• Description:
Often times we need to report data collected from sensors to a 'central' location for long-term storage, analysis, and/or visualization. Typically, we use cloud services such as Thingspeak, myDevices Cayenne, or Ubidots for this purpose. However, it is possible to dedicate an ESP8266 to carry out these tasks.
In this video, we configure an ESP8266 as a WiFi Access Point so that client devices can connect to it. In addition, we set up a web server with a couple of access routes, so that the clients can send data to it using URL parameters ( • ESP8266 Control NeoPix... ). This is the simplest way to collect data from multiple devices and send them to a 'central' location even in the absence of an internet connection!
We also configure a client device to use the low-power (deep sleep) mode between data measurements, and wire it so that the ESP8266 resets itself to perform the measurements continuously!

@paulgibby6932 5 років тому

Thanks! That was cool. I like the music too. I am not clear on "who" initiates getting the temperature value. Wouldn't it make sense to have the server poll for a new value only when it receives an "update" request?

@datasith 5 років тому

Hey, Paul. Thanks, I'm glad you liked it. In this case, I set it up so that the measurements occur periodically. The interval it's determined by the amount of time for which the client goes to sleep. In the example, every two seconds, but could be made longer depending on the application. Your polling proposal is great, but it'd be slightly harder to coordinate with the waking up of the client.

Hi, friend, excellent tutorial, however I got some questions about the ip adresses you define, how do you define them?, I mean, is it a random group of ip addresses the ones we can use or they have to be chosen according to some factors?

@datasith 4 роки тому

Thank you, I'm glad you liked it! The IP addresses that I defined are random-ish. I'm using the group of addresses typically used for local networks (192.168.X.X). I could use any IP possible, for example 8.8.8.8 (Google's servers) but the clients would get confused between the 'real IP' and the local one so you'd need to do additional steps. HTH!

Thanks for the excellent introduction to the ESP8266. I am having a bit of a problem setting the server IP address, using the command "Serial.println (WiFi.LocalIP() );" , results in "IP Address: IP unset)" being printed on the serial monitor. Secondly the name listed on the computers network page is "ESP-24F8D6" instead of the "ESP8266-SSID" used within the code. Everything in the code looks identical to that illustrated in your video. Everything else appears to work as I can see when the second ESP8266 logs in and out as a client. Just unable to set the Servers IP Address.

@devtn5543 4 роки тому

how to fix IP unset . Help me ....

@datasith 4 роки тому

Hey, Tom. Maybe your own WiFi network is running on subnet 11 and causing problems? Try switching the 11 to something else (between 1 and 250) on the following lines: IPAddress ip(192,168,11,4); IPAddress gateway(192,168,11,1); HTH!

Re-flash your code into the ESP8266. If the error persists you could do something like: if( !WiFi.localIP().isSet() || !WiFi.isConnected() ){ Serial.println( F("Handeling WiFi Reconnect Manually.") ); WiFi.reconnect(); } I've never seen this on any of my projects, so I had to read about it online and it doesn't seem to have a better solution.

@kevinroach9380 5 років тому

What is the typical Wifi range for this setup? Also if I wanted to add a sd card to store weather reading does the server need to be refreshed to save the values every 1/2 an hour etc. to the sd card?

@tin2001 5 років тому

Range is highly dependent on the 2.4GHz congestion in your local area. For storing weather data, you'd want to have either the storage node scheduled to poll the sensor nodes, or the sensor nodes scheduled to push their data back (and then have the storage node save the data to the SD card in its handler for the web request).

Hey, awesome project. You can do it in different ways, the simplest in my opinion is to serve the website from the board that's running the server code. When the user clicks the button on that website, then it can make that available for (or send it to) the client board. hth!

Hi, I configured the esp8266 wifi module as an access point, then docklight scripting V2.2 connected esp866 with 192.168.4.1:1025 port and send data periodically 0.5 second to server. But server read data and it breaks off in a few seconds. How can I prevent the server from going down.

@datasith 3 роки тому

usually when thinks "break off" is due to the way you're communicating the data. if you're "polling" continuously in the loop function you can disrupt other functionality including the wi-fi connectivity. it's better to either use asynchronous communication or a second core if you're using the ESP32, for example.

@@JenishJain6 that's correct, Jenish. server.begin() will allow the client to listen to incoming requests! You could also get rid of the client side, and just use server.begin() for listening, and send the data using server.send(). I'm just mentioning options, your original approach should work well too!

@@datasith also making one of the esp as a web server with this code, some of the times a problem occurs i.e. its IP is unset sometimes thus i am not able to connect to the webpage hosted on esp. I have tried using a static IP for it but thought the problem persists. is their any solution to it.

it works for me but i do not need to enter the password in order to connect to it, am i missing something to impliment a password.

@datasith 4 роки тому

Yeah, this is just sending requests over HTTP which the server is expecting. You'd need to add some form of authentication on top of that. HTH!

Excellent tutorial but is there a link to the code?

Can we Encrypt transferring data ? Need encryption tutorial toooooo.

@datasith 4 роки тому

You can use HTTPS as well, although the encryption isn't the most secure. If you pursue it, your life will be a lot easier using the ESP32 (better TLS support).

Yes, it is! The same code should work with minor modifications. See this video for an example on how the code changes between the ESP8266 and ESP32: ukposts.info/have/v-deo/aYeirYN9bYCU1Kc.html

Better solution use NRF24L01 module, this is designed for point to point communication.

@datasith 5 років тому

No need to flex, your suggestion isn't better in context. This is an ESP8266 application, not a "best practices for point-to-point communication."

@tin2001 5 років тому

This project example can be easily expanded to having dozens of "client" nodes, and could even be expanded to running over a larger LAN or even the internet (security aspects would need examining before doing that). A short range point to point radio module can't.

The tutorial is very good at explaining the HOW, and very weak in explaining the WHY. This is doing without understanding, or 'parroting'. Learning is understanding WHY things are done.
