I hope you are not using pin 0 or 1, those are reserved for USB connection. You must use Software Serial.
Look in the examples section of the EBYTE library for an arduino example.
Note arduinos are 5 volt devices and the pins on the EBYTE are 3.3 but 5 volt tolerant. Yoy may need some series resistors or pullups.
This may help as well
Im using Arduino Uno where the rx is 0 pin and tx is 1 pin. Do you have any sample codes for using Arduino Uno? and sample picture of connection. Thank you!
