Streaming with ESP8266

$

0

Hello,

 Is it possible to stream data using a ESP8266 Module directly to the API Link?

 

Im using the following code.

#include <ArduinoJson.h>

#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>


 
void setup() {
 
  Serial.begin(115200);                                  //Serial connection
  WiFi.begin("DiAlOg-1", "dialog456@");   //WiFi connection
 
  while (WiFi.status() != WL_CONNECTED) {  //Wait for the WiFI connection completion
 
    delay(500);
    Serial.println("Waiting for connection");
 
  }
 
}
 
void loop() {
 
 if(WiFi.status()== WL_CONNECTED){   //Check WiFi connection status
 
   HTTPClient http;    //Declare object of class HTTPClient
 
   

    const size_t bufferSize = JSON_ARRAY_SIZE(1) + JSON_OBJECT_SIZE(2);
    DynamicJsonBuffer jsonBuffer(bufferSize);
    
    JsonArray& root = jsonBuffer.createArray();
    JsonObject& root_0 = root.createNestedObject();
    root_0["Value1"] = 100;
    root_0["Value2"] = 200;

  
    char JSONmessageBuffer[300];
    root.prettyPrintTo(JSONmessageBuffer, sizeof(JSONmessageBuffer));
    Serial.println(JSONmessageBuffer);

    http.begin("https://api.powerbi.com/beta/852c5799-8134-4f15-9d38-eba4296cc76f/datasets/6014dfc1-93f3-42bb-8ae8-7ec52b051bc8/rows?key=kcW8AI0bvDrT%2BukEOZSFfRxh39HqH0z8hNNPqMqB2PlzlAXvwtw8S9CLCnga3g4tiz2vSonttPDHKfbmNkEUYA%3D%3D");     
    http.addHeader("Content-Type", "application/json");  
 
     int httpCode = http.POST(JSONmessageBuffer);
 
 
   http.end();  //Close connection
 
 }else{
 
    Serial.println("Error in WiFi connection");   
 
 }
 
  delay(1000);  //Send a request every 30 seconds
 
}

And this is the serial Output:

[
  {
    "Value1": 100,
    "Value2": 200
  }
]
[
  {
    "Value1": 100,
    "Value2": 200
  }
]

 

 

It doesn't show any value in the dashboard.. Should this work? What am i doing wrong?

I followed the following tutorial, but instead of the Raspberry Pi, Im using a ESP8266.

Your help is much appreciated. thank you.

 

 

 


couldn't load data for this visual - Gateway Issue

Hi,

 

I have an online report that I'm recently gettting the following error : couldn't load data for this visual -

There is a data source access error. Please contact the gateway administror.

 

image.png

The visual works fine on the Desktop version, so must be down to the Gateway.

The data source is a direct query, that report views from an SQL database.

 

The strange thing is there are other PBI reports working fine, thats off views in the same SQL database and the same gateway.

Any ideas??

 

Thanks

Custom link to report not working (no permission)

$

Hi everyone,

 

Ever since this week I have encountered a problem when publishing a report to the Service. 

 

When I want to set a custom link from an existing dashboard to a newly published report, the text box becomes unclickable. Although there is a link to the report, the link is not active.

 

While existing reports do not seem to be having this problem, new reports seem to be influenced by some sort of bug.

 

Is this a known issue? If so, is there any work-around?

 

Thanks in advance.

Cannot delete Workspace in PowerBI

As an ADMIN, we cannot see the workspace, O365 group or anything associated to it.  The user that created it can still see the app, and it can still be selected in the appstore but is not part of the workspace.

 

Does anyone have insight on how to remove the app for good?

 

 

User Access Limits and Performance Impact

Hi folks,

 

(1) How many users would it take before there were noticeable issues with Power Bi reports using direct query?

(2) Would this be the same when users are accessing the reports via Power Bi Report Server?

(3) Does increasing the spec of Report Server influence performance?

 

Thanks,

Auto change a card background colour depending on text within

Hi Folks,

 

From a Project Management perspective, i want to show the rag status of a project as red, green, amber. Now we have more than one project on the go so as opposed to manually going in and changing the background coulour of all projects, is there any custom visual that can check if status = GREEN, change background colour to green, same for Amber / Red ??

 

I know there is one based on values (Card with states) but not text from what i have seen so far??

 

Any thoughts?

Hi there, 

 

I've connected GA to Power Bi. I'd like to create a chart of my top ten events. I don't see this available as a metric in Power Bi though. Is there something else I need to enable to get the events across or is this not supported?

 

Thanks!

Text heavy VSTS report

Have been asked to pull VSTS data into a text heavy presentation, with columns of categories and subcategories and corresponding rows filtered to the categories.  Its goal is to replace manually creating a Roadmap PPT, and use Power BI pulling from VSTS instead.  There is no visual representation of data, just text.   I'm looking for feedback on whether Power BI is the right tool to be using to display the data.  Any suggestions?

I need the suggestion from this forum , regarding choosing the location of the azure server for the power BI report of our organization. 

 

Most of our users are in South Asia whereas all data sources in Europe. 

 

What is the best practice in this situation in choosing the location of my Power BI Service ? 

 

Should we choose Azure Asia region or Europe region

Restricting Creation of Reports/Dashboards

Hello Community,

 

I would like to setup a Power BI environment which allows the following:

 

  • User A can create reports, dashboards, apps etc
  • User A can share reports, dashboards, apps etc with Users B, C and D (via the Power BI service or another medium which does not expose sensitive data like embed codes do)
  • Users B, C and D cannot create reports, dashbaords, apps etc
  • User A can share different reports with Users B, C and D

Happy to purchases required licences and Office 365 business accounts for this to be possible. I am hoping, however, it does not require a Power BI premium licence.

 

Thank you for your help.

Can't schedule data refresh on Mailchimp report using Mailchimp connector

$

I created a custom report using the Mailchimp Connector (not the Content Pack) and published it to the Power BI service. When I try to schedule a refresh, I get this on the schedule page:

 

You don't have any gateway installed or configured for the data sources in this dataset. Please install a new personal gateway or configure the data source for an existing data gateway.

 

I'm only using 2 data sources for the  report - one is data from our SQL server which is already set up in the data gateway and the other is Mailchimp, which I do not see as set up on the data gateway. I was under the impression that using the connector would automatically configure this.

 

Can anyone give me instructions on what I need to do to add the Mailchimp data source to the gateway?

 

Thanks very much in advance.

Since Friday I'm not able to create a dataset in  app.powerbi.com  for our company EA Azure usage.

 

 

Also tried creating a data source using PowerBI Desktop but the Azure EA source is no longer listed. There's only the beta/development version of insights listed that unfortuantely extracts only December data...

 

We are locked out from our usage data and this is very annoying. Please solve this issue with urgency,

 

Here is the error message for my last tentative:

Hello everyone,

I have small, but really annoying problem. I create report in PowerBi desktop and set format to column with small values to display as decimal (e.g. 0,00000000001) but after publishing it to PowerBi Service it's gose back to scientific format (1,0000000000e-11). Is there any way to change it in PowerBi Service?

Importing reports from one Workspace to another

$

I am having issues when I change a data source from one PBI Workspace to another.  The PBI datasource is the same SSAS service model for both workspaces.

 

Within PBI desktop I chose "Edit Queries" -> "Data Source Settings"

I then browse to the "new" workspace (which has a PBI connection to the same SSAS model as the original workspace, the datasource is named the same as the original)

After chosing the new workspace data source, many of my visualisations report an error (meaningless one!)

If I then save my PBI report, close, then reopen, some of the visulisations seem to be working again, but not all.

 

When I review the visualisations that are still not working, it would seem that the user (creator of the report) has renamed the fields for the visulisation.  Could this be the cause?

 

Any ideas?
