I’ve searched for hours now and I can’t seem to find the solution for my problem.
I know wemos isn’t supported by blynk but I also know that many managed to install the esp8266 standalone sketch and worked from there.
I’ve uploaded that sketch to my wemos, connected with usb serial connector and I see nothing on the serial monitor.
on the app it says the device isn’t online.
Can anyone help me with this?
any suggestion as to what I can do?
I tried changing the baud rate and nothing…
the wemos worked with regular sketches but now I want it to work with blynk and it doesn’t.
Hello dear.
In order to get efficiently help we need more info like:
Arduino IDE version, ESP8266 Arduino core Version, Blynk library version, Your pc operating system.
Also the sketch that you work with
Start with these for the start…
arduino IDE: 1.8.2
ESP8266 arduino core version: how do I get that information?
blynk library version: 0.4.8
OS: windows
and the sketch is the basic blynk example: ESP8266_standalone.
I only changed the token, ssid and password to match my own.
@Costas I see nothing!
I tried different baud rates… tried changing some of the upload settings and still nothing… not even just symbols… just nothing.

This example runs directly on ESP8266 chip.
Note: This requires ESP8266 support package:

Please be sure to select the right ESP8266 module
in the Tools -> Board menu!
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!

#define BLYNK_PRINT Serial

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "BLA BLA BLA";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "MY SSID";
char pass[] = "MY PASSWORD";
void setup()
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
}
void loop()
{
Blynk.run();
}
the caps are my information that obviously I changed.
I tried everything… but I’ll change it back to 115200.
I flashed the sketch 10 times already I think.
I see the COM port only if I connect the wemos through a us serial connector. through the USB I can’t see it… but again it worked with other sketches so that’s not the problem.
I’m not sure what is the new model but I have something that looks like this: http://www.cnx-software.com/wp-content/uploads/2016/02/Wemos_D1_mini.jpg
and I tried all the usb cables I have in the house… but again I can connect it through the usb serial connector…
Some fakes by their very nature don’t work. Has this particular ESP (i’ll not call it a WeMos) actually made any internet connections before you tried Blynk?
