Binary to update ESP8266 firmware to Espressif firmware. Requires user to press buttons.

Dependencies:   BufferedSerial mbed

Fork of ESPQuickFlash by Christopher Haster

How to Use

This program will update the firmware on a connected ESP8266 to the Espressif Firmware. The user will need to put the ESP8266 board into FW Update mode and follow instructions as given on the serial console.

Between each block transfer power cycle the ESP8266 and put back into FW Update mode. On the Seeed Grove Serial WiFi module this requires a short press followed by a long press on the esp8266 reset button untill the light on the module goes red.

Terminal Settings
