10/8/2023 0 Comments Arduino overload serial output![]() SoftwareSerial ESPserial(2, 3) // RX | TX ![]() ![]() At the lower baud rate, I'm not getting any garbage characters. You'll connect the Serial Monitor at 9600. Here's an example script that connects at the default baud rate and then reduces it to 9600. The ESP8266 default baud is 115200, so you need to connect at the default rate and issue an AT command to reduce the baud rate to 9600.Įach time you reset, the ESP8266 goes back to the default baud rate. Using 115200 has too many instructions for the Arduino Uno to reliably decode characters and that's where the garbage is coming from.
