ardiuno serial communication usb cable direction importance

Projects General Guidance

I am trying establish serial communication between my tablet and arduino nano. I found that the direction of the cable Im using is importent:

while using adapter from usb to usb micro I wanted to be able to connect the adatper like so:

1200×1600 42.1 KB

so I would be able to plug in any cable (of any kind) and communicate with the arduino.

While trying to do so I found out that when the cable is with the usb side connected (with the adapter) to the arduino the arduino doesnt have power and I can not communicate with it:

1600×1200 57.5 KB

and when I switched the direction of the cable (the adapter side connected to the tablet) the arduino gets power and I can communicate with it:

1600×1200 57.8 KB

*I tried with my phone (with usb C connection) and I came with the same result so I dont think that the problem is the power supply.

If any one know why is it happening or if there is any way that I would be able to have usb female exit in the arduino side?

It is not the cable, but the adapter which is a "USB OTG adapter" (OnTheGo), and will only work when connected to a phone or tablet.

A USB host (typically a PC) can control a USB device (keyboard, disk, Arduino....).

A tablet or a phone is normally a USB Device and presents itself as a "USB Mass Storage Device" when connected to a USB host.

By using a USB OTG adapter, the phone or tablet can act as a host, and connect to devices like the Arduino.
The Arduino can only be a device.
