Arduino CLI with ESP8266

README.md

• Install Arduino IDE to /opt/arduino
• Install PubSubClient and MsgFlo
• Edit /opt/arduino/libraries/PubSubClient/src/PubSubClient.h and set a bigger buffer size (for example 512)
• Add ESP8266 board URL:

/opt/arduino/arduino --pref "boardsmanager.additional.urls=http://arduino.esp8266.com/stable/package_esp8266com_index.json" --save-prefs

• Install board package

/opt/arduino/arduino --install-boards esp8266:esp8266 --save-prefs

• Fix build-flash linking:

  • Edit packages/esp8266/hardware/esp8266/2.3.0/platform.txt
  • Replace {build.flash_ld} with eagle.flash.4m.ld

• Verify build: /opt/arduino/arduino -v --verify --board esp8266:esp8266:nodemcu --port /dev/ttyUSB0 sensor.ino

• Upload build: /opt/arduino/arduino -v --upload --board esp8266:esp8266:nodemcu --port /dev/ttyUSB0 sensor.ino

See also Arduino CLI docs https://github.com/arduino/Arduino/blob/master/build/shared/manpage.adoc

• Set up terminal connection with nodemcu-tool

./node_modules/.bin/nodemcu-tool -p /dev/ttyUSB0 -b 115200 terminal
