OTA [ERROR]: No Answer

1

Hello. I have a problem with OTA and Platformio. With IDE Arduino run correct.
I desactive fireware and my platformio.ini is:

[env:d1_mini]
platform = espressif8266
board = d1_mini
framework = arduino
lib_deps =
  #Using a library name
  PubSubClient

; Serial Monitor options
monitor_speed = 115200

; Configuración OTA
upload_port = 192.168.1.150
upload_protocol = espota

In my setup() funtion:

........
........
 //Actualización código por OTA
  ArduinoOTA.setPort(8266);
  ArduinoOTA.setHostname("Control_Acceso");
  ArduinoOTA.begin();

In my loop() funtion:

........
........
ArduinoOTA.handle(); // Actualización código por OTA

Fixed IP: 192.168.1.150 in the code.

Mistakes:

I have read everything related to OTA in the forum but I can’t find a solution, please help

Can you ping this IP, as a first test? What is the full sketch? Have you tried the official example sketch first with PIO? Arduino/libraries/ArduinoOTA/examples/BasicOTA/BasicOTA.ino at master · esp8266/Arduino · GitHub

There is also no need for ArduinoOTA.setPort(8266); unless you want a port other than 8266, as this is the port the ArduinoOTA code will default to. I would be checking that the IP is pingable and that your firewall isn’t blocking access, assuming that you have tested this to be working with the stock example sketch first to make sure the fault isn’t somewhere in your code.

I have tried BasicOTA.ino and error.

With Arduino IDE BasicOTA.ino run ok.

¿Help please? I would like works with Platformio and OTA.

SOLVED

Problem with Firewall. I have given permisions to Visual Studio Code to use ports.

THANKS
