I'm trying to make an OTA on my ESP32. The cpp is OK and manually triggering the update works fine but when I click on VS Code on the "Upload" button, it defaults to "COMx" instead of the given IP.

Manual call:

python C:\Users\<user>\.platformio\packages\framework-arduinoespressif32\tools\espota.py --ip 192.168.178.51 --port 3232 --timeout 60 --file "firmware.bin" --debug

this works perfectly, I get the given firmware on my ESP.

Call via VS Code:

What I want now is to trigger the upload using PlatformIOs IDE buttons on VS code.

My plaftormio.ini file:

[env:az-delivery-devkit-v4]
platform = espressif32
board = az-delivery-devkit-v4
framework = arduino
upload_port = 192.168.178.51
monitor_speed = 115200
; OTA
upload_protocol = espota
upload_flags =
    --port=3232
board_build.partitions = min_spiffs.csv
build_unflags = -Os
lib_compat_mode = strict
lib_deps =

    knolleary/PubSubClient@^2.8

    paulstoffregen/OneWire@^2.3.8
    milesburton/DallasTemperature@^3.11.0
    thomasfredericks/Bounce2@^2.72

I build the project -> all OK

When I click on UPLOAD, on the terminal I see:

Executing task: C:\Users\<user>\.platformio\penv\Scripts\platformio.exe run --target upload --upload-port COM5

Then it fails with the following information:

Why is the Upload-button not reading the target IP as set on the platformio.ini file and kept fixed to my COM5 (The serial port where my ESP32 was connected to when doing the initial download)? I already disconnected the ESP32 from my COM5 but PlatformIO is still defaulting to it.

I've removed and reinstalled the platformio IDE on VS Code, but the problem persists.

Any ideas how to fix this?

The problem was the "Set upload/monitor/test port" on VS Code was not set to AUTO, but to COM5.

Setting it to AUTO fixed the issue.
