Arduino nano 33 IOT over the air update (OTA)

t.akca38 · May 6, 2024, 8:29am

Hi,

i decided to leave the arduino IDE and use platformio. i want to use OTA updates, with the arduino IDE i can choose between serial upload via com or network port shows up. See picture below:

using de platformio the code uploads succesfully but i cant seem to find the place to upload “OTA” . only the com port shows up , also not with multicast DNS

i think i am doing something wrong now

The Arduino IDE uses the arduinoOTA program to upload it wirelesssly.

          arduinoota.extraflags=
          tools.arduino_ota.cmd={runtime.tools.arduinoOTA.path}/bin/arduinoOTA
          tools.arduino_ota.upload.field.password=Password
          tools.arduino_ota.upload.field.password.secret=true
          tools.arduino_ota.upload.pattern="{cmd}" -address "{upload.port.address}" -port 65280 -username arduino -password "{upload.field.password}" -sketch "{build.path}/{build.project_name}.bin" -upload /sketch -b {arduinoota.extraflags}

Currently, PlatformIO doesn’t have native support for it.

So you have to go the route with the custom upload_command.

Try something of the sort

upload_protocol = custom
; CORRECT IP HERE
upload_port = 192.168.0.123
upload_flags =
    -address
    $UPLOAD_PORT
    -port
    65280
    -username
    arduino
    -password
    ""
upload_command = arduinoOTA $UPLOAD_FLAGS -sketch $SOURCE -upload /sketch -b

You’ll have to find the arduinoOTA.exe executable though in your Arduino IDE installation folder and either copy it in the root of the project folder or reference the full path to it in the upload_command.
