Hi there! First of all: I tried 4 hours of searching the internet but still can’t solve my problem, maybe your knowlegde will help me, so here it is:
I bought an WeMos ATmega2560+ESP8266 Board, it has an integrated ESP8266 and the connection is controlled via DIP-switches. I want to do a simple Blynk project, where I can controle an LED via the APP. For the most part I’ve followed the instructions in this YouTube Video, where a stand alone ESP is used (https://www.youtube.com/watch?v=YLKEZtLhfZo&t=2137s). However working with the WeMos was fine, I did the following steps:
Flash a new AT command firmware version 1.5.4 (AiThinker_ESP8266_DIO_8M_8M_20160615_V1.5.4) onto the ESP8266
Set up the Blynk sketch from the Website with the following settings: Board - Arduino Mega 2560, Connection - ESP8266 WiFi Shield, the Auth Token, Example - Push Data (all I changed in the C code is the SSID and Password of the network)
Uploaded the sketch to the Arduino and opended the serial monitor to see if things are working well
The Problem is, that the connection to the ESP isn’t correctly established. All I’m getting is:

[1609] ESP is not responding
Thanks for your help anyway, because I’ve never seen any other board than this one :'D But yeah I do think so, I’ve set the DIP switches so that I can access the ESP directly and typed AT to see if everything is working, it returned OK, and AT+GMR returns the current infos about the device, so this should be alright

// You should get Auth Token in the Blynk App.

ESP8266 wifi(&EspSerial);
BlynkTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V5, millis() / 1000);
}
void setup()
{
// Debug console
Serial.begin(9600);
// Set ESP8266 baud rate
EspSerial.begin(ESP8266_BAUD);
delay(10);
Blynk.begin(auth, wifi, ssid, pass);
// You can also specify server:
//Blynk.begin(auth, wifi, ssid, pass, "blynk-cloud.com", 80);
//Blynk.begin(auth, wifi, 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(); // Initiates BlynkTimer
}
Valid argument, here is the code I use. The Baudrate is set to 115200 where most AT drivers communicate as far as I know and when I connect to the ESP via DIP-switches, 115200 is the correct Baudrate for the Serial Monitor, which is also set in the sketch. Sending commands directly to the ESP works fine. But the communcation between the Mega and the ESP doesn’t
Thanks Pete! I was overlooking that line of code
Now it successfully connects to the WiFi
But one more thing to go: there is no ping reaction from the Blynk Cloud, so the APP is still saying the project wasn’t online yet. May this has to do with my Firewall settings or something like that? Cause my Auth Token is the one I got per E-Mail, checked it twice. And btw I tried pinging the www.blynk-cloud.com and that works fine, but here it stucks:

I don’t think so. I also tried multiple way for connecting, directly via the vodafone router, via my Laptop hotspot and via a mobile hotspot from my phone which has E-Plus as provider. It always stucks after connecting. No timeout or something, just stuck. I’m wondering if it has anything to do with that Connect Wifi message at the beginning

It shows CONNECTED when using the mobile hotspot, DISCONNECTED when using the router

My knowledge about the whole IP thing isn’t top notch
