Next, install using the Arduino Boards Manager. This will require Arduino version 1.6.8 or later.ĭownload the ESP8266 Arduino repository here:

Start by installing the necessary packages to program the ESP8266 directly from the Arduino IDE. It takes a couple of steps to install, but the steps are dead simple. Installing the esp8266/arduino library from Github makes it possible to program the ESP8266 microcontroller directly from the Arduino IDE, and provides some nice API functions as well. I ran the serial library's port discovery tool, and it listed /dev/cu.usbserial, so maybe that's the device we should be using:Ĭonnecting to serial port at /dev/cu.usbserial with timeout of 5 seconds: Test 4B: 115200 baud rate, RX on ESP8266 connected to RX on PL2302 (mini usb to serial board), CH_PD pin high Test 3B: 115200 baud rate, RX on ESP8266 connected to RX on PL2302 (mini usb to serial board), CH_PD pin floating Test 2B: 115200 baud rate, RX on ESP8266 connected to TX on PL2302 (mini usb to serial board), CH_PD pin high Test 1B: 115200 baud rate, RX on ESP8266 connected to TX on PL2302 (mini usb to serial board), CH_PD pin floating Test 4A: 57600 baud rate, RX on ESP8266 connected to RX on PL2302 (mini usb to serial board), CH_PD pin high Test 3A: 57600 baud rate, RX on ESP8266 connected to RX on PL2302 (mini usb to serial board), CH_PD pin floating Test 2A: 57600 baud rate, RX on ESP8266 connected to TX on PL2302 (mini usb to serial board), CH_PD pin high Test 1A: 57600 baud rate, RX on ESP8266 connected to TX on PL2302 (mini usb to serial board), CH_PD pin floating With this first set of experiments, I was connecting to the serial device at /dev/tty.usbserial.Ĭonnecting to serial port at /dev/tty.usbserial with timeout of 5 seconds: Baudrate - 57600 or 115200 (depending on chip/board version).I had to try a couple of combinations of different parameters. 2.1 Preparing Arduino to Work with ESP8266.
