I am absolutely new to ESP8266.
I am using the ESP device with Arduino UNO.
I understand ESP needs 3.3 V as power supply and also 5 volt from Arduino-TX is controlled by 3x1K resistors to make sure ESP-Rx receives not more than 3 volts, BAUD rate of ESP-Arduino is set at 115200.
I tried different baud rates and took risc of removing 3 resisters (directly connecting Arduino-TX to ESP-RX).
But I always get some garbage message on my serial monitor along with normal message.
Normal message is always not correct...e.g. IPaddress will show as 098.162.15.31 while in reality it is 192.168.15.25, which I have to struggle and find out from cmd>ipaddress etc method....
How can I solve this garbage problem please help....
