Unable to compile Arduino Code with ArduinoOTA.begin()

[mskressin]

I am sorry if this is a dumb mistake on my part, but I cannot figure out what I am doing wrong. When I try the compile using IDE 2.2.0 the following code I am getting the error: "Compilation error: 'ArduinoOTA' was not declared in this scope" I have installed via the library manager ArduinoOTA version 1.0.10 and the board package for my Uno R4 WIFI board (version 1.02). I also followed the install instructions and copied the file platform.local.txt from the extras/renesas folder to the board install folder renesas_uno/1.02.

Simple code I am trying to compile:

include

include

const char ssid = "MyRouter"; // Change to your WiFi Network name const char password = "MyPassword";

void setup() { Serial.begin(115200); WiFi.begin(ssid, password);

// Ensure WiFi is connected while (WiFi.status() != WL_CONNECTED) { delay(500); } ArduinoOTA.begin(); }

void loop() { ArduinoOTA.handle(); // Handles a code update request delay(1000); }

Compiling this gives me the following error: In function 'void setup()': error: 'ArduinoOTA' was not declared in this scope ArduinoOTA.begin(); ^~~~~~ note: suggested alternative: 'ArduinoOTAClass'

Using library ArduinoOTA at version 1.0.10 in folder: Documents/Arduino/libraries/ArduinoOTA Using library WiFiS3 at version 0.0.0 in folder: Library/Arduino15/packages/arduino/hardware/renesas_uno/1.0.2/libraries/WiFiS3 exit status 1

Compilation error: 'ArduinoOTA' was not declared in this scope

Uno R4 support is in 1.0.11 which is not yet published to Library Manager

I uninstalled 1.0.10 and installed 1.0.11 via the library manager and still have the same error. Am I doing something wrong?

Error: Using library ArduinoOTA at version 1.0.11 in folder:
Using library WiFiS3 at version 0.0.0 in folder: Compilation error: 'ArduinoOTA' was not declared in this scope

open the WiFi101_OTA example and change the WiFiNINA include to WiFiS3. does that compile?

Thanks, that help me track down the problem. It seems the include order is critical. I had:

include

include

But it needed:

include

include

Has do do with the way that the code in ArduinoOTA is defining the class:

elif defined(WiFiNINA_h) || defined(WIFI_H) || defined(WiFiS3_h) || defined(ESP8266) || defined(ESP32) || defined(ARDUINO_RASPBERRY_PI_PICO_W) // NINA, WiFi101 and Espressif WiFi

ifdef NO_OTA_PORT

ArduinoOTAClass <WiFiServer, WiFiClient> ArduinoOTA;

else

include

ArduinoOTAMdnsClass <WiFiServer, WiFiClient, WiFiUDP> ArduinoOTA;

endif

Apparently, the pre-complier could not deal with the fact that variable WiFiS3_h was defined after the header file was included. Makes sense now that I found it. Thanks again for your help.
