ESP8266 web communication problem

[Ranbeer Singh]

Hello,

I was working with ESP8266 wifi module. I have successfully connected it with PC and my phone via hostpot. It's responding according to AT command with UART communication but it is not founding when i search it's wifi address with web browser.

I sets undermentioned AT commands.

AT+CWMODE=3;
AT+CIPMODE=0;
AT+CIPMUX=1;

AT+CWJAP="SSID","PASSWORD";

When i send AT+CWJAP? inquiry command, it sends SSID name and when i send AT+SIFSR? command it send back me that it got a IP address. I think it's ok.

AT for making a server

AT+CIPSTO=180;
AT+CIPSERVER=1,1234;


No error massage occurred by module. All time comes OK response.

I am wonder, where am i wrong?



Please advice.

I am using station IP address in web browser.

Hay can you try using station IP and port number in web browser? Like if your station IP is 192.168.1.10 and here in your device server opened on port number 1234, so try "192.168.1.10:1234" in your browser.

Hi,

No, I tried it without port number like 192.168.1.10. I tried it with Arduino IDE sketch program also. But nothing is happening.

In web browser if you type IP address without the port number, it will by default try asking server for the connection on the port number 80. Here in your ESP module when you try AT command :

AT+CIPSERVER=1,1234;

You are actually opening server on port number 1234.

So from web browser you need to specifically ask this port number instead of default port number 80. And for that you need to type "192.168.1.10:1234" in your web browser. Please try this and update the result.

Hello Dhruv,

I tried according to your instruction, I changed port 80 instead of 1234. But nothing is happening in both cases. I updated ESP8266 (32MB flash) according to this site https://developer.mbed.org/users/sschocke/code/WiFiLamp/wiki/Updating-ESP8266-Firmware.

Is some other setting will be need that i have forgot?
Is this module damage?

Hi Ranbeer,

If you are doing according to what you have mention, I think you are doing fine. Even if you are not getting the results then you need to check it step by step. If you are ok with that then please follow this.

1. I advice you to post this on ESP community forum "here" as well, so no stone upturned. Also do back linking in both for reference.
2. Please strictly follow this steps: (This is what gave me success on my module)
   
   

   // Reset the device
   AT+RST\r\n
   
   // Restore the device
   AT+RESTORE\r\n
   
   // Get version info
   AT+GMR\r\n
   
   // Set WiFi mode as station mode
   AT+CWMODE_CUR=1\r\n
   
   // List available APs 
   AT+CWLAP\r\n
   
   // Connect to AP, for current
   AT+CWJAP_CUR="YourSSID","YourPassword"\r\n
   
   // Check network connection status
   AT+CIPSTATUS\r\n
   
   // Get local IP address (Please note down the IP)
   AT+CIFSR\r\n
   
   // Show remote IP and port with "+IPD" (optional but try for now)
   AT+CIPDINFO=1\r\n
   
   // Enable multiple connections
   AT+CIPMUX=1\r\n
   
   // Configure as TCP server
   AT+CIPSERVER=1,80\r\n
   
   // Check network connection status
   AT+CIPSTATUS\r\n

3. If all goes well at this point you may go to your browser and try to connect to the IP address you received in the response of "AT+CIFSR".
4. Check again network status
   

   // Check network connection status
   AT+CIPSTATUS\r\n

5. If you have been successful up to this point, you may reply to your browser query by this:
   

   // Send data
   AT+CIPSEND=<YourLinkID>,3$0D$0A
   
   // data
   123
   
   // Close TCP connection
   AT+CIPCLOSE=<YourLinkID>\r\n
   
   // Check network connection status
   AT+CIPSTATUS\r\n

6. Please try all the steps and post the responses from module / device here.
7. Cross check the responses with the AT command manual, if anything is wrong.

Note:

• YourSSID == Your WiFi name.
• YourPassword == Your WiFi Password
• <YourLinkID> == ID number of connection (0~4) (5 will close all the connection).

I gave up on AT command firmware, and switched to Arduino based development of firmware for ESP8266. I highly recommend that to you as well.

Very nice reply ....

I will try with your suggested points and will report.

Hello,

These codes are working, Although i changed and/or skip some point.

My working ESP8266 configuration codes are given below.

void config_ESP8266()
{
	char a[7];
	char index = 0, val = 1;

	while(val)
	{
		if(esp8266_isStarted() == 0)
		{
			a[0] = esp8266_restart();
			a[1] = esp8266_echoCmds(0);
			a[2] = client_or_server(1);
			a[3] = esp8266_connect(id, password);
			a[4] = check_wifi_in_range();
			a[5] = Single_Multi(1);
			a[6] = Set_Server();

			while(index<7)
			{
				if(a[index] == 0) val = 0;
				else { val = 1; }
				index++;
			}
		}
	}
}
