Compiling and Uploading

Compiling using Arduino CLI

It is recommended to use the Arduino CLI for compiling and uploading your sketch.

When using Arduino CLI, the sketch dependencies are managed; They are automatically downloaded and installed in in isolated folder when compiling.

Dependencies on cores and libraries are defined in sketch.yml.

To compile using the default profile (for generic ESP8266 modules):

arduino-cli compile

Uploading

First, list connected boards:

arduino-cli board list

Then, compile and upload after setting your desired port:

arduino-cli compile -u -p [YOUR_PORT]

Using Arduino IDE 1

Installing core

Follow these instructions to install the ESP8266 core to the Arduino IDE board manager: https://github.com/esp8266/Arduino#installing-with-boards-manager

Installing Libraries

Arduino IDE 1 has no way of automatically managing and installing sketch dependencies from sketch.yml.

Please refer to sketch.yml to install the correct cores and dependencies.
