[Q] Can you make your phone act as a RF transmitter? - Nexus One Q&A, Help & Troubleshooting

Hi,
I saw a video recently about how an unrooted N1 can be used as a remote (for Logitech Rouve). I am curious to know how exactly that works, and whether we can develop our own remotes like that?
My guess is, its somehow using RF ... am I wrong in assuming this? I want to know whether there is a way (or, if someone can direct me in the right direction) to make a nexus one act as a RF transmitter by attaching some piece of small hardware (either DIY or bought from somewhere else).
Any help is much appreciated!
Thanks!!

Remote controls of home equipment work by IR.
Nexus doesn't have IR. It can remotely control stuff by connecting through WiFi or BT, and assuming there's SW running on both sides that will make the control possible.
You can't transmit RF in any way, unless it's WiFi or BT. And you can't connect anything to Nexus, unless it's a USB host, or unless you run USB host drivers on Nexus and have a specific supported USB device that you connect.

N1 -> wifi > Rouve > tv

802.11 via XDA connector ?

They have GPS receivers that work through the bottom cradle connection for IPAQs they also have other devieces like keyboards that work like this.
Would it be possible to develop a 80211 dongle that could click into the
cradle port? is anyone working on this? is there anyone that would have
enough knowledge to beging working on this i could contact. I would love to get 802.11 for this baby.

No, sorry. The XDA connector on the bottom supports USB and serial. However, the USB will only do 'Slave Mode', i.e. act as a USB device towards a computer. There are USB 802.11 devices, but they work as devices as well, and thus need a 'Master' to talk to. And there's no serial 802.11b transceivers out that we know of.
You could conceiveably build a USB device that plays the master role and feeds the IP through just like ActiveSync does, but nobody has done that yet. For the manufacturers this shouldn't be that hard, given the amount of spare processing power on these 802.11 tranceivers. (And while we're at it, we might as well incorporate a GPS connected to the serial port...)
hmm
so this won't be something that a little hacking group such as XDA developers would be capable of?
Hi
In a short time a wireless lan card will be available which you can plug into you SD Slot. See http://www.sychip.com/wlan-module.html
See ya

Helllo.
I don´t think, that the wireless lan card will work in the XDA. In the technical PDF there is a picture that shows a SDIO-Interface.
XDA still do NOT have a SDIO-Interface.

hold on, why do u need a wireless lan card? I thought the xda was a wireless device, surely it ought to have wireless connectivity built into it? If you had a corporate wireless network, cant it just be configured to connect?
Of course it has wireless support, using GSM and/or GPRS and infrared. But WLAN support is something entirely different, and that is definitely not included.
Shouldn't be too hard to design a WLAN adapter acting as an USB master though. With the pass-through functionality built into the activesync software it has definitely been shown that the USB connection can be used for network access.

Yo bamse,
Ever want to be very, very popular ? You would make hero of the month on our charts, that's for sure...
What about these guys:
http://www.datahunter.com
I know it's RS232 and not USB, but apart from that the Liberator should do the trick almost straight away, and they also advertise a module that could be built into a sleaker package:
OEM 802.11 WLAN Mini-Modules
OEM and ODM manufacturers can incorporate FCC ?Modular? pre-certified 802.11b mini-modules into their products. The Data Hunter 802.11 mini-modules have the Operating System Wireless LAN software drivers built-in. Interface options are the ones Engineers need, including high-speed async logic-level or RS232, SPI processor interface, USB and full Ethernet TCP/IP. No additional FCC certification required for the modular 802.11 data radios. Start shipping integrated WLAN immediately. Includes single antenna for bulkhead mount or dual diversity antennas

I could be wrong, but from their site I get the strong impression none of it is done, and they'll start work on it the minute someone orders a few thousand.
Also: they base everything on the Compact Flash 802.11 cards with some extra hardware, which is unlikely to pretend it's a PC running ActiveSync straight out of the box, so some extra work is in order.
What we need is a CF 802.11 card that comes with an SDK for adding your own code. No need for extra parts and power consumption: the card should have enough spare cycles to pretend it's ActiveSync on Windows plus the USB. (Or serial at 115.200 if that's somehow easier). Then all we need after the two manmonths of coding is a nice plastic stick-one case and we're done...
Ok, how about this then:
http://www.tuanistechnology.com/products/avaya/converter/
Or this:
http://www.autodnc.de/ctwlani.htm
You'll find a whole bunch of them out there, all serial and 115200bps, but none of the companies seem to have identified the PDA-owners a market for their produkts.
I'd say most of these products use way to much power for PDA use.
Really, let's not build stuff that's already on the PC or CF card to begin with.
Anyone found a way to access 802.11b yet? I see that Linksys has the WCF12 (The Wireless CompactFlash Card installs directly into your Pocket PC using a CompactFlash Type I or Type II slot). I think that fits the IPaq. I need one for the SX56.
I saw some creative ideas above. Anybody try matching the pin-outs yet??
:roll: Sigh. Read my lips. It won't work. It's not a matter of "pin-outs." It's far, far deeper than that on both hardware and software.
And really, would you want to access an ethernet network at 115k??? What for?

While I doubt that anyone will, it ought to be a small task to design a Bluetooth interface that will work with SDIO or SD either as a polled device or memory mapped I/O. For Bluetooth this should produce acceptable results --- for 802.11b clearly it would not.

It certainly seems doable. What is the limitation on the SX56 that does not exist on iPaq? And since I struggled through years and years of 36K dialup before DSL, for the limited data access needed for a PDA, 115K seems like heaven. Noone is going to treat it like a workstation. But access to remote data has a wide range of applications.
The iPaq has an expansion port, the XDA does not.
Carlos:
If you have a quick look at one of the links I have provided above you should find that there are a couple of solutions available for anyone who would like to connect a 802.11 device to a serial port. They may be a little bulky and power hungry, but that can surely be taken care of.
There will be 256MB SDIO card with built-in 801.11, right? What about a 256MB SDRW card with built-in SDIO and USB-host? With the USB/serial/power/peripheral connector of the Qtek sitting next to the SD-slot you could easily build a device that connects to both "ports". Wouldn't it be nice?
wi-fi stuffs for Qtek
Hi Bamse,
Could you tell me what exactly that I would need to purchased
to have my Qtek works with wi-fi? Thank you.
None of it exists today. Everything posted so far is theoretical. It will never exist. There's no market for it.

Turn wizard into Fluke network tester?

Is it possible to adapt the wizard to be able to function like a http://www.flukenetworks.com/fnet/en-us/products/NetTool/Overview.htm
Firstly is there a way to be an ethernet connectible device (maybe via a usb/ethernet dongle??)
Then is there any software capable of checking the reading from the cable to test for connectivety to the wired network and then also to analyze data (Ip addresses/ gateway addresses etc).
I realise I'm asking a lot of this device but if anyone has attempted it I'd be interested to know.
Cheers
?
I'm pretty sure the Wizard can't host usb devices due to hardware limitations, but don't quote me on it. Same with SDIO. It can host a BT gps, so I think that and IR would be your only options. I'd sure love to have a DMM and/or 'scope in my pocket all the time. That would open the door for oxygen sensors and data logging galore. hmmm....very interesting
ok, they make em...googled bluetooth multimeter....but I could buy a real Oscope for what they want for em

Best way to control a robot for the least $$$?

I have a robot lawnmower, Friendly Robotics Robomow RL500. It's like a Roomba for the lawn, you set it loose and let it go. Problem is, it's not very smart. For one, it gets stuck on occasion, requiring me to check on it regularly and free it if it gets stuck. It also needs to be driven out onto the lawn and turned on, and when it's done I need to go find it and drive it back. Worst of all, there is a part of the lawn that is too narrow for it to function automatically so I have to manually mow that part with an annoying wired controller, and it is much slower than a regular mower so walking behind it at a snail's pace holding a wired controller is very boring.
My idea is to make it so I can put a camera on it so I can drive it via Wifi from the comfort of my home. Somehow I will need to be able to stream video over Wifi and send commands to the robot as well, and whatever device receiving the commands will need to be able to activate the switches on the wired controller.
2 ways I thought of to do this:
1. Use one of my extra Windows Mobile phones as a "brain". They all already have a camera and Wifi. All I would need is the software to stream video over Wifi and a control program to control the robot. Microsoft has a Robotics Studio that may help me to write my own program using VS.NET. None of my phones have a serial port or USB Host controller, so I was thinking maybe I can use a Bluetooth-to-UART board and connect that to some kind of controller to activate the switches on the control panel.
2. Use a WRT54G and run Linux. This will probably cost more because I don't have a 54G. I will also need to buy some kind of camera for it, like a networked camera. It has an RS232 port that can be used to connect to some kind of controller to activate switches on the control panel. I KNOW this solution has been done, because there is a video out there of a 54G-controlled R/C car being controlled via Wifi and streaming video back. I would probably need to write my own program in C in Linux (I don't know C), unless I can find the link to that RC car again and see if that guy will share his source.
Any thoughts on which way is the best way to go?

Modding with bluetooth hardware

Does anyone know a way to use the hardware from an old phone to add bluetooth to a PS3 Guitar Hero controller? I found out that the GH controllers do not have BT natively, and instead rely on a RF connection to a RF matched dongle attached to the PS3. I have the controller, but no dongle, so I thought it might just be easier to cannibalize an old BT enabled phone (perhaps a Moto W490 or RAZR) to connect it. I know that this could come with having to make a boarde and program it, which I am ready to do if necessary.
Thoughts? Has anyone done this successfully before? Is this even possible???

Android Auto Wireless Adapter for Standard Head Units

I mean, this can't be that hard right? We know USB data can be transferred over WIFI. Thats probably what is behind the tech of the new wireless feature in the head units. The car has wifi, the head unit knows it and uses it with your phones WIFI and blue tooth in tandem.
I can't really rely on GM to update their Android Auto head unit even though my car has WIFI and it would be easy. They just wont do it. So, I was laying in bed brainstorming. There has to be some small dongle out there that plugs into the cars USB port and uses your phones wifi to connect to it and create a USB connection as if it was plugged in directly. Then the head unit wouldn't need the wireless feature.
Or, you plug the dongle in, and the the Android Auto head unit knows what it is, (just like if you plug an android phone in with Android Auto) and the dongle creates a wifi connection with your phone. Then the head unit wouldn't need the wireless feature baked in. This can't be that hard to come up with can it?
I think it may be possible using a few items
1.)Modified OpenAuto (already supports wifi) that redirects or clones AA data to usb
2.) Raspberry pi zero w
3.) this Zero usb adapter
I'd be willing to work on it, but seems like a big task to undertake to modify OpenAuto.

Not that this in any way diminishes the amount of work involved, but I would 100% be willing to donate towards this venture. If you wanted to start a crowfunding or donation platform towards this I would get behind it in a heartbeat!

Also would want to donate. There is a market for this if stable and effective. Let us know.
This seems like it is possible if we get a device that works somewhat similar to how Nintendo used to allow wireless connections for their older consoles. They would connect a USB to a PC and bridge the wireless connection to the USB and LAN on the machine. We would need a USB dongle that can take the wireless commands and send them as if the phone was a native host connected via USB.
It'd be interesting to see if it could be done with a Pi Zero W, as the two technologies are *technically* compatible, indeed, when you connect to the Desktop Head Unit, it transmits TCP data over USB.
Unfortunately I don't have a Pi0W to give this a shot with
I'd be all about this.

That’s great.
Hi Guys,
what about this? Nothing? I've already checked the other solution, but I would like it much better if could be done it with RPi, "natively" redirect the data between wifi and usb. So the phone can connect normally directly by Android Auto app using wifi without any other 3rd app.
Could be possible? Of course I also would donate this project!!!
Best regards,

Yeah, apparently a Chinese company made this kind of usb dongle but only for carplay. They converted the factory head unit with carplay from wired to wireless.
I did asked if this will work for AA, but reply is no.
Any updates??
