Hello guys I have my ESP8266 connected to my Arduino. Then I typed in AT in the serial monitor. It confirmed this command with OK. After that I typed in AT+UART=9600, 8, 1, 0, 0 which gave me the response ERROR. Then I googled what I could do, which told me that I should try change the baud rate permanently with the command AT+IPR=9600. I did this but I got no response. After that I wondered if everything was ok so I typed in AT. No response. Now I'm a little bit sad because everything started to be great but I don't know how I can fix the whole problem. I also tried to upgrade its firmware with XTCOM Utility but it says it can't connect.
#include <SoftwareSerial.h>
SoftwareSerial ESPserial(2, 3); // RX | TX
void setup() {
Serial.begin(115200); // communication with the host computer
//while (!Serial) { ; }
// Start the software serial for communication with the ESP8266
ESPserial.begin(115200);
Serial.println("");
Serial.println("Remember to to set Both NL & CR in the serial monitor.");
Serial.println("Ready");
Serial.println("");
}
void loop() {
// listen for communication from the ESP8266 and then write it to the serial monitor
if ( ESPserial.available() ) { Serial.write( ESPserial.read() ); }
// listen for user input and send it to the ESP8266
if ( Serial.available() ) { ESPserial.write( Serial.read() ); }
}
This is my code. I tried it with both 9600 and 115200 but if I use 115200 the serial monitor just shows some garbage signs. It's kind of frustrating because I can't even interact with the serial monitor as my typed commands don't show up anymore. Do you have any idea how I could fix this problem?
EDIT:
I read that the command AT+IPR=9600 breaks the module and it can just be fixed by reflashing it. Sadly this doesn't work because it somehow can`t connect.
