[Solved] Arduino.org Uno WiFi board with Firmware 1.0.0 and WiFiLink.h Librairies

I connected to your Uno from here with a few mods - see PM.

@Costas could you explain the solution please (if there is one) ?

@vshymanskyy my connection was with a WeMos rather than the Uno board.

The fact that @Emmanuel_Leroy is getting the incorrect token suggests to me he his almost there. Surely if he gets this then WiFi works and connection has been made to your server. Any reason why this Uno board can’t send a valid token?

Do you have any Uno WiFi boards at Blynk?


The WiFiLink Library works as the Library WiFi.
Do you think it is possible to adapt the Arduino_WiFi_Shield for working with the WifiLink.h library?

I downloaded the WiFiLink.h library last night and added the Arduino Uno WiFi board in the IDE to carry out some tests.

I don’t have the board so I can only test so far.

Try adding the following as the first line of code to the sketch that gave “incorrect token” (your first sketch ensuing cloud server and correct port are included in the sketch etc).


Then paste SM (Serial Monitor) data.

You should see something like this but without the NodeMCU references. Be sure to remove your live token references in any sketch or SM data you post.

where i must put the #define

Have you noticed the virtual LED going on and off in your app?

Got your PM.

yes my Widget led blink 3 time


Your token should start and end with a 9.


That looks better but you are missing the first 2 digits from the front of the token.

Does the sketch have the correct token or is it just SM / Blynk that is losing the first 2 digits?

I just saw this anomaly, the token is yet complete in my sketch

OK I will see if I can spot anything in the WiFiLink.h library.

You are sooooooooooooo close.

Can’t see anything and thinking about it your WiFi looks fine. Will see if there is anything in BlynkSimpleStream.h that is causing the anomaly.

@vshymanskyy ignore my last PM, @Emmanuel_Leroy has hacked the libraries and it’s now connecting.

@Emmanuel_Leroy please post the library hack and a final sketch here and perhaps edit the first sketch in this thread to include the final sketch.

Be sure to remove any tokens etc but it would be nice to see your final Serial Monitor (less tokens).

Did you have to flash firmware 1.0.0 before you started working with Blynk? I downloaded the firmware last night but if it’s required please post a link.

Finally It’s a great news !

I just adapt the BlynkSimpleWifi.h sketch in a BlynkSimpleWifiLink.h and put in the src folder of Blynk library

And to use the example of Blynk using a LED widget on your phone!

       Download latest Blynk library here:

       Blynk is a platform with iOS and Android apps to control
       Arduino, Raspberry Pi and the likes over the Internet.
       You can easily build graphic interfaces for all your
       projects by simply dragging and dropping widgets.

@Emmanuel_Leroy thank you for great news, we will add Arduino UNO WiFi support soon!
