Could you help me please.
Then probably the baud rate is wrong. The standard baud rate in ESP32 environments is 115200. Did you use
monitor_speed = 115200 in the
You are not supposed to create an object of that one. In Arduino you have the
Serial object globally available, which is an instance of
HardwareSerial, which implements the
Print interface. See the documentation. Using
std::cout instead of
Serial in Arduino firmwares is quite unusual.
