Hello there,
I’m pretty new to all kind of hardware programming, but I wanted to try something. So I decided to buy an Andruino UNO and an ESP8266. I followed many of the tutorials you can find on the internet and connected the modules as explained. Everything starts up and seems to be working. But as soon as I send some AT commands via serial monitor, my ESP responding with non readable Text.
So I configurated my softwareserial with all kinds of baud rates but none of it worked. At least 115200 provides some readable content. I attached a screenshot of my serial monitor.
Here is the code I’m using to send AT commands.
/*
Software serial multple serial test
Receives from the hardware serial, sends to software serial.
Receives from software serial, sends to hardware serial.
The circuit:
* RX is digital pin 10 (connect to TX of other device)
* TX is digital pin 11 (connect to RX of other device)
Note:
Not all pins on the Mega and Mega 2560 support change interrupts,
so only the following can be used for RX:
10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
Not all pins on the Leonardo support change interrupts,
so only the following can be used for RX:
8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).

This example code is in the public domain.

#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Goodnight moon!");
// set the data rate for the SoftwareSerial port
mySerial.begin(115200);
}
void loop() { // run over and over
if (mySerial.available()) {
Serial.write(mySerial.read());
}
if (Serial.available()) {
mySerial.write(Serial.read());
}
}
It seems the ESP reacts to my commands but the response is just rubish.
Could you pleas let me know what I can do?
Regards,
Michael
