Call USB OTG by its acronym, but in reality this technology is called USB On-The-Go and sometimes we may read about it as well as USB-host. Be that as it may, it is an extension technology of the USB 2.0 standard, and it is focused on allowing USB devices to have greater capacities of interconnection. A device acts as a host, so that peripherals, USB sticks and accessories of almost all kinds can be connected to it.
El USB OTG It is a really important technology for mobile devices, including both smartphones and tablets. It is what allows them to work with computer peripherals, accessories and devices. And therefore, it reduces dependencies on desktop systems for all types of users. But what is USB OTG really? We explain how this technology works, its key applications and the accessories that we should have around.
From USB OTG as 'extra' to USB Type C with integrated OTG
Indeed, the USB OTG o USB On-The-Go was born as an extension of the USB 2.0 specification; therefore, on devices with such an interface specification, support for OTG had to be checked. That could be available, or not, in such a way that we could not buy any accessory or adapter. Now, however, the specification USB 3.1, with the USB Type C, integrates this feature 'by default'. It means that it is no longer necessary to use any type of adapter or special connector, or to check the compatibility of accessories.
How does USB OTG work on mobile devices?
USB standards, in specifications USB 1.1 to USB 2.0 use an architecture of master and slave; that is, the USB hub works as a master, while another device works as a slave to the previous one. Only devices that work as a USB hub or USB hub can manage settings and data transfers in the interconnection between devices. Thanks to USB OTGHowever, this guideline is changed and compatible devices have the ability to open a session exchange, control the connection and exchange the functions of teacher.
The USB OTG extension, or USB On-The-Go, introduces the protocols SRP and HNP. The first is the session request protocol, while the second is the host negotiation protocol. Compatibility is limited to the 1.1 and USB 2.0 specifications, and the behavior is normal when not connecting with a USB OTG device. Therefore, although we have USB OTG we can use our connector in a normal way, in addition to the physical connection is exactly the same.
What is USB OTG for on mobile devices (and tablets) with Android operating system?
The applications of the USB OTG they are really spacious. The key is that you have the ability to send data without the need for a master USB controller, which is a unique feature of desktop computers. Thus, for example, a camera can send its images directly to a printer, or access a hard disk. In the case of Android mobile devices, it is what allows you to connect keyboards, memories, USB modems and other accessories and peripherals.
Thanks to this technology, to our Android smartphone or tablet we can connect a card reader of all kinds, or a printer, or accessories and peripherals. This will allow us to play more comfortably with a wired controller, for example, or turn our device into a complete computer. In fact, the intention behind this technology is to reduce the dependencies of the smartphone in front of the desktop computer. We can also connect hard drives and other portable storage media.
