Using a 2.9 inch E-Paper Display with ARDUINO

[Marc DANIEL]

No, my phone can't find the WIFI module but when I use this simple little program, it finds it.
And I too, I had only changed the SSID and password lines

 

[Marc DANIEL]

So I have fun with the EPaper ESP8266 LEDs and this in B4R

 

[Marc DANIEL]

I found in the B4R documentation this little B4R application which works very well with "EPaper ESP8266 Driver Board", my Smartphone finds "ESP" and connects without password.
Then I can display on the serial monitor the IP address by pressing the RESET button on the module

So, as I cannot obtain the same results with "Loader.ino", I think that either I did not understand all the manipulations that had to be carried out, or there is a bug in this application

Download the user manual

​

In this video provided by Waveshare, there is a CPP module "srvr.h" on which you must modify the SSID and Password lines, but on the files provided for download, this module "srvr.h" does not exist and it is on the "Loader.ino" file itself that these lines are available. So there is something that does not match in the video demonstration

I am not sure where your problem is.
I re-ran the Loader.ino (with the changes I did in post #77 & #80) and my laptop and phone browsers can find it at the address I specified (192.168.0.189).

 

[Marc DANIEL]

OK, so everything is working normally for you. The problem may be with my desktop PC, I will resume the tests with my laptop connected via WIFI

 

[Marc DANIEL]

So, I installed ARDUINO IDE on my laptop, which took a long time since I had to install the necessary libraries and then I had an unrecognized port problem and I had to find the right drivers for it to work. The USB port where ESP8266 was connected is finally recognized. After all this, to my great surprise, the Arduino Loader.Ino sketch executed correctly and then the "EPaper ESP8266 module" was detected by my laptop and my Smartphone.

But now, if I can connect to the WIFI network of "EPaper ESP8266", I cannot download the html application because either my antivirus blocks me, or other technical reasons prevent my access to this application . But there is progress.

And I still don't understand why I couldn't get these results on my desktop PC. Thank you for encouraging me to find the probable reasons for the technical blockage.

 

[Daestrum]

Sorry, I am getting confused.

Your home wifi network is called "EPaper ESP8266" ?

 

[Marc DANIEL]

Yes "EPaperESP8266" . I'm the one who named it that

 

[Daestrum]

Ok, was just trying to clarify that it's not something just in the esp8266, it's actually what the router wifi was called.

I'm struggling with my BitDefender antivirus which is evil and blocks everything, it even deleted zip files that I needed

 

[Marc DANIEL]

My Smartphone disconnects too quickly from the ESP8266 Wifi, I don't even have time to open a browser with "http://192.168.4.22" because my Smartphone has already reconnected to my usual box. I don't know how you manage to get the html display integrated into the module

 

[Daestrum]

Just so I am sure
1, Your router wifi ssid is called "EPaperESP8266"
2, You power up the Esp and it connects to your wifi ok - serial monitor should say web server/service started
3, you open a browser "http://192.168.4.22"

 

[Marc DANIEL]

Yes, all this is correct, my problem is that the connection to wifi of ESP8266 only lasts a few seconds and therefore I do not have time to open a browser. I have to turn off my box to prevent automatic reconnection too quickly but I will do it this evening because everything works on this box in the house...

 

[Daestrum]

I am still stuggling to visualise whats occuring.

You have two routers in your home, one has ssid "EPaperESP8266" the other is your 'normal' wifi ssid ?

You do not connect to the esp via wifi directly, you use your 'normal' wifi, the esp requests an ip address and you connect the phone to your 'normal' wifi and use the browser to navigate to "http://192.168.4.22"

 

[Marc DANIEL]

No, I'm just trying to connect directly to the WIFI of "EPaperESP8266" but my router (my box) is disrupting this. So, tonight, I'm going to turn off the box so I can continue my connection tests.

[Daestrum]

I think I understand now - you took out the STA mode and are using AP mode instead.

 

[Marc DANIEL]

So you think that's the problem? What should I do to fix it?

 

[Daestrum]

I will try putting mine into Ap mode.

As a thought, if your home wifi is 192.168... try using 10.0.0.22 on the esp

 

[Marc DANIEL]

Sorry for not responding sooner.
I noticed that my tablet remains connected to EPaperESP8266 and so I had time to open a browser and type the address 192.168.4.22 and unfortunately I get the error message below:

Then I tried 10.0.0.22 and several other IP addresses but got the same response. So I remain "paralyzed"...
Thank you for your much appreciated help.

 

[Marc DANIEL]

I connected to the WIFI of EPaperESP8266 this morning with my laptop then I displayed the properties of this connection, here is the screenshot:

STA or AP ?
