Communication Arduino Uno <-> Arduino Mega

Projects General Guidance

Hello, I want programming the communication Arduino Uno <-> Arduino Mega.
I know the way is CAN communication, UART communication.
I want easy programming to communication Arduino Uno <-> Arduino Mega. and this way is be free from conflict 'Servo.h', 'SoftwareSerial.h'.

Plz let me know

I2C? There are examples that come with the Wire library that will help get you started.

Which board has the servos? If the Mega has the servos you can use one of the extra hardware serial ports on the Mega and software serial on the Uno.

I has a servo in Mega.
But I use bluetooth in Mega. than I can`t use in Mega software serial.
I want the way, do not use 0 and 1 pin(or I can use Serial monitor in my conputer during communication Arduino Uno <-> Arduino Mega.)

The Mega has 3 extra (aside from Serial on pins 0 and 1) hardware serial ports. Hardware serial will not conflict with the servo library. Use Serial1 for Bluetooth and Serial2 for communicating with the Uno (for instance). You would need to use software serial on the Uno to talk to the Mega and preserve the Uno hardware serial for program upload and debug.
