Has anyone use a usb rs232 yet? - Nexus 7 (2013) Q&A

Does not work?

They typically require drivers and emulates a serial which I don't think android handles.
I thought of this myself as I need serial to program network gear. Would be awesome to get a serial terminal emulator working.
I even though of a Bluetooth/serial dongle, but I don't know how that would work with terminals either.
Doing a quick search on Google, there seem to be lots of Bluetooth terminals that support a Bluetooth serial port. That would totally be awesome but most likely require some sort of battery for power since I'm not sure if a serial port would provide enough to power the Bluetooth.
Serial Bluetooth Devices seem expensive too.

Can someone guess at this adapters function

Hi all,
The atom has just passed FCC testing and in the documents was the attached picture. Can anyone tell me what they think this adapter is??
I am trying to find a method of bringing the VGA screen out onto a monitor without the need for a PC or activesync, to provide universals instead of laptops for my staff. This may be the answer or can anyone suggest whether it would be theoretically possible to use a wifi enabled monitor and software such as nydots new pocketpc software.
If you have any other ideas for possible methods of turning the universal into a desktop/laptop replacement please let me know.
thanks
jayman
Looks like it could be a dsub monitor lead, but then again, resolution is low so it could be a serial lead?
However, consider the x50v for tv out.
Alternatively, see if this works for pda > monitor

The dsub's are definitely only 9 pins, so it's not a VGA connector. I have no idea what it is... it looks like two mini usb connections, one standard usb connection, and two serial connections.

That's the opposite of what he wants. It lets you extend your PC's desktop onto your PPC.
That said, though, I just downloaded the trial version and I'm trying it now. It's seriously cool. I have absolutely no idea what I might use this for, but it's still really cool.

BrettS - I understand that sidewindow works PC to PDA (and it is great, although a bit gimicky ), but I wrote PDA to PC so that he could investigate if they supply anything like that.
I can't think of any solutions that capture the PDA's screen at fullspeed really...they're all quite choppy so not ideal.

looks like a x2 9pin serial adaptor to x2 mini usb connectors. and a power input to deliver 5v to the JJ for mains power.
i think it could be alot simpler cable than percieved
You could try this, but I'm not sure if it works with WM5 or not...

Thanks for your input, I have had a reply from O2 stating that this will not be compatable with the Universal.
However they did state that they are working on their own solution that should be available within the next few months. Which will also allow time for ROM upgrades to repair early video bugs and speed issues.
I will keep you updated as I learn more.
The idea is that as the majority of my staffs work will be calls, short emails, reviewing small compressed videos and data input into a web based database, that the universal can provide all these functions. A 15" screen that provides a minimum of 640x480 resolution will be easier on the eyes and a bluetooth keyboard can be provided for touch typists. This will save on desktops laptops and mobile phones.
I hope O2 provide a solution that provides a multiplug such as on the XDA2 expantion pack. This will then allow you to use hotel TVs as monitors.
It allows you to play video and presentations stored on your XdaII through a PC monitor/Projector via VGA jack or TV via video or s-video jack.
Resolution supports:
For LCD display: VGA 800x600 and 640x480
For TV output: 640x480 NTSC and PAL system

anything which is usb connected would require the device to be able to act as usb host to be able to transfer slow! tv or monitor out using usb
non of the HTC devices do usb host
some say that universal does but nobody have been able to confirm it
if it did one could use one of the usb video cards you can get
that is if there were drivers for pda's for those
I think that replacing laptops would be a VERY bad idea; JJ is a far cry from laptop power, the office apps are seriously crippled compared to the real thing, and emailing is not html. And all at twice the price of a small laptop...don't think so.

Radio Broadcast unit for Orbit?

Hi,
I was wondering if there is such a device that allows you to tune into a radio frequency and receive your mp3 / wma music broadcast over. It would be handy for the car. I know its really creating a pirate radio station but the Apple Ipod's have the technology.
Thanks
Michael.
You can do this, you will need the mini-USB to 3,5MM addaptor cable (search the forum, it is listed in many places within the Artemis section) then get an FM Transmitter, they were made legal for use in the UK at the begining of last December. In use they are not perfect with signal loss/ other stations bleeding into what you are listening to - PC World for a legal device or E-bay and take a chance - Mike
Can anyone find a reason why this wouldn't work as it seems like the perfect thing to do this. FM transmitter that connects via mini usb.
I don't know where you can check this, but many countries changed their laws affecting "illegal Radio Stations". In Germany for example the FM Transmitters are legal by now, as long as they don't radio over more than say 10 metres.

I don't suppose there is any way of knowing this without actually buying one is there? I don't fancy spending £30 if it won't work .

I've heard this before, but I use the same USB cable and charger for my Orbit as for my RAZR V3 and they both seem to work correctly (i.e. they charge and sync to Wintel AND mac).
What exactly is the difference? Isn't USB a standard, there should be no variation.

My caution was about the fm radio. If this was true for the fm radio, we could all listen via speakr phone using "any sync/charge cable at all"
Isn't that more to do with the way the orbit/Artemis implement its FM aerial rather than any differences in the USB pinouts?

cable or bluetooth to GPS?

Does anyone know if I could get a USB GPS receiver (such as the GlobalSat BU-353) to work with my elf if I connect using a female-mini usb converter?
I'm thinking that this would draw less power than using a bluetooth GPS receiver - would this actually be the case?
Cheers
K
i would say yes bluetooth draw more power but gps's are normaly used in cars where one can charge ones pda at the same time
Yes, but with a bluetooth receiver I'd end up using two chargers rather than one and I'd also like to use away from a vehicle. Would the usb connection charge as well as 'talk'. I'm not entirely sure how standard USB maps to mini USB to be honest ...
i dont believe that a wired gps device can charge the pda
also with htc devices (with 1 exception) cant use other usb devices
as they cant usb host
Thanks, it sounds like I'd be better going for a bluetooth GPS
Spend a few pennys more and get the entire gps unit. Are you realy going to be able to operate your phone as a gps interface while driving? Sounds like a great way to get a ticket ot me state side.

Possible to make "shell" to turn it into a netbook?

(Apologies if this has been asked before or if it's mind-bogglingly retarded.)
What we have with the SGS2 is remarkable - it's as powerful as a netbook, with video-out and USB host functionality.
It seems to me that carrying such a super-phone alongside a netbook would be a waste of money and effort, when the processor in the SGS2 is more than up to scratch.
So what would be the obstacles in making a "shell" that provided a laptop-like keyboard, mouse and screen, with an SGS2 where the processor, RAM and so on would normally be housed? (The SGS2 would be removable, of course.)
These are the ones I can think of:
USB/Bluetooth keyboard support - may have to be Bluetooth keyboard.
Touch input? (May have to be Bluetooth mouse, but mouse input is possible in Android)
Connecting a monitor and USB device through the same USB port (not necessary if keyboard/mouse are Bluetooth)
Battery life - just make the shell house a fat battery!
So let's say we could piece all that together - a keyboard, mouse, battery and screen in one shell. It could come out considerably cheaper and lighter than a netbook, with all the SGS2's media playback abilities, internet without having to tether, and no need to change apps when going from netbook to phone.
There's probably something I haven't thought of, but I couldn't resist posting.
Thoughts?
I would love to see something like this happen. The SGS2 will be my first Android phone, coming from WinMo, so I've no idea what is available or is possible with the OS. One reason I bought this phone was because I wanted to connect a Bluetooth keyboard (and mouse?) to it and keep it mounted on a dock or stand right below my two monitors at work, serving as an internet/chat/email computer, instead of taking my phone AND laptop to work every day.
Now I may be mistaken, but MHL doesn't support simultaneous USB and HDMI out, so if you wanted to connect input devices AND have monitor out, I'd guess the keyboard and mouse would have to be Bluetooth, as you've mentioned. One thing that interests me is something the Wiki entry mentions:
"The HDTV remote will control the connected device with guaranteed mixed manufacturer interoperability."
So perhaps one day we might see some SGS2 "lapdock" like the Atrix?
Check out what the guy says at 8:50 in this video: http://www.youtube.com/watch?v=ZtwTcnR0hqA
He says, basically, that he can connect the device to a tv through MHL, connect a BT keyboard and mouse, then sit back on his couch and use his device like a living room PC.
Bump...
Any news?
I put it in the top lid of my logitech dinovo mini with some rubber bands.
Looks like sh*t, but works really well!

You won't be able to do a full netbook, because the microUSB connector on the SGS2 can be used either as microUSB or MHL (HDMI video out + charger input); the two functions of the connector are mutually exclusive. So, if you're piping the SGS2's video out to the shell's display, you have no USB, and if you're using the USB, there's no external video.
You might be able to use some kind of remoting software to work around this & use the USB functionality of the SGS2; the shell would have something like a VNC client installed, then connect to server software on the SGS2 (over WiFi or BT networking).
Hm, are you 100% sure about them being mutually exclusive?

Interesting, but I would still prefer a full size keyboard.
How is it connected? USB? BT?

No idea how this can be realized. Afaik, there is a VNC client installed, but no server.
Guess it is easier to try what is mentioned above :
Use NHL to get the monitor working and BT for the keyboard. Would be good to have some profile, which enables the BT keyboard when NHL is plugged, maybe through locale or so.

I know this thread is kinda old now, but some recent tech news brought this idea back to memory for me. ICE Computer showed a docking tablet they call Trinity at Computex 2011, which apparently can be made to dock with nearly any phone or even a PC module. I didn't find too much info that wasn't regurgitated between sites, but it sounds like they won't be selling it themselves, rather they'll sell it to other companies who want one for their device.
My hope is they'll sell some kind of universal version that takes different phones and maybe just requires a different-shaped module for different phones. Here's a link to the Engadget post, but there are other pages that describe what it does and when it should be available.
http://www.engadget.com/2011/06/01/ice-computer-shows-off-trinity-modular-tablet-concept-aims-for/
Add a Bluetooth keyboard and mouse, perhaps a stand, and voila!
Need a solution like this
1) MHL output to a tv/ monitor
2) Bluetooth keyboard and mouse work over HID profile
3) Remote Desktop software that allows use of external keyboard and mouse and which can output native resolution rather than just mirroring the screen.

Serial output from watch active 2

I'm looking to use the watch active 2 as a flight computer for a model rocket and I was wondering if there is a was to get some kind of serial output from the watch unit. My plan is to use this to control additional hardware such as camera, parachute deployments etc. I would like to avoid using a blue-tooth connection as I feel it may be too unreliable for some feature. is there a diagnostic pad or chi charger command pass through that might be able to work for this?
