Does anyone know how to setup a webserver for Portenta Machine Control for remote monitoring?
There is no documentation or existing example yet.
I tried this sketch and there is no error in the output. But I typed in the IP address in the web browser and there's no response. I ping the IP address and there is no response as well.
Not sure if I'm missing anything.
Here is the sketch
#include <Arduino_MachineControl.h>
#include <WiFi.h>
#include "arduino_secrets.h"
using namespace machinecontrol;
///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS;
WiFiServer server(80);
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Access Point Web Server");
// pinMode(LEDR,OUTPUT);
// pinMode(LEDG,OUTPUT);
// pinMode(LEDB,OUTPUT);
// by default the local IP address of will be 192.168.3.1
// you can override it with the following:
WiFi.config(IPAddress(192, 168, 1, 21));
if(strlen(pass) < 8){
Serial.println("Creating access point failed");
Serial.println("The Wi-Fi password must be at least 8 characters long");
// don't continue
while(true);
}
// print the network name (SSID);
Serial.print("Creating access point named: ");
Serial.println(ssid);
//Create the Access point
status = WiFi.beginAP(ssid,pass);
if(status != WL_AP_LISTENING){
Serial.println("Creating access point failed");
// don't continue
while (true);
}
// wait 10 seconds for connection:
delay(10000);
// start the web server on port 80
server.begin();
// you're connected now, so print out the status
printWiFiStatus();
}
void loop() {
// compare the previous status to the current status
if (status != WiFi.status()) {
// it has changed update the variable
status = WiFi.status();
if (status == WL_AP_CONNECTED) {
// a device has connected to the AP
Serial.println("Device connected to AP");
} else {
// a device has disconnected from the AP, and we are back in listening mode
Serial.println("Device disconnected from AP");
}
}
WiFiClient client = server.available(); // listen for incoming clients
if (client) { // if you get a client,
Serial.println("new client"); // print a message out the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
if (client.available()) { // if there's bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
if (c == '\n') { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that's the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what's coming, then a blank line:
client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");
client.println();
// the content of the HTTP response follows the header:
client.print("<html><head>");
client.print("<style>");
client.print("* { font-family: sans-serif;}");
client.print("body { padding: 2em; font-size: 2em; text-align: center;}");
client.print("a { -webkit-appearance: button;-moz-appearance: button;appearance: button;text-decoration: none;color: initial; padding: 25px;} #red{color:red;} #green{color:green;} #blue{color:blue;}");
client.print("</style></head>");
client.print("<body><h1> LED CONTROLS </h1>");
client.print("<h2><span id=\"red\">RED </span> LED </h2>");
client.print("<a href=\"/Hr\">ON</a> <a href=\"/Lr\">OFF</a>");

client.print("<h2> <span id=\"blue\">BLUE</span> LED </h2>");
client.print("<a href=\"/Hb\">ON</a> <a href=\"/Lb\">OFF</a>");
client.print("</body></html>");
// The HTTP response ends with another blank line:
client.println();
// break out of the while loop:
break;
} else { // if you got a newline, then clear currentLine:
currentLine = "";
}
} else if (c != '\r') { // if you got anything else but a carriage return character,
currentLine += c; // add it to the end of the currentLine
}
// Check to see if the client request was "GET /H" or "GET /L":
if (currentLine.endsWith("GET /Hr")) {
// digitalWrite(LEDR, LOW); // GET /Hr turns the Red LED on
}
if (currentLine.endsWith("GET /Lr")) {
