I am currently studying WiFi communication using AE-ESP-WROOM-02-DEV.
Your sample program has a very stable connection.
When I run it by specifying the SSID and password of the wireless LAN router on the PC side and the server port as shown below, WiFi connected was displayed.

const char* ssid = “************”;
const char* password = “*************”;
WiFiServer server(23);

00:53:00.786 -> ******************
00:53:01.518 -> ………..
00:53:07.235 -> WiFi connected.
00:53:07.235 -> IP address:
00:53:07.235 -> 192.168.11.4

The next objective is bidirectional signal exchange with the PC side. I would like to experiment with sending a string from the ESP side to the PC side.
I will create client connection software on the PC side using Delphi. In this case, can I connect the HOST to the ESP side using the SSID and password of the wireless LAN router?

Hi.
That’s the normal behavior.
After uploading code you get that message, and you should press the reset button to start running the new code.
Everything seems to be working as expected.
Regards,
Sara

Thank you Sara for your prompt reply.
Of course! after the garbage useful data is coming on serial port.
The garbage comes whenever the Reset button is pressed followed by useful data.
I have set the correct baud rate and all….
The garbage doesn’t appear after programming the IC through USB port in which it finally says
hard reset using CTS. Please clarify
Regards

Hi.
Getting some garbage at first, is normal with the ESP8266.
After that initial garbage, it should print adequately to the serial montior.
Also, make sure that you have the right baud rate selected.

Sara

Hai Rui
In the sketch, I have added Serial.println(“”); but still there is garbage before it prints …. on the serial monitor. Can you tell the command?

Hi David.
I recommend that you take a look at these two tutorials:
