How do I set up UART communication between BeagleBone Black and Esp32?

Hello, I’m working on a light intensity monitoring system using BeagleBone Black and a Esp32. How do I set up UART communication between BeagleBone Black and Esp32? Because am receiving no data from microcontroller, I have checked checked UART pin connections and baud rate settings.

     # BeagleBone Black Python code
     import serial
     ser = serial.Serial('/dev/ttyO1', 9600)
     while True:
         if ser.in_waiting > 0:
             light_level = ser.readline().decode('utf-8').strip()
             print(f"Light Level: {light_level}")

     # BeagleBone Black Python code
     import serial
     ser = serial.Serial('/dev/ttyO1', 9600)
     while True:
         if ser.in_waiting > 0:
             light_level = ser.readline().decode('utf-8').strip()
             print(f"Light Level: {light_level}")
