How to connect Espduino to blynk?

Need Help With My Project
1

Hello, i got the ESPDuino Development Board ESP-13

What to choose ? Esp8266_standalone or esp8266 Shield?

Thanks for help

Set for Arduino UNO with WiFi in the App, program as if Arduino UNO with an ESP as shield.

So do i need to send the AT Commands to the board before?

when i try to compile the example sketch you gave me i get.

You do need to read through the sketch and make changes according to hardware and how your ESP is wired to the Arduino… Serial1 is a specific port for specific hardware (Hint - not the UNO).

I don’t know enough about your board, but the ESP is probably connected via some particular IO pin and probably uses SoftwareSerial… or perhaps it uses some internal switching and shares the primary USP/Serial port, in which you might use Serial.

Read up on whatever documentation you have for that board and it’s interface between the UNO and the ESP and use the same connection references in the Blynk sketch.

Based on this Bangood reference… perhaps try treating it as a basic ESP8266 and see how that works.

Set your App for ESP8266 (generic)
