onto the ESP8266 with this setup:
For my serial output I get:
en 1384, room 16
tail 8
chksum 0x2d
csum 0x2d
v09f0c112
~ld
I got it to work semi successfully before now. I was basically following along with https://create.arduino.cc/projecthub/luciorocha/esp8266-control-led-with-smartphone-8a59f3. I got to the point where the code was being run successfully - but then something unexpected happened, when I thought the LED would go on, when I selected the turn on button, nothing happened. When I selected turn off, the blue LED on the board turned on and stayed steady. Then, when I selected turn on again, the LED on board went off. I thought the sketch was supposed to manipulate pin 2, but it seemed to be manipulating the onboard LED instead, and in the reverse way that it should.
Now, I can upload it, but the only thing it does after that is spit out the above serial output. I have tried running it with:
GND -> GND
VCC -> 3.3v
CH_PD -> 3.3v
Other sketches seem to work, so maybe something I did triggered an ESP8266 setting which now conflicts with something in the code?
UPDATE
I double checked that other sketches are running - also running is a sketch that connects the ESP8266 to my network - it connects and gets assigned an IP. I made this simplified sketch of the one above, involving the connection process:
/* Create a WiFi access point and provide a web server on it.
Author: Lucio A. Rocha
Last Update: 21 Aug 2016
*/
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
void setup() {
delay(1000);
Serial.begin(115200);
Serial.println();
Serial.print("Configuring access point...");
/* You can remove the password parameter if you want the AP to be open. */
WiFi.softAP("MaisonBlanche", "7932gLBw");
IPAddress myIP = WiFi.softAPIP();
Serial.print("AP IP address: ");
Serial.println(myIP);
}
void loop() {
}
The only thing it outputs (no connection) to serial is:
0, len 1384, room 16
tail 8
chksum 0x2d
csumcL⸮
~ld
So it seems as if the problem is with my code, or it is able to connect to a network as a client but not as a softAP?
UPDATE
I ran this code:
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
ESP8266WebServer server(80);
void setup()
{
Serial.begin(115200);
Serial.println();
Serial.print("Setting soft-AP ... ");
boolean result = WiFi.softAP("MaisonBlanche", "7932gLBw");
if(result == true)
{
Serial.println("Ready");
}
else
{
Serial.println("Failed!");
}
}
void loop()
{
Serial.printf("Stations connected = %d\n", WiFi.softAPgetStationNum());
delay(3000);
}
The same garbled serial output appears, and then it started outputting:
Stations connected = 0
Then the output changed to:
Stations connected = 1
Does this just mean it is successfully connecting using softAP?
UPDATE
I think I have narrowed it down what is not working to the ESP8266WebServer. I used this code:
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
ESP8266WebServer server(80);
void setup()
{
Serial.begin(115200);
Serial.println();
Serial.print("Setting soft-AP ... ");
boolean result = WiFi.softAP("MaisonBlanche", "7932gLBw");
if(result == true)
{
Serial.println("Ready");
}
else
{
Serial.println("Failed!");
}
server.on("/", handleRoot);
server.begin();
}
void handleRoot() {
int size=1000;
char temp[size];
int sec = millis() / 1000;
int min = sec / 60;
int hr = min / 60;
snprintf ( temp, size,
"<html>\
<head>\
<title>BEASTMODE</title>\
<style>\
body { background-color: #cccccc; font-family: Arial, Helvetica, Sans-Serif; Color: #000088; }\
</style>\
</head>\
<body>\
<h3>You are connected on BEASTMODE!</h3>\
</body>\
</html>",
hr, min % 60, sec % 60
);
server.send ( 200, "text/html", temp );
}
void loop()
{
Serial.printf("Stations connected = %d\n", WiFi.softAPgetStationNum());
//delay(3000);
Serial.print("Soft-AP IP address = ");
Serial.println(WiFi.softAPIP());
server.handleClient();
}
When the loop starts it begins to output:
Soft-AP IP address = 192.168.4.1
Stations connected = 0
It seems to go between 0 stations connected and 1 station connected. I go to 192.168.1.4 in my browser, and it never loads the page, it just times out. So if it has a softAP IP address - but it is not accessible, then maybe the server isn't working for some reason. Also I read how you can put the chip into different modes (STA/AP/etc
