Does WirelessUSB exist?

Wed Feb 05, 2014 1:42 pm

I want 2 wirelessly connect a computer USB port and say an Arduino USB port.

BUT....
I don't want to have to install any software at either end - I just want a transparent USB wireless link.

Do they exist at all and are there any <£50?

Hi Simon,

USB is more complex than a plane RS-232, for example. There are several USB profiles (HID, MSD, CDC,...) and this should be your starting point. Also be aware that the peers are not equal, one is always master and the other is slave.

If you describe some details about your requirement, I can probably give you better answer...

How do you expect the Arduino board to be visible by the Computer ? As a serial port, sound card, hard disk, MIDI device, keyboard, ... ?

Lets keep it simple - upload a blinkpin13 sketch :)

Wireless USB certainly exists as a tentative 'standard', and has done for some time...

http://www.everythingusb.com/wireless-usb.html

http://arstechnica.com/information-tech ... bit-speed/

But it's not clear there are any actual products on the market.

Quoting the second source, as of Sept 2013 -
As is typical, working on the spec and getting the technology into shipping products will take a while. "We anticipate that the MA USB specification will be completed within the next year," USB-IF said. "It will likely be another 8-12 months after that before we actually see the technology in consumer devices on retail shelves."

LadyAda has this sussed using her Bluetooth serial link device. Looks like a nice bit of kit, does DTR/RTS/DSR and dynamic baud rate selection. I've got one in the mail, I'll let you know how it works out.

Hi,

You'd need to convert USB to "something wireless" and then back to USB. USB timing requirements are very strict, what is the main reason that you cannot insert general wireless transparent channel. Therefore, I don't see any viable solution here which would not be dedicated and limited to just predefined set of use cases (forget about "one size fits all").
I believe that this is the reason why we cannot find these products around in the mainstream category ruled by three things only: quantity, quantity and quantity.

Saw the bluetooth dongle, very neat. Note if you just want wireless debug then a normal serial bluetooth module will work nicely (but for programming the additional signals are needed).

One solution for wireless USB is using USB over network, I think there is one which is supported on the RPi, although I've never tried it. That would need to be PI to PI.

We should be aware that it is not a kind of upgrade or add-on to the wired USB.
I see it similarly as Ethernet network versus WiFi - different species.

Well there are usb extenders via ethernet:

(the "usb network server" types, not the ones that just use rj45/cat5 cable)

So add wifi bridge in between...may work.


Real "wireless usb" was beaten to market by cheap wifi and bluetooth:

[edit]
though I've just read belkin actually made a product and you can buy it here:
http://www.amazon.co.uk/Belkin-CERT-WUS ... B00166VB1E for £40 !
it does need software on the PC end.

so in summary
No :)

Just wanted to check if transparent working wireless USB existed at a reasonable price.

Engineers NEVER say no. They just say it will cost you more and take longer.

Also, wireless USB is a solution looking for a problem. One that is effectively cornered by bluetooth for low bandwidth and normal 802.11 wireless for high bandwidth.

But wirelessly connecting an arduino to a computer in a simple, hassle free way is a problem looking for a solution :0)
Lot's of chatter about it in arduino forums as well.

No :)

It was wireless, driverless, platform/OS aggnostic solution I was looking for - not niche :)

The equivalent of replacing a wired telegraph with a wireless one but keeping the same key at both ends so that the operator doesn't notice the difference :)

The bluetooth solution would work, only difference would be programming over serial port rather than USB.

(I think) In general, a direct, hardware, USB data to Bluetooth (and vice versa) converter would be ace, think of all those wires you could cut out, but given that USB is so blisteringly fast, could Bluetooth cope with it?
