Wifi Controlled USB Mouse and Keyboard (ESP8285)

NOTE: Only the raw chips are available on ebay right now...
Using espusb, now I can emulate a USB mouse+keyboard able to hook up to any computer in the USB port. It functions as a normal USB HID keyboard+mouse so it doesn't need drivers. It run on an ESP8285, the ESP8266's integrated-flash cousin.

Hi Charles, I am using your ESPUSB project to create a WiFi connected keyboard (instead of Bluetooth). But I am having trouble setting up the ESP as a websocket client (the keyboard). Could you point me to a good C implementation of websocket client or is it already implemented in the API you created and I am just too stupid to find it? Any help would be much appreciated!!!

Where can I see a list of commands for controlling the keyboard and mouse. Using the web interface is not very convenient.

[@CNLohr]

You'll have to go through the source for that. I never really polished any of the interfaces.

[@himselfe]

I've been toying with similar ideas for a while, but in a slightly reversed way to this. It would be nice to be able to plug USB devices into the ESP and have it as a sort of USB server for the network that lets you share USB devices such as a keyboard and mouse between various computers. Personally I would opt for hardware USB by mating the ESP with a dedicated host mode driver (or micro-controller with hardware support for host mode USB). My thoughts have somewhat diverged from the initial idea recently however. Such a setup would require specific drivers for each OS, which isn't ideal. Now my interest lies in creating a bridge device that allows multiple computers to be plugged into one hub, and devices into another, and bridge the communication in such a way that devices can be arbitrarily assigned to or switched between different computers. Thinking about it, perhaps an interesting extension of your project would be to use a second ESP as a host to USB devices, and have it pass USB packets OTA to one or more of these ESPUSB dongles? A Combination of this current dongle, and a host mode dongle based on the ESP could open up a world of possibilities!

[@CNLohr]

I think it would be neat to support USB OTG/Host, but, until I have a specific need, I don't intend to go down that path, since it would be a fair bit of thinking and writing a host driver. At low speed, it wouldn't be very difficult, though.

[@himselfe]

That figures. Although thinking about the specific use case I mentioned, it would in theory be possible to use the ESPs as a bridge/passthrough that simply passes the USB packets with minimal actual processing on the ESPs beyond what is needed to establish the connections.

[@CNLohr]

The problem is more with the standard rather than the ESP. You would have to be very creative about your endpoint usage. USB expects responses to be returned 6.5 bit slices after the end of the host's request. Timing is absolutely critical. You would have to, at a high level, read from the USB keyboard/mouse.

[@himselfe]

I guess that would require emulation rather than a simple pass through then. Ideally it would be better to use a hardware USB controller, but I think I remember from the part of your live feed recording I watched (about 3 of the 6 hours :P) that you said you weren't interested in using an external micro controller for the USB part?

[@CNLohr]

You could still emulate low-speed devices, like mouse/keyboard.. But you are correct. I am strictly interested in doing everything on-board.

[@TheRealKitWalker]

CNLohr I'm trying to use it as serial over wifi transceiver, to universally flash other boards that are not connected on OTA, or like when you need to flash a DD-WRT on a router over the air. That needs TX, RX, DTR & Reset Pins. Just heard a Yield() is to save ESP from panic, and there is a library that save panic log on it and you can read it from serial connection easily. (streaming data will crash it) Any links you know might be useful for please? I read but not that advanced yet. Im using Arduino DUE, its way advanced than esp, and act as a keyboard and mouse. I used it when i was traveling, to test a ras-pi, needed keyboard so i used due. Sorry I wrote alot.

[@CNLohr]

Well, I assure you an ESP has a lot more horsepower and sophistication than an Arduino Due. But, if I were you I would not use the arduino environment. It will probably get in your way. The C environment can sustain some serious speeds and handle rapid interrupt handling from things like serial.

Get some extra flux, solder wick, add some extra solder, use a fine-point soldering iron and glob a little more on, then use the soldering iron to start to wick some away.

forgive my noviciate level, I’m only just getting started with Arduino in general - Cos I wanna build an idea and has led me here… Please, let me ask my question as I would speak: I see that the ESP8285 together with the esp82xx library are allowing you to program the module talk over WiFi to your phone using the GUI you (or good fellows) have designed and coded out… & I believe, I think this is correct - Along with the esp82xx libs(?) the module actually achieves this by tapping into (or borrowing from?) /using the computers own inbuilt Wifi hardware and drivers?? Thus, to my understanding (if I’ve been so far correct) This solution (espusb) is and can be used to turn (my) “whole entire computer” effectively into one (rather oversized) Wireless USB Transceiver/Dongle/Stick/Adaptor… That is, at least to a cell phone running a small HID GUI Application to communicate, exchange input data with and well, function… SO… If I wanted to have it interface with something not so “smart” as a Cell phone…. Something like a wireless mouse I’ve long ago misplaced the usb adaptor for…. ( **this is where my knowledge begins to end, some of my terminologies may be incorrect or confused so I’ll talk more colloquially from now on - FYI**. ) Let’s pretend I had Wireless Razer Mouse for example. I imagine that instead of “pointing” the code to detect the “mouse” (the ESP8285 plugged into a USB slot on the PC) and rather than “default” to Sys32(?) Network drivers - have it “choose” or prompt user (I guess…) for a selection…. MsgBox:: “Initiating ESP8285. Press 1 for Windows Wifi or 2 for Razer Mouse connection” *presses 2*. ….. Error…. I haven't got installed the firmware for - No, or written the code-between for - Or, really don’t even know if I can find source code for something like a Razer mouse …… I would imagine one probably can not as it would have to be all very proprietary. At least in the registry communications pages… I realise I haven’t really asked a question so much as simply for a bit of info - I know you can’t expressly talk about “Razer” - you may very well have zero experience of their products at all - Please, be advised I use that particular Brand as an example only and you can imagine it to be any one of a great many other manufacturers of wireless HID devices you like, might, could or can! :) …You get what I mean and what I’m asking, right?

CNLohr isn't building it, but it will be available from me! I'll take pre-orders from now until the end of the year, and then get PCBWay to make another batch.

@@peterburkimsher6080 I need one, how much is it?

[@peterburkimsher6080]

@@goata007 The project was on hold the last few months; FCC certifications made it impossible. Email [e-mail] to talk about how to order small quantities for personal use!

Can it pretend to be a webcam?

Its like a diy inputstick

This can be done using just an app and no hardware just phone and pc. Probably loads viruses on your pc though...

unified remote on playstore is awesome

Never mind, I found the gerber files.

I think they tried to do that with a MacBook,

Check out pcbs.io/ for boards. Their default is 1.2mm as opposed to the OSH Park 1.6mm default. Pricing is similarly awesome for small boards.

[@CNLohr]

Neat, I will consider that in the future.

[@peterburkimsher6080]

Any plans for manufacturing and selling a batch of the boards? I seriously want to buy one of these. It would seriously improve my life in the server room.

[@CNLohr]

I am seriously thinking about it. I have two more designs coming in. I want to see how good they are. If they work out I could totally do it.

Wow. Impressing :-)

watched it on 14 feb 2022, instead of hangout with gf.

[@CNLohr]

y not both?

[@tohopes]

Damn, I was impressed until you said it wasn't a Full-Speed keyboard. I don't need no 28.8 bps modem slowing down my typing on the internets.

[@CNLohr]

o.O it's 1.5 MBits/sec.

[@aerobyrdable]

can you give us noobs some context as to what one can and can't do with 1.5Mb/s, please?

[@CNLohr]

HID devices, things like joysticks, MIDI, keyboard/mouse, etc. AND Control Messages. Which allow you to send well-formatted messages to-and-from the device without having to worry about the mess of framing, CRC, types, etc... associated with serial streams.

[@CNLohr]

Can't: Bulk devices (Mass-stroage, network adapter)

[@tohopes]

I guesstimate that low-bit-rate audio devices would be just doable, but not high-bit-rate ones.
