• ESP8266 with NodeMCU 1.0 (ESP-12F).
• Smartphone Android
• Blynk server
• Blynk Library version 1.0.1
I encountered some problems when learning how to use templates to connect the ESP8266 to my smart phone app. I use the sample of blynk.Edgent_ESP8266 in Arduino IDE, that is part of my code.
// Fill-in information from your Blynk Template here
#define BLYNK_TEMPLATE_ID "TMPL5_FF_0-F"
#define BLYNK_DEVICE_NAME "Quickstart Template"
#define BLYNK_FIRMWARE_VERSION "0.1.0"
#define BLYNK_PRINT Serial
//#define BLYNK_DEBUG
#define APP_DEBUG
// Uncomment your board, or configure a custom board in Settings.h
//#define USE_SPARKFUN_BLYNK_BOARD
//#define USE_NODE_MCU_BOARD
//#define USE_WITTY_CLOUD_BOARD
#include "BlynkEdgent.h"
void setup()
{
Serial.begin(115200);
delay(100);
BlynkEdgent.begin();
}
void loop() {
BlynkEdgent.run();
}
and the result in Serial is above.

I checked my template ID carefully and I don’t know what happen.
The another question is that my APP is sometimes similar to the Cloud (two device) and sometimes different (one device named quickstart Device), that’s my screenshot, I want to know what happened.
Have you copied and pasted the template ID and device name from the web console into your sketch?
I’m a bit confused by the fact that you’re using QuickStart (which uses static provisioning of Auth tokens and WiFi credentials) with the Edgent sketch - which uses dynamic provisioning.
You would be far better deleting the QuickStart template via the web console, creating a template and adding the datastreams you want, then pasting the template ID and device name into your sketch and going from there.
Also, you really need to un-comment a board type and check that the pins in Settings.h correspond exactly to your board. You should read this for more info on that subject…
It worked like you said it would, and it still wrong, so I tried to use the QuickStart template that connected successfully to my console and APP to run my code. As before, this still not work.
I have copied and pasted them, but it still wrong. Then I tried to constructed different template and copy their ID and name, that my new code.

I think my copy is correct.
It is strange that I can use the QuickStart code to connected my console and APP and device, the code is:
// Template ID, Device Name and Auth Token are provided by the Blynk.Cloud
// See the Device Info tab, or Template settings
#define BLYNK_TEMPLATE_ID "TMPLSwkvn-Vx"
#define BLYNK_DEVICE_NAME "LED Blink"
#define BLYNK_AUTH_TOKEN "C3QGEgoZkYNXvyExjcz5hQiyqcY0FwCM"
// Comment this out to disable prints and save space
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = BLYNK_AUTH_TOKEN;
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "qsf2902";
char pass[] = "29022902";
BlynkTimer timer;
// This function is called every time the Virtual Pin 0 state changes
BLYNK_WRITE(V0)
{
// Set incoming value from pin V0 to a variable
int value = param.asInt();
if(value==1){
digitalWrite(D2,HIGH);
}
else{
digitalWrite(D2,LOW);
}
// Update state
Blynk.virtualWrite(V1, value);
}
// This function is called every time the device is connected to the Blynk.Cloud
BLYNK_CONNECTED()
{
Blynk.syncVirtual(V0);
// Change Web Link Button message to "Congratulations!"
Blynk.setProperty(V3, "offImageUrl", "https://static-image.nyc3.cdn.digitaloceanspaces.com/general/fte/congratulations.png");
Blynk.setProperty(V3, "onImageUrl", "https://static-image.nyc3.cdn.digitaloceanspaces.com/general/fte/congratulations_pressed.png");
Blynk.setProperty(V3, "url", "https://docs.blynk.io/en/getting-started/what-do-i-need-to-blynk/how-quickstart-device-was-made");
}
// This function sends Arduino's uptime every second to Virtual Pin 2.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V2, millis() / 1000);
}
void setup()
{
pinMode(D2,OUTPUT);
// Debug console
Serial.begin(115200);
delay(100);
Blynk.begin(auth, ssid, pass,"blynk.cloud", 80);
// You can also specify server:
//Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);
//Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
// Setup a function to be called every second
timer.setInterval(1000L, myTimerEvent);
}
void loop()
{
Blynk.run();
timer.run();
// You can inject your own code or combine it with other sketches.
// Check other examples on how to communicate with Blynk. Remember
// to avoid delay() function!
}
And I can use it to light my LED by APP, I think there is something wrong in the process of validating the template id.
There is no point dumping lots of code into your replies if you aren’t going to include screenshots of your template setup in the web console as well.
The problem with mixing and matching static QuickStart examples with dynamic Edgent examples is that QuickStart creates the device for you, and with Edgent you add the device when you do the provisioning.
Stick to one method or another, don’t mix them up.
I’m sorry about my unclear description. That’s means that I referred to your teachings and the Edgent related links, and I operated following the instructions, but it still mistake about my template id, even though I deleted the QuickStart template and created a new template.
In my next attempt, I just use the template to create a device by console and use some code like this to connect my device and it can work well both in console and APP.
This is the same template id I had before I created the device, but it now takes effect.
That’s a good suggestion and I will using my successful method to operate and make some project.
Thank you again for your reply in your busy schedule.
