Arduino as serial terminal

eXperiment with Esp8266
Use the arduino as a terminal to check / program the ESP8266
found the soft serial code here: https://www.arduino.cc/en/Tutorial/SoftwareSerialExample
"Works on my machine"
*/
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
void setup() {
Serial.begin(115200);
mySerial.begin(115200); // the ESP8266 I bough on Amazon defaulted to 115,200 baud rate.
}
// the loop function runs over and over again forever
void loop() {
if (mySerial.available()) {
Serial.write(mySerial.read());
}
if (Serial.available()) {
mySerial.write(Serial.read());
}
}
Change and save default baud rate
I want to lower the baud rate because the arduino doesn't keep up with 115200 in the soft serial. I tried to issue the command "AT+UART_DEF=9600,8,1,0,0" to change and SAVE the baud rate but couldn't due to the unreliability of the soft serial at that speed. I was able to change the current baud rate (a shorter string) with "AT+CIOBAUD=9600" Then change baud rate for mySerial in the code, and then write with: "AT+UART_DEF=9600,8,1,0,0" Don't disturb the power while doing this. Then check by disconnecting power and restarting with the terminal set to 9600.
Find some SSIDs
