[SOLVED] Arduino Uno + CC3000 + App

Issues and Errors
1

I connected a Uno via a CC3000 Shield and created a simple LED on/off sketch
On the Android App when I choose Uno it says uno not connected ,
I am running a local server which works as I have ESP8266’s connected and the Uno’s serial port says it is connected .
Anyone with clues please
I basically want to use the CC3000 as the sketch prototype before I implement it to the ESP8266.

@Roger

Post your (correctly-formatted) code.

3

Actually there is no code in my post .
Only the output from the Arduino Uno’s serial port.

4

Let me rephrase this question.
I have an Arduino Uno and a CC3000 WiFi Shield , which device do I choose on the Android Blynk App ?

5

@Roger I think what @zeeko is suggesting is we need to see your code before we can suggest a solution.

6

Ah Ok let me figure out how to format and post, thanks. :relaxed:

If you are using an Uno then select Uno in the Blynk app. When you move from Uno to ESP you will need to create a new app for ESP. I have switched hardware against a single app previously but I don’t think that is recommended and it only takes a couple of minutes to recreate a new app.

Code formatting is done with the </> icon.

Thanks @Costas
I got it working just now realized I had put a statement in the wrong part of the code.
Anyways for anyone wanting to play around with an Uno, CC3000 and Blynk, following is code which works with a local blynk server .
Hopefully this is formatted correct

Hi.
It looks rather OK…
Did you try http://docs.blynk.cc/#troubleshooting-connection ?
Start with a minimal Blynk CC3000 example :wink:

@vhymanskyy

Thanks, I got it working , was an error on my part in the arduino code it’s fixed now and working

 `     void loop()
      {
  if (!cc3000.checkConnected())           // <========
  Serial.print ("Connected to Server");  //<===
   {
  Blynk.run();
 timer.run();
 }
