When you’re writing a PlatformIO firmware that can be uploaded using both ArduinoOTA and over the serial port, I recommend this platformio.ini setup:
Start with your normal config for serial upload:
[env:d1_mini] platform = espressif8266 board = d1_mini framework = arduino monitor_speed = 115200
And now add a new OTA target that extends the serial config, effectively inheriting the complete build configuration including the lib_deps:
[env:d1_mini_ota] extends = env:d1_mini upload_protocol = espota upload_port = 192.168.178.166
In upload_port you need to enter either the IP address or the mDNS name of the board that shall be flashed. The IP address we entered (192.168.178.166) is just an example.
Also note that depending on the name of your original build target, change
extends = env:d1_mini
to the name of your original target (including env:)
Complete platformio.ini example
[env:d1_mini] platform = espressif8266 board = d1_mini framework = arduino monitor_speed = 115200 [env:d1_mini_ota] extends = env:d1_mini upload_protocol = espota upload_port = 10.9.1.106
