I'm working to develop an application to use a rooted Nook STR as a handheld data input platform, which then sends the data to another Android device (tablet or phone; TBD) acting as a hub. From what I've been able to determine, the options for communications between the devices are:
Bluetooth
-Possibly available using a dongle, USB OTG cable, and enabling USB host mode as described here. This doesn't seem practical within the time/budget/scale of our application.
Wi-Fi
-Wi-Fi Direct would be ideal, but requires either Android 4.x or a patch/hack to enable it, which I haven't seen anyone working on (correct me if I'm wrong about this)
-Separate Wi-Fi hub to manage communications between the devices
Is there an alternative, implementable within reasonable time and cost, to facilitate device-to-device communications wirelessly and without additional separate hardware? My research hasn't turned up any solutions that aren't extremely awkward, but I'm relatively new to this, so hopefully someone has a better idea or knows of an obvious possibility that I'm missing.

Connecting Keyboard Like Devices via USB or Bluetooth To Mogul
I have searched through the posts here and in other forums and have not found a precise or complete answer to these questions. Any help would be appreciated. I'm not an expert. I did read one post about using the Mogul as a control device ( keyboard ) however a very useful application is to use the Mogul as a data collection device in the field, especially when end users may have devices all ready connecting to laptops/desktops via the USB and seen as ASCII output ( like a 101 keyboard ).
Does the Mogul have USB host capability through the connector? There seems to be conflicting opinions. If it does what is needed to turn on the capability?
This is the scenario I am trying create without having to rebuild or build new devices. A cost effective solution is the goal.
Assume the data collection devices I want to connect to the Mogul have a standard USB connector and wiring the same as a USB 101 type keyboard ( though the devices are not keyboards ) and the signals coming out of the connector are the same. The data stream is ASCII character stream. The USB devices are self powered so they do not need to draw the 5 volts from the Mogul.
The goal is to connect such a device to the Mogul directly via the USB connector so that it looks like a keyboard OR connect the device to an external Bluetooth transmitter that looks like a Bluetooth keyboard.
Off the self product would be preferable to having to black box the project.
It would seem simple considering there are USB Bluetooth transmitters at fairly low cost, but I have not been able to find one for this specific application. Hacking and existing Bluetooth keyboard might work but it would be a bulky solution, a considerable downside as well as expense for each of the devices.
I'm not a corporate Mogul, just a single employee end user who has specific data collection needs.
Thanks in advance
It was suggested in the Titan forum on another subject that this type of discussion would be more appropriate and fruitful in the developer area.
I have just enough knowledge and experience to be dangerous with a soldering iron and electronic parts.

Hy everyone,
First of all, thanks for this great forum which never fails to impress me.
I have a question which some of you might help answering: I'm wondering if it's possible to use the mini-usb port of my smartphone to get some data input.
Let me explain myself a bit more: I know that smartphones (HTC Touch for me) aren't USB hosts. However, the data connexions are still present.
Here's what I'd like to do: even though the smartphone can't control another peripheral, I'd like that external peripheral to send data to the smartphone, and the smartphone to use that data to control the screen. That would give an alternative way of controlling the screen.
The input would come from another touch surface, so my guess is that using the data to control the screen shouldn't be much of a problem.
So? Any idea if it's possible? What kind of platform/language would be nice to do that? C#?
(I have JAVA development experience, but I'm quite a newbie as far as Win Mobile devs are concerned. I'm willing to learn though
I think I searched this forum (and others) quite extensively before posting. If by any chance I missed a related post, I'd be glad to know about it
No ideas? Anyone?
Last up before I stop...
prob. not
i dont think that is technically possible. i think one has to be the host, and that host provides power. so to power the input device(im thinking keyboard) it would need the smartphone/ppc to be a host....
but i have no clue in this area...maybe someone could prove me wrong?
Hey, thanks for your answer.
The powering issues could be overcomed by cutting the cables and giving power from an external power source (I think several people have tried doing it, I need to find the links again). By the way, the peripheral itself is plugged on 110V, so there's plenty of available power
I'm not seeking here to "control" the device, just to aquire the signal it's sending... Does that seem feasible, or does the peripheral need to be somehow "activated" by a Host before sending anything?
Well, in order to get data, the host must ask the slave each time it needs some. Other things must be done by the host, like usb enumeration. That means there has to be a host or it won't work, unless you use usb on-the-go, but I do not know many devices that support it.
according to the qualcomm website, the msm chipsets support otg
Hi..
I am planning on starting a project to develop my idea of a PSD.
Essentially the primary goal is to bring many benefits of cloud storage, offline but always available in your pocket.
It will be a light weight, battery and USB powered portable SSD. It will run Linux, or rather, Android.
Some planned features:
- Bluetooth master and slave connectivity
- Custom apps will allow use of PSD as part of your normal Bluetooth PAN.
- This allows you to control and copy files from your smartphone and tablet with our app.
- Music can be played through bluetooth headphones.
- USB powered, charging, device and host (USB OTG) modes
- can act as media device or mass storage (or debug)
- can act as a host to sync files from memory cards, cameras, USB hard drives without a PC
- WiFi AP, WiFi Direct and WiFi connectivity
- can host a WiFi network, connect with WiFi direct or become part of an existing network.
- share files with multiple devices
- seamlessly expand a phone or tablet or pc or digital cameras storage
- HDMI output
- can be hooked up to HDMI capable display to show content, stream and play movies, pictures, etc.
- coupled with bluetooth or usb mouse and keyboard and it can be controlled directly.
- poss. model with optional ethernet+
- would poss. use two SSDs for RAID0 for data integrity.
- OpenSource! use it as a pocket webserver, a netflix box, whatever you want.
- device partitioning would allow all devices to have their own storage or share space as you wish.
I am hoping 256gb can be done for under $200, ideally $100.
My question is, would you want one??
I am going to put a plan together to try and crowdfund maybe $5000-$10000 to enable me to assemble a tiny team, get development tools and start building the prototypes and software in order to make it a truly functional and refined product before if or when it goes into production. I have all the expertise I need myself to design it, build it and write the software, but while I may be capable, two heads ARE better than one.. (hence opensource).. I will need some people to build the team to spearhead this....
Comments, feedback, coffee, peanuts, mayhem and doom appreciated.
After reading about the BoxeeBox scandal, I hope I can seriously generate some interest for developing this device, clearly it could have a lot of uses. I would love to make my project as open as possible, and keep it that way too.
I need to generate feedback and interest before I continue, while I want to involve the community as much as possible, someone (ie. me) has to get the ball rolling, I don't want to do that unless the interest is there.
Considering there is potential for the described device to do a lot of different things, and it will be open, feel free to suggest features, functions and use applications.
Even.if you have nothing to say, but are interested, please reply.
Hi! I originally posted this question in the Android Auto section- however its not really related to Android Auto since its more about networking - or internet sharing capability of android.
If I connect a "car-stick" such as https://www.onlineshop-skoda.de/index.php/carstick.html, the car (a Skoda Kodiaq) should be able to provide a wifi-hotspot.
I could simply enable internet sharing using my Samsung S9, but I guess the signal would be better if the cars built in wifi-hotspot capability was used.
The phone is connected via USB to the car.
Could the phone be configured in some way which would enable it to present the type of network interfaces similar to what the earlier mentioned car-stick presents?

Your question is 100% not clear.
A recent broadband dongle is just a cellular phone w/o keyboard and display that shares the connection via USB networking.
Practically the same thing that an android Phone does when you enable the USB tethering.
The only relevant difference is that the former does that by default, while the latter requires a manual input.
BTW you can automate the usb tethering using tasker or some dedicated apps available on the store
