Over-the-Air (OTA) update

There are 2 options:

• Directly specify platformio run --upload-port in command line

platformio run --target upload --upload-port IP_ADDRESS_HERE or mDNS_NAME.local

• Specify upload_port option in Project Configuration File platformio.ini

[env:myenv]
upload_port = IP_ADDRESS_HERE or mDNS_NAME.local

For example,

• platformio run -t upload --upload-port 192.168.0.255
• platformio run -t upload --upload-port myesp8266.local

Authentication and upload options

You can pass additional options/flags to OTA uploader using upload_flags option in Project Configuration File platformio.ini

[env:myenv]
upload_flags = --port=8266

Available flags

• --port=ESP_PORT ESP8266 OTA Port. Default 8266
• --auth=AUTH Set authentication password
• --spiffs Use this option to transmit a SPIFFS image and do not flash the module

For the full list with available options please run

~/.platformio/packages/tool-espotapy/espota.py -h

Usage: espota.py [options]

Transmit image over the air to the esp8266 module with OTA support.

Options:
  -h, --help            show this help message and exit

  Destination:
    -i ESP_IP, --ip=ESP_IP
                        ESP8266 IP Address.
    -p ESP_PORT, --port=ESP_PORT
                        ESP8266 ota Port. Default 8266

  Authentication:
    -a AUTH, --auth=AUTH
                        Set authentication password.

  Image:
    -f FILE, --file=FILE
                        Image file.
    -s, --spiffs        Use this option to transmit a SPIFFS image and do not
                        flash the module.

  Output:
    -d, --debug         Show debug output. And override loglevel with debug.
    -r, --progress      Show progress output. Does not work for ArduinoIDE

Using Arduino Framework with Staging version

PlatformIO will install the latest Arduino Core for ESP32 from https://github.com/espressif/arduino-esp32. The Git should be installed in a system. To update Arduino Core to the latest revision, please use platformio platform update command.

1. Install Espressif 32 (Stage) development platform

platformio platform install https://github.com/platformio/platform-espressif32.git#feature/stage

2. Set platform to espressif32_stage in Project Configuration File platformio.ini. For example,

   [env:esp32dev]
   platform = espressif32_stage
   board = esp32dev
   framework = arduino
   

3. Try to build project

4. If you see build errors, then try to build this project using the same stage with Arduino IDE

5. If it works with Arduino IDE but doesn’t work with PlatformIO, then please file new issue with attached information:

   • test project/files
   • detailed log of build process from Arduino IDE (please copy it from console to http://pastebin.com)
   • detailed log of build process from PlatformIO Build System ( please copy it from console to http://pastebin.com)

Examples

All project examples are located in PlatformIO repository Examples for Espressif 32 platform.
