Unable to view Serial Ports (ComPorts) on android

I installed Octo4A on my android phone. It installed Alpine linux and python3. When I run a python script to view the serial ports. It says no ports are found, but it does find the ports on my windows computer using the same script:

import serial.tools.list_ports as ports

def getAvailablePorts():
    availablePorts = list(ports.comports())
    return availablePorts

availablePorts = getAvailablePorts()

for port in availablePorts:
    print("Available port: " + port.device)

The output on windows:

Available port: COM3

Here are the serials listed in Octo4a: enter image description here

How can I get a list of the available ports and connect to it on android using python3?

If you look at the code, the way pyserial looks for ports in Linux is by trying to find the following strings:

/dev/ttyS*     # built-in serial ports
/dev/ttyUSB*   # usb-serial with own driver
/dev/ttyXRUSB* # xr-usb-serial port exar (DELL Edge 3001)
/dev/ttyACM*   # usb-serial with CDC-ACM profile
/dev/ttyAMA*   # ARM internal port (raspi)
/dev/rfcomm*   # BT serial devices
/dev/ttyAP*    # Advantech multi-port serial controllers
/dev/ttyGS*    # https://www.kernel.org/doc/Documentation/usb/gadget_serial.txt

In Octo4A, serial ports are apparently called /dev/ttyOcto4a so they will not be found by list_ports().

Of course, that does not mean pyserial won't work, you can try to instantiate and open your serial port directly with:

import serial

ser = serial.Serial(port='/dev/ttyOcto4a')

ser.isOpen()

I have not tried this myself, so I can not guarantee it will work.
