Blynk app problems

I have installed the app but have no dashboard or anything but limited widget’s also I get an error message that says your Arduino Yun is not…and then no more information than that

Please follow the common rules, described here:

Your topic has no category, it means that it’s unlikely that someone will help.

Also, Blynk is not Blink :wink: please

Should “Blynk is not ideal. Yet.” read “Blynk is not perfect. Yet.”?

Firstly let me apologise to you for my rather abrupt tone, frustration!
I am very new to this but your product and community is very exiting indeed and will get up to speed on forum etiquette. My project is simple I am using an AD595 Thermocouple Amp and need a temp range of ambient to 650’C its for an oven.
I want to replace my multimeter with my Android phone.
I am not sure that I have downloaded the app correctly as I don’t seem to have all the features, again this is probably me. What I am looking for is a solution to this as I tend to learn quicker if I see a solution and can spend time to totally understand then move on, however I don’t want to be spoon fed as this is not the way to learn.
It’s been 30 years since I wrote any code this was with a BBC Micro, we didn’t have WIFI back then! that was the preserve of guy’s whose last name was Kirk. if you would lead me my the hand with this I would be grateful.
Here is the simple piece of code I am using, I would just like to add that my data fluctuates a lot but working on the Arduino Yun forum to sort that. I did mention I have a Yun and a Particle Core as my project choices.
Thanks for your patience

float temp ;

 void setup(){

Serial.begin(9600);
}
 void loop()
{

int raw = analogRead(A0);

float Vout = raw * (5 / 1023.0);

temp = (Vout) / 0.01;

Serial.println(temp);

delay(500);
}

Your project can be very easily accomplished with Blynk. And we would be very eager to help

The best flow is next:

  1. Make it work without Blynk. If you are able to get temp reading to the serial monitor - that’s 95% of success
  2. Did you check our getting started section? After you install the Blynk library - check example for Yùn. Just upload it to the board (don’t forget the Auth Token), connect an LED and try to control it with Blynk app.

Let us know if you have succeeded with these steps and we’ll move further.

Is it solved? What do you mean no dashboard? Where are you getting the message then?

Which OS are you using?

hi
Today I have made progress my simple code now gives good data to serial monitor.
After re-reading (carefully this time!) I believe I have installed the library’s correctly Bridge and Blynk are there. Also the app does not complain that there is no internet so I must have got some thing else right. However when I compile your example I get an error which I have used the IDE “copy error messages” function and will paste at the end for you.
My Android software is V4.4.3 and I am using Windows 10
Error’s:-
Arduino: 1.6.5 (Windows 8.1), Board: “Arduino Yún”

test2:1: error: stray ‘#’ in program
test2:2: error: stray ‘#’ in program
test2:3: error: stray ‘#’ in program
test2:1: error: expected unqualified-id before numeric constant
test2:9: error: expected unqualified-id before numeric constant
test2:19: error: expected unqualified-id before numeric constant
stray ‘#’ in program

This report would have more information with
“Show verbose output during compilation”
enabled in File > Preferences.
I look forward to hearing your thoughts
Andy

It’s really hard to say what’s happening without seeing your code.

Also, did you follow my instructions? Step 1, Step 2 ? :wink:

HI
The previous reply said that I have got data to the serial monitor and I believe the library’s are installed correctly the code is the example that you gave me in an e- mail with the addition of the “Authorisation Code” step 1,2 I am worried that my reply did not get to you because I am doing something wrong but one thing I forgot to mention is that if you look at the previous reply the error message states windows 8.1 have I got the correct IDE?
Andy

Please post your code.
Arduino IDE version is good.

Did you try to upload an initial Blynk Yun example sketch to your Arduino?

hi
After installation of library’s I then went to your suggested example page that took me to GitHub from there I copied and pasted the code to my Arduino IDE. I then logged on to the Blynk App and e-mailed a fresh authorisation code to myself which I then pasted to the code, then attempted to compile it and received the error message.
Here’s the code:-

hope this is the format you need still getting used to it all and hope you can see where I’m going wrong
Hi I am editing this as I have now compiled the code above successfully and the serial monitor displays:-
[3050064] connecting to cloud.blynk.cc:8442
I now set a simple button to pin(9) press play and then press the button which lights up on the phone but the bottom of the display reads “you Arduino Yun is not in…”
can you help me over the line

Thanks
Andy
