Resurrecting an old Wemos Project

marine_hm · April 19, 2022, 3:00pm

I had this Project working back in 2016. The board stopped working after a friend took it home to show it off. It's been on the bench for some time now.
PaulRB ?
I dusted it off and purchased all new parts. Now the sketch does not compile.
I think it has to do with the IP4 being outdated?

I copied the original sketches from here: Audio fx trigger - #2 by marine_hm

Station Sketch

#include <ESP8266WiFi.h>

const char* ssid = "SoundFx";
const char* password = "Adafruit";

int ledPin = D1;
int triggerPin = D7;
WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  delay(10);

  pinMode(ledPin, OUTPUT);
  digitalWrite(ledPin, LOW);


  pinMode(triggerPin, OUTPUT);
  digitalWrite(triggerPin, HIGH);

  // Connect to WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);
  WiFi.mode(WIFI_STA);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    digitalWrite(ledPin, HIGH);
    Serial.print(".");
    delay(50);
    digitalWrite(ledPin, LOW);
  }
  Serial.println("");
  Serial.println("WiFi connected");

  // Start the server
  server.begin();
  Serial.print("Server started on ");
  Serial.println(WiFi.localIP());

  digitalWrite(ledPin, HIGH);
  delay(500);
  digitalWrite(ledPin, LOW);

}

void loop() {
  // Check if a client has connected
  WiFiClient client = server.available();
  if (client) {

    // Wait until the client sends some data
    Serial.println("new client");
    while (!client.available()) {
      delay(1);
    }

    // Read the first line of the request
    String request = client.readStringUntil('\r');
    Serial.println(request);
    client.flush();

    // Match the request

    int value = LOW;
    if (request.indexOf("/LED=ON") != -1) {
      digitalWrite(ledPin, HIGH);
      digitalWrite(triggerPin, LOW);
      value = HIGH;
    }
    if (request.indexOf("/LED=OFF") != -1) {
      digitalWrite(ledPin, LOW);
      digitalWrite(triggerPin, HIGH);
      value = LOW;
    }

    // Set ledPin according to the request
    //digitalWrite(ledPin, value);

    // Return the response
    client.println("HTTP/1.1 200 OK");
    client.println("Content-Type: text/html");
    client.println(""); // do not forget this one

    client.print("Led pin is now: ");

    if (value == HIGH) {
      client.print("On");
    } else {
      client.print("Off");
    }
    client.println(""); // do not forget this one

Here's the error I get when compiling the AP Sketch

try struct ip4_addr *IPaddress;

If you want to attract the attention of a forum member, you need to put @ before their name, like @marine_hm or @PaulRB. If you don't put the @, they won't get any notification. The forum software has changed since we collaborated on your project, I can't believe it was 6 years ago!

PaulRB · April 19, 2022, 5:46pm

I think @Juraj is correct, but you might also need to change:

    struct ip4_addr *IPaddress;

...
      IPaddress = &stat_info->ip;
      String host = String(ip4_addr1(&IPaddress)) + "." + ip4_addr2(&IPaddress) + "." + ip4_addr3(&IPaddress) + "." + ip4_addr4(&IPaddress);

You may be able also to install an older version of the ESP8266 arduino core software in the IDE, that is one which was current at the time you originally installed the sketch.

Error compiling for board LOLIN(WEMOS) D1 mini Pro.

Thanks for all the help.

@6v6gt : I probably could just roll back the version and be done with it. But then, I wouldn't have exercised my brain or conversed with a friend.

Let's try

String host = IP2STR(&IPaddress);

or

String host = IPAddress((&stat_info->ip)->addr).toString();

marine_hm · April 21, 2022, 1:39pm

This worked:
String host = IPAddress((&stat_info->ip)->addr).toString();

However, now it looks like the AP is trying to log in to the "Client" IP? Why?
This is what happens after the Station/Client gets plugged in and connects:

OK. I'm sure you noticed that my entire sketch changed. I was trying to create a whole new sketch on my own. Didn't work as I had imagined.

I applied the String host = IPAddress((&stat_info->ip)->addr).toString();
to the original sketch and it now works.

Very strange.... When I plug the Station into an A/C outlet with an iphone usb adapter, I have to press the reset button for it to work. If I plug it into my Laptop or Raspberry Pi USB. It works just fine? Could you give me some insight on that?

Plugging it into a PC probably resets the USB interface and generates an additional reset pulse.

From what I understand, Apple products usually only work with other Apple products, and that's how they make so much money.

How did you plug an Apple AC adapter into the wemos? Some wierd-Apple-connector-to-micro-usb adapter?

Did you try a normal AC to micro-usb adapter/charger?
