Step 1: What Is USB OTG on the Go?

USBcommunication is established between a host(PC for example) and a slave(USB Keyboard or Flash memory).

OTG is a technology that enables you to use USB devices without a PC as a host. That's because OTG devices can work both as a master or a slave USBdevice.

You can find this feature on devices like Smartphones, Cameras, etc.

Xiaomi 5a Smartphone supports OTG technology and hence can be used a slave USB deviceconnected to the PC. And it can also act a host when connected to otherUSB slave devices( USBFlashMemory, Cameras, Keyboard, Mouse)

Step 3: Connect the USB Flash Memory and the USB Keyboard

Connect the USB OTG cable to the phone and then connect the USB Flash Memory.

You can see that The USB FlashMemory is powered from the phone.

Open the file explorer built-in application.

You can see the USB Tab on the application indicating the USBFlashmemory with its contents.

Then switch to another tab on the files explorer. Remove the USB FlashMemory.

Connect the USB Keyboard to theOTG Cable.

Note that popup indicating a physicalUSBkeyboard connected to the phone.

Open word editor. I used Microsoft Word installed on the phone.

Use the USBkeyboard to write on yourphone.
