Hello everyone. I'm using ESP8266 NodeMCU LUA CP2102 ESP-12E Internet WIFI Development Board which bought from https://www.amazon.com/HiLetgo-Version-NodeMCU-Internet-Development/dp/B010O1G1ES/ref=cm_cr_arp_d_product_top?ie=UTF8
I want to use the ESP-12E to connect with my Arduino Robot https://www.arduino.cc/en/Guide/Robot which will receive signals from node-red and send the received signal to the Arduino Robot. I plan to do this using MQTT and Arduino Ide. So the question is do I need to flash the ESP-12E with any firmware or I can directly use it in the project? Besides, can anyone tell me how to change the baud rate of the ESP-12E to 9600? Is the Serial.begin() command in the Arduino Ide will help to set the baud rate to 9600?
