Hi,
Anyone know how to connect bluetooth to
O2 XDA? Thanks.
Bluetooth usb adaptor F8T001
Use bluetooth usb adaptor F8T001.
The XDA can only be hooked up as USB slave. Meaning it can only talk to a computer, not to peripherals, such as bluetooth adapters.
What?
That BlueTooth adapter is for adding Bluetooth to a computer with a USB port. That is the Belkin adapter.
That wont work.
IF someone has seen something... Id like to know... but as far as I know its not possible considering the SD slot does not support SD/IO and a serial implementation would be bulky. Furthermore the USB sync connection does not offer USB host which is what is needed to use USB devices. To my knowledge there is only one or two Pocket PCs that have this. The toshiba and one of the Cassiopeias.
BeDammit
YellowTab... the ressurection of BeOS
long usb sync connection
No bluetooth on Xda.
Only option is to use a very long usb sync connection?
bluetooth with usb port?
Hi,
Anyone know if there is such thing as a bluetooth with usb port?
Thank you.
Yes, but it would not help you since the device can only talk to USB-equipped computers, not to USB devices. To use BDSM terminology, it's a 'slave' and not a 'master', and doesn't like reverse roleplay.
I am lost here
I just dont understand why there is no way to use bluetooth on Xda
since you can use a usb sync cable or infrared to synchronised the
xda & desktop pc. Can there be a blue tooth unit at the end of the
usb sync cable that hook up to xda to received the signal from the bluetooth adaptor that connect to the desktop pc usb port. I thought
it is like just cutting the usb sync cable and using sort of wireless
medium to joint their ends. I understand a little bit about xda being a slave device etc but dont understand the part that you cannot use
sort of connections or adaptors etc to transmit signal? Maybe those
guys from bluetooth,SIG, will look into this area. So far as I know
they only have bluetooth to connect pc to printer and keyboard.
Seems like they say something like the OS of xda will not accept
bluetooth etc.. Hope you experts can enlightened me. Thank you.
Yeah, no problem! Go stick a Blutooth adapter on the end of a USB cable........then come back and let us know when you have paired the two devices up.
Hi everybody,
I´m new in here, so please forgive me when I'm asking stupid questions or anything
several things I found out so far :
first of all, of course there is a difference between a USB host and a USB device, as BeDammit pointed out correctly above. To use USB devices, the XDA would need host function instead of its built-in USB slave used for synchronisation. Generally speaking, there are just a few devices offering both host and slave function, since there are only a few USB chips offering both (for the developers: Philips has just launched some new of these chips).
For PDAs with Compact Flash, there is a new solution, which you can check out here : http://www.ratocsystems.com/english/products/subpages/cfu1u.html
(If they'd only had a SD version... :? )
Nevertheless, a synchronisation via bluetooth should still be possible since xda would only be a slave. There are some guys here in Germany offering Bluetooth Headsets via ebay, article number is 3329163765. On this auction's site they say : "don`t keep telling us your xda has no bluetooth; we know that. Therefore you will be delivered an additional bluetooth adaptor " (sic!)
I have not gone further to this so far, for actually I don't have my xda yet... 8) , but maybe this helped you a little further...
<half an hour later : >
I got it ! I got it ! It's made by Toshiba, but compatible. Check it out here :

Interesting
Anyone care to look more closely into this product and give us some feedback? Unfortunately I don't have the skills to do such a thing.
Cheers!
XDAs do not support SDIO cards, only SD memory cards...
(And doing a search in older messages would have revealed this same answer, only about 50 times...)
I have heaRD THAT o2 MAY BE RELEASING AN xda with triband and 64Mb ROM c/w bluetooth. A dealer told me but no word on the net. The XDA 64i apparently.
Anyone else heard that?
E-Ten P700
Yes, I got a reply from the supplier E-Ten who told
me The new device with bluetooth will be call E-Ten P700.
It is similar to O2xda just like their older version P600 series
but this one will have bluetooth. Their P610 has wifi 802.11b.
But the new P700 will only be release Q3. Most probably O2xda
new release might be around the same time. Cheers
I've looked around here a good bit and can't seem to find info on the USB functions of this device (I have an 8500). I've read where somebody got an external memory card to work through the cable, but what I am kind of curious about is do other USB devices work as well? Ie, if I get a cable with the appropriate ends on it, could I hook up a keyboard or, more importantly (and at the risk of "Read-the-massive-thread" flaming) an external GPS antenna (such as the one that comes with Microsoft Streets and Trips)?.
any ideas?
sorry if this is posted in the wrong place.

In any USB connection, there has to be a "bus master" device, which "directs" all the other devices, and manages the transactions. This operation is usually done by a PC; while there are other pdas (I've seen HPs do it) which can be "reversed" and turned into bus-masters, no HTC device can do this. It is a hardware problem, as the pda needs some special hardware in order to be able to act as a bus-master. As a usb bus can't work without a bus-master, two "client" devices (such as your hermes and a usb memory stick) will not be able to work together.
Sorry!
The Samsung S3C 2442 processor used by the HTC Hermes actually does have native USB Host support per Samsung's documentation here: http://www.samsung.com/products/semiconductor/MobileSoC/ApplicationProcessor/ARM9Series/SC32442/SC32442.htm.
Now if the wires are connected or not, that's a question I have not yet dug deep enough to answer. Maybe, maybe not.
The ETEN M500 supported USB Host while the M600 does not. These devices are identical hardware as far as I could tell, both using the Samsung S3C 2440. The difference is Windows Mobile 2003 on the M500 vs 5.0 on the M600.
This indicates to me that Microsoft has either omitted USB Host support which they previously included in the operating system, or a change in the OS has made USB Host very difficult to implement.
Hope this helps somebody figure out a way to hack USB Host onto our devices.

Thanks for the reply Trane. this would be really handy to have working. Perhaps soemone else will chime in.

Ok, I just ordered a 32GB USB Flash Drive.
Some people report that the Athena recognizes some flash drives so I was thinking...why not remove the MD and take apart the 32GB flash drive and put it inside the Athena. Then solder the USB pins together internally so the USB drive is always connected internally to the device?
I haven't really put serious thought into this but wanted to run it past everyone and those hardware experts to see what every ways.
I have yet to look up the MD power requirements and compare those to the USB power requirements. Either way, if it's recognized it could mean a real upgrade to the device and we could always write a simple program to enable/disable the USB drive if power consumption is too great.
Your thoughts people on this?
EDIT
After further thinking I see four obvious obstacles:
- Stripping down the 32GB USB drive so it fits in the device in place of the MD. I'm hoping this isn't that big of an issue but then again I have no idea what i'm talking about. LOL
- 1 have to make sure the Athena recognizes the 32GB USB drive.
- Power Consumption as mentioned above, which might be overcome by utilizing a utility of some sort.
- Since the Athena requires the USB Host cable/adapter to make things like this work, there might need to be some type of mod internally to make this happen. I talking to someone with more knowledge of USB pin outs might help in this area.
-- EDIT: Olipro mentioned that this is most likely a non-issue. That the USB adapter just makes the USB connection a large one so the internal wiring I'm thinking about shouldn't be a problem. This is great news. One obstacle out of the way. Don't you love progress!

hehe u know im always behind ur crazy ideas. lets get this to work!
possible incompatibilities of it not detecting the microdrive but should be able to be fixed by software
possibly will need to integrate usb host controller chip and wires inside as well
make sure not to screw up the charger either =p
but other than that it sounds good
Hi, for information: Athena Servicemanual says you need 3 things to replace if you disassemble your device (On-Off Key, CommManager Key and some rubbers).
So if you really get the USB-Flash running then you'll get problems putting everything together again.
I think you'll get errors because the G-Sensor doesn't detect any Microdrive. (maybe freeze or reset or some other issues?). Maybe you have to shorten the G-Sensor somehow. This will need people who own the original plan of the device and also know how to get information out of it.
But great idea!
Ok, just found out that the host adapter just changes the plug to a larger USB plug. So the wiring should be a piece of cake. Let's keep this going...before you know it the team won't have only brought you a great ROM but also provide a way to have a 32GB Athena and storage you no longer have to worry about and with no moving parts!!!

Thanks for your feedback. I also think this may work and if not with the drive I've ordered with some other USB. I've seen USB devices as small is a dime so this should work. I'll be happy to purchase a bunch of USB drives to see which work. I probably would like anyone with an Athena and a USB drive to test what they have and post the results.
For the record I ordered a Corsair Survivor 32GB USB Flash Drive model CMFUSBSRVR-32GB.
I think there was a group of people(I couldn't remember who exactly) who already dismantled their athena when it came out to see which micro drives in the market is compatible with the one installed in the athena. I suggest we find the post first before and read through their findings. There might be something there that may help with this project.
If I remember it correctly, there was even a host of pictures and instructions in dismantling the Athena.
I just couldn't remember other details because I was just browsing around and never thought of owning an athena.

Something I found about USB Drives and the Athena
Wikipedia claims microdrives use more power then flash drives:
"consume more power than flash memory (on the order of 190mA, peak 310mA, at 3.3V) "

Good luck to you this would be cool.

Let`s keep this a short term, realistic and affordable goal. ;-p
USB storage is cheap, easily modified, compatible as it`s already recognized by the device both by the software and USB host capabilities of the device board, etc. Also, those drives aren`t yet available and I doubt people will want to spend over $800usd on them for Athena. No?
Well, IMHO there's two alternatives for such a modification:
1 - either use the ATA connection of the micro-drive with the 32 GB pendrive. Adapters exist, wiring should be tricky due to the size requirements (everything has to fit into the space usually used by the micro-drive);
2 - connect permanently the 32 GB USB pen-drive to the USB port. Removal of the micro-drive is in that case optional, maybe in order to make room.
The problem with the second option is that I am pretty sure this will screw-up USB slave connections, and more specifically ActiveSync. Altough, true, one can Sync through Bluetooth.
Two problems with the first alternative:
- G-Sensor, without a md, will no work anymore. BUT it can be disabled in a software manner, so that's no big issue aside from the fact that we won't be able to "tilt'n scroll";
- finding a compatible USB / ATA adapter (those are known to be... "capricious").
I find the first alternative much sexier, personnally... And it DOES get me thinking.
Why not just use one of theose new 16 or 32GB MicroSD/Transflash, or whatever the hell there called cards, just released at CES.. It would save ya
lots of work, and you wouldn't have to crack the Advantage open.
Yep, that's also being discussed on the forum.
But I do agree that having solid-state 32 GB instead of mechanical 8 GB in my Athena would suit me just fine.
Jointly with a 32 GB SDHC card, of course.
:-D lol
I currently have the 8GB SDHC....of course I'm going to buy the 16 and then the 32 as soon as they come out and I can get my hands on it...but my goal here is to replace the MD. After thinking it through even further, we could even setup an internal type of mechanism so as USB drives become larger and cheaper, we could just pop out the old and pop in the new thus continuing to increase the internal storage of our devices.
Maybe I'm just dreaming but replacing the MD seems to be a goal that we can achieve quickly and cost effectively. We've had the discussion of getting larger MD's...but always ran into obstacles we probably couldn't overcome. They are releasing large SSD's but we may have to mod the internal connection, etc. With the USB idea, the connection exists, compatibility is there, and it's very feasible. I'm just excited. LOL

I'm thinking more simplistic. Take out the MD and dock it connect to. This frees up some space. Strip down USB drive as much as possible and hope that it fits some way into the device. If it fits, we can mount it in there in a number of ways. Solder 4 wires from USB drive to USB host interface on the board. Write some software to control (activate/deactivate aka mount/dismount) the USB drive and see how it goes.
2 - connect permanently the 32 GB USB pen-drive to the USB port. Removal of the micro-drive is in that case optional, maybe in order to make room.

Not sure what you mean exactly but...I want the USB drive to be internal. Of course I could get some velcro and stick a 32GB USB drive to the back of my Athena, etc...but that would just be ugly.
You also need the USB host cable to do this unless you want to solder wires and run them from the outside of the device to the inside USB host pins. Let me know if I got the wrong picture here.
The problem with the second option is that I am pretty sure this will screw-up USB slave connections, and more specifically ActiveSync. Altough, true, one can Sync through Bluetooth.

You bring up a very good point. I'm going to have to take my 4-in-1 cable and try to run a small USB drive while trying to ActiveSync. I wonder if that will still work. If it fails, the mod I'm proposing may cause a problem with ActiveSync connections. Anyone else have comments and/or ideas on this?

I'm hoping we can do it without any adapters. Just straight soldering of the 4 USB wires needed to communicate. Should suffice. I found that I don't really use nor need the G-Sensor on the MD. For sure can be disabled in the ROM. The Athena Project team would just have to make a Special Edition ROM for those that do the mod.
I posted a few weeks ago about a SSD that Intel will be releasing soon. I believe it will be a drop-in replacement for the existing drive.

I actually read that thread a little while ago. Do you know when it will be released and how fast they will get up to larger drives like 8, 16, 32, etc. GB's?
ia ctually dont think you will run into active sync problems...
reason being i remember a special cable that came with my friends hermes that split the usb port into two
one for charging and one for syncing...
so i think if we disable the flash drive when syncing it should be fine

I have tried a usb gps dongle that worked on my Odroid T running froyo, but it did nothing just like all peripherals plugged into usb port other than keyboard and storage devices
..........
Ive spoken to two of the devs about support for usb gps, basically a new lib would need to be created for the driver to get these working, and with the aprouch of honycomb, it was suggested that we may get one for hc, but in the end i went out and bought a $15 bluetooth gps that works like a charm. So once HC is released for the gtab, with some luck one of the devs will be able to sort out the lib driver issue. till then bluetooth gps is what we have.
Where did you find one for $15? The cheapest I've found was $35 so I've been using my slightly broken Droid 2.
Was lucky to get it from ebay at that price, they do normally go for a bit more. But thats the nature of ebay as i see it, sometimes you get a bargin, sometimes you dont.
Can you share the make/model type for the one you got? Thanks in advance.
Sure mate, i got a AVLabs Bluetooth GPS Receiver.
I too have been trying to get a USB GPS to work. No luck yet, but I'm getting closer. I do have a BT GPS somewhere, but I just have not found which car, or what desk I left it laying on yet.
I'm running Vegan 5.1 with the 5.1.1 add-on plus I added the kernel from ClemPatchTNTVEGANZPAD. That kernel includes the pl2303 driver so now when I connect the USB GPS I see that /dev/ttyUSB0 is created. I can run stty to set the baud rate and if I cat /dev/ttyUSB0 I do see the NMEA sentences from the GPS.
I'm still lacking the know-how to map this port to the system gps provider though. I'm pretty new at Android in general. I tried adding:
ro.android.gps.provider ttyUSB0 (or something like that)
to build.prop, but so far - no luck.
I've also tried running GPS2BT on my phone along with BTGPS on the G-Tab, but I have not got that to work yet either. I'm convinced that I just need more fiddling around time to get it to work.

Wondering if anyone here has been able to use a 3g dongle using otg cable and y-cable? Does ICS have any drivers built in?
Thanks
Bump anyone?
What is an otg cable and y cable?
Otg. Cable is basically micro USB to USB cable and y cable is required in order to provide power to the device you'really using.
I'm pretty good at figuring out bad lingo but I'm not quite sure what you're trying to accomplish. Are you trying to get 3g on your touch pad or power the 3g dongle like a hotspot? I'm assuming the micro USB to USB plugs into the touchpad and part of the USB "Y" cable and the dongle into another part of the "Y" but what does the y cable plug into? Being detailed and descriptive goes a long way to getting answers on the interwebs.
Sent from my SGH-T989 using Tapatalk
Figured the people that would know if it works/how to get it to work would already know what the cables are seeing as its the same equipment required to hookup any USB device, be it a keyboard, USB flash drive or external hdd to the touchpad.
Basically I want to use the 3g dongle to get internet on the TP. To do this would require external power to the dongle as the TP doesn't have a powered USB host. Most likely require drivers as well.

At least in the US, tablet device plans tend to be cheaper than tethering plans and carriers are starting to crack down on such practices. Its a valid request.
Not really sure if its possible on the touchpad, but I know some other devices are capable of it like the Archos G9 series and some Chinese tablets so I would not be surprised if it were.

I think most US carriers would be unhappy if you used a 3G USB Modem with a tablet plan since the modem could be used with a laptop too. Pretty sure it would be against ToS to do so.
In any case, if that's the route someone wants to go, then wouldn't some sort of 3G Wifi hotspot still be better than a "franken-dongle"?

Good point on both accounts. A mifi type device would probably be the way to go, less cables, more universal usage, etc. Only downsides being that its pricier than a 3G dongle and the battery life would not be as good, but it would be guaranteed to work.

Yeah, i tether via wifi to my android phone all the time, i also use it as an external gps receiver for my touchpad. It just seems much easier, i'm already paying for the data plan why the hell should i pay some ripoff carrier another 30 bucks a month for data on my tablet. This would however be nice to see if an external dongle will work.
all valid points. I currently tether to my phone as required, however work has issued me with a 3g/4g(LTE) usb dongle that i would like to be able to use (in addition to all the other 3g dongles i have lying around).
I've seen the wifi adapters on ebay that you can just plug the usb dongles into, but to avoid shelling out extra $$ i thought i'd see if there was any in-built or easily implemented support for usb dongles.
Having seen the cheap chinese/ebay tablets running GB with usb dongle support i figured surely there must be drivers out there that could be adapted to work with ICS.

Looks like someone did it with a wired dongle for the Touchpad...
http://forum.xda-developers.com/showthread.php?t=1552102
So maybe someone could do the same for a 3G dongle?
And it also looks like there's a way to a 3G dongle working with an Asus Transformer on Honeycomb...
http://forum.xda-developers.com/showthread.php?t=1151097
although it takes quite a few steps and doesn't work on ICS yet.
I also found this...
http://it-depot.net/pages/3G_Setup
But the guide doesn't mention what tablet or version of ICS this should work on. On my Touchpad running CM9 nightlies I don't have a Mobile Networks options. Between the vagueness of the guide and CM9 being an alpha, it's kinda hard to figure out what the issue might be.
I guess your original question was, has someone made this possible for a Touchpad already? And it seems to me that the answer is no, but it eventually might be done. It looks like you're not alone in wanting to get a 3G USB modem to work on an android tablet, if that gives any hope.
Thanks gmkelly.
I'd seen those links before and tried to find that mobile networks option. From what i can tell, it looks like ICS might actually have some drivers built it, but whether they are in CM9 is a different question.
I also kept a close eye on the wired lan adapter thread posted yesterday (?). If a wired adapter can be implemented, maybe it wouldnt be too much effort on getting the wireless 3g implemented...
Forget US carrier restrictions. This feature would be an absolute godsend in a country like Nigeria where a 3G dongle is pretty much the best way to get online in most places.
The only issue I see with this is that a lot of 3G dongles are only Windows / Mac compliant. Meaning that they hate linux or anything that isn't Winbl0wz XP (or 7) or Mac OS X 10.5+. And Android definitely doesn't fall under that category. Just like consoles (which I have seen people try and use the dongles for, too).
However, if you CAN get them to work, you'll be a hero in the tablet community.
3g dongle works with hp touchpad now. Check Josh's PPPWidget forum. I am using a ZTE MF110 with it on CM9 and get better performance than on a win7 machine.
