Plugged the power to *what* 3v3 power of the BBB ? I hope you do not mean you hooked the UART of the Arduino to the BBB UART without a logic level converter between the two. I this is the case then there is a chance you've burned out the UART on the BBB that you've hooked to. The Arduino uses 5v serial where the BBB uses 3v3 serial.
Are you using an oscilloscope or a logic Analyzer to check that there is actually UART communications happening ?
