I used the sample code to set up OTA for an Arduino R4 WiFi.
#include <SPI.h>
#include <WiFiS3.h>
#include <ArduinoOTA.h>
#include "arduino_secrets.h"
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
/////// Wifi Settings ///////
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password
int status = WL_IDLE_STATUS;
void setup() {
//Initialize serial:
Serial.begin(9600);
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue:
while (true);
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
}
// start the WiFi OTA library with internal (flash) based storage
ArduinoOTA.begin(WiFi.localIP(), "Arduino", "password", InternalStorage);
// you're connected now, so print out the status:
printWifiStatus();
}
void loop() {
// check for WiFi OTA updates
ArduinoOTA.poll();
// add your normal loop code below ...
}
void printWifiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
I am using the Arduino 1.8.13 IDE and can see the arduino under ports. I select it and when I upload a pop up window appears saying "Type board password to upload a new sketch".
I thought this should be password (the third parameter in the ArduinoOTA.begin() command. I have tried two different boards and every time I enter the password the pop up window just re-appears. There is a No Device found on in the console each time I enter the password. The arduino is powered up and connected to another computer with the serial window open to verify that I have the correct IP address. My laptop and the arduino R4 are both connected to the same wifi network. I have tried two different networks(the school I work at, which may have a firewall issue and my cell phone hotspot.)
What am I doing wrong?
New sketch is just to test that it works and turns an LED on and off:
#include <SPI.h>
#include <WiFiS3.h>
#include <ArduinoOTA.h>
#include "arduino_secrets.h"
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
/////// Wifi Settings ///////
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password
int status = WL_IDLE_STATUS;
const int ledPin = 8;
void setup() {
//Initialize serial:
Serial.begin(9600);
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue:
while (true);
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
}
// start the WiFi OTA library with internal (flash) based storage
ArduinoOTA.begin(WiFi.localIP(), "Arduino", "password", InternalStorage);
// you're connected now, so print out the status:
printWifiStatus();
pinMode(ledPin,OUTPUT);
}
void loop() {
// check for WiFi OTA updates
ArduinoOTA.poll();
// add your normal loop code below ...
digitalWrite(ledPin,HIGH);
delay(1000);
digitalWrite(ledPin,LOW);
delay(1000);
}
void printWifiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
}
