
