PlatformIO OTA Problem

I have a problem trying to upload cpp code to my Wemos D1 mini using OTA in VSC.

I have used OTA in Arduino IDE for some time & that works fine.

When trying the same thing in in VSC the program says

Uploading 1-100%
Waiting for Result
Result OK

BUT after that the Wemos will not boot, so it seems as if something is wrong or incomplete with the upload…

The software is just cut and paste from Arduino IDE, where it works,
(and works fine in VSC when uploaded via COM Port)…



platform = espressif8266
board = d1_mini

framework = arduino
;upload_port = COM[5]

upload_port =
;monitor_speed = 115200
;monitor_port = COM5
upload_protocol = espota
;each upload flag in a new line
;upload_flags =
; --auth=xxxxxx

Here is part of the output

When I change the platformio.ini to enable upload via cable (COM5) instead of via IP, it uploads ok, reboots and everything works fine, (but unfortunately not via IP-address/OTA)…

Any ideas ??

What sort of debuggging have you done for this so far? Have you tried going back to the BasicOTA example sketch, and seeing if that works with the necessary change to WiFi SSID and password? Is the device actually booting - is there any serial debug messages being output? What is the bootloader output (serial baud 74800) when the esp8266 starts up after OTA programming?

The fact you said it worked when you programmed via serial, and it worked then but with no IP/OTA sounds odd… no response from the device if you ping it via the command line?

For me, I can’t say I’ve had any issues with OTA and PIO (that weren’t self-inflicted :laughing:) … something like this works just fine for me… but I can’t see anything wrong in your config.
