2019 connect old esp8266 Huzzah
- Connect to usb using FDDI 3.3v cable (White usb plug)
Connect to serial /dev/ttyUSB using screen
sudo screen /dev/ttyUSB0
When i click the reset button on esp8266 i get the welcome message
NodeMCU 0.9.5 build 20150318 powered by Lua 5.1.4 lua: cannot open init.lua
Switch on red led on esp8266 using lua commands
gpio.mode(3, gpio.OUTPUT) gpio.write(3, gpio.LOW) #Pause red led on gpio.write(3, gpio.HIGH)
Program the HUZZAH ESP8266
For the HUZZAH ESP8266 breakout buttons for GPIO0 and RESET are built in to the board. Hold GPIO0 down, then press and release RESET (while still holding GPIO0), and finally release GPIO0.
$ sudo esptool --port /dev/ttyUSB0 erase_flash
