Absolutely agree, you know exactly what your talking about.

Higher the frequency, shorter the antenna.

If anyone has ever worked with radio transmitters, it is absolutely possible to transmit without an antenna. Of course you will burn out the transmitter very fast, but it is possible. This is because of the SWR and not being close to the 1:1 match.

So even if no antenna exists it is still possible transmit/receive can still function at a very short distance, and probably without damage because of such low wattage (Mw) in this case.

So in fact and not theory it can work.

Anyway with all that being said, If no antenna exists, hopefully even though its a BGA chip, the pad is soldered to a trace that can be soldered to. Of course this would be out of the scope of the normal user.

But again, this is all a waste of time until the salting results are in..
[Nook Color Android Development] cutterjohn:
hmmm... I thought that I had mentioned this above... oh well... electromagnetic theory is annoying... especially when you're not particularly interested in it...
[Nook Color Android Development] gedster314:
Will you forget about the antenna. The Bluetooth wavelength is roughly 12.5 cm and 1/8 mulitiple is roughly 1.5 cm. Now how about antennas on a chip?

edit: Forgot to mention. You can have bluetooth and wifi on the same antenna. Their frequencies over lap. All you have to do is work it like TDMA (Time Division Multiplexing Access). Phone companies have been doing that for decades. Can you imagine what a trunk line would look like if every phone had a dedicated line. I believe Fiber works that way to.

And if you want to play with one

http://www.sparkfun.com/products/144

I think it's safe to say that an antenna does not need to look like an antenna. So lets stop this bickering over antenna and let the knowledgeable people investigate it. Arguing over stuff you know nothing about, or not up to date with, only discourages the real work.
[Nook Color Android Development] xboxexpert:
Know how the FM Antenna is made by plugging into the audio jack. I wonder if BT Antenna would work the same.
[Nook Color Android Development] spikey911:
I did not think anyone was arguing, I thought we were discussing.

Not sure how this has discouraged the real work, but I apologize for my ignorance.
[Nook Color Android Development] deitiphobia:
That's different. The FM receiver is simply a receiver. You don't have to worry about SWR with a receiver. So you could use headphones or a metal coat hanger for reception. Transmitting is a different beast that requires more attention and precision.
[Nook Color Android Development] giantsfan:
I don't know who is right about this, but it is really not necessary to belittle someone for their point of view. :(
[Nook Color Android Development] Homer_S_xda:
First reports from the Salting team should settle the antenna question.

[Nook Color Android Development] wvcachi:
Those of you who don't follow the Evo forums probably don't know this, but spiicytuna is a very, very good guy to have around on the Nook threads. :D
[Nook Color Android Development] occip:
Yes It sounds very promising, you can notice the triquint chip which is responsible for antenna sharing. This chip must be controlled by wl1272 chip and musn't have any direct connections to omap3621. So my problems are related to sofware stuff.

The next step is to backport the 2.6.32 kernel omap serial driver to 2.6.29 nook kernel, it will allow the use of several bts files from few boards (like zoom2 ...)

About the teardown, few things must be investigated :

FM antenna

wl1271 PCM output --> omap ? (for BT audio)

I think the teardown will help a lot ...

Will bluetooth eventually lead to internet sharing with a phone without having to switch between the adhoc and infrastructure modes?
[Nook Color Android Development] gtriever:
Some phones will already tether to the NC without bluetooth, and without having to resort to manual adhoc/infrastructure switching. For some reason, Droid X comes to mind... ;)
[Nook Color Android Development] techboydino:
As does my Vibrant, a HD2, and a Nexus One.
[Nook Color Android Development] webvan:
The big bonus of Bluetooth would be to allow a connection to a Bluetooth GPS for real time navigation.
[Nook Color Android Development] madfatter:
Droid Incredible tethers to it as well, without having to modify anyhing, even on stock firmware
[Nook Color Android Development] IM0001:
A lot of android phones can host a wifi infastructure signal. The older winmobile 6.x and probably android devices with the older hardware were more or less limited to hosting a AdHoc signal.
[Nook Color Android Development] mystery-vortex:
Bluetooth should use a *lot* less power on both the phone and the Nook should it be available. Bluetooth was specifically designed for low power consumption.
[Nook Color Android Development] DatterBoy:
That wasn't my experience. Tried for a long time to get it to work and it did not until I switched with the adhoc fix. Could have been me though but I had 4 Nook Color's to test with and none of them could see the adhoc network from my DINC.
[Nook Color Android Development] phirephotog:
I'm stuck in the land of iphone 4. I suck at life so bad I can't get the ADB to work to run the script to switch between modes. Was hoping there was light at the end of the tunnel in the form of bluetooth for r-tards such as myself.
[Nook Color Android Development] chaloney:
I've wi fi tethered to a droid x while using it for navigation. no problems, but I didn't use it that way for long. worked though

He's right. It's like 2 bus boys arguing over a surgical procedure. They are out of their league and clearly don't know what they are talking about.

Some news

Hi,

I find a different uart driver in 2.6.29 from motorola Milestone , I have difficulties to get it working in NC. So I'm working hard to port 2.6.32 kernel. I hope it will enable BT at high speed (3Mbauds)

Occip
[Nook Color Android Development] camwinnn:
Woot! :P How confident am i in you guys...

Already set up google callback with sipdroid ;P tho i guess using BT an wifi is still up for grabs? as in possible or not?

Would love to be trying stuff myself but i cant even manage getting to the store to get a BT headset....
[Nook Color Android Development] cal3thousand:
I've never had to do any of this switching to adhoc with my MyTouch4G either.

I'm using Wireless Tether 2.0.5 RC2

*just remembered to check for a new release, going now*
[Nook Color Android Development] f4phantomii:
Ditto my G2....did 5 hours of tethering on the road via wifi and it worked great....no adhoc required.
[Nook Color Android Development] cybertimber2007:
If I remember correctly, some devices when using wireless tether will support infrastructure mode, which will work just like a access point or wireless router. Other's have to resort to Ad-Hoc, which technically is correct based on standards (direct wifi communication), but harder for the user.

That might explain what you are seeing.
[Nook Color Android Development] gtriever:
Correct. My original post was for the cats that might not know that already, and that might want/need tethering

now

. Man, when bluetooth is figured out, that's going to be really sweet.
[Nook Color Android Development] cal3thousand:
I just read somewhere after my last post that HTC is quite good with infrastructure support
[Nook Color Android Development] RoboRay:
Make sure that you're using tethering software that specifically supports infrastructure mode. Earlier versions of Wifi Tether didn't, but the newer ones do and my DINC works fine in infrastructure mode.
[Nook Color Android Development] Divine_Madcat:
Same here - no problem tethering my NC with my Inc; wireless tether Pre15...
[Nook Color Android Development] art.in.memphis:

[Nook Color Android Development] Ophbalance:
I wish I had a phone with wifi thether, but I'm stuck with an HTC Touch that only has BT. I'm eagerly awaiting the day I can tether the nook to the Touch ;).
[Nook Color Android Development] rsptexas:
I applied the ad hoc patch on NookDev.com, and added a Symbian hotspot app (Joikuspot) to my Nokia E71 -- the Nook recognizes my Nokia as an ad hoc connection in the wireless wifi list (ad hoc connections are preceded by a *) ... no manual switching or scripts are required to switch between ad hoc and infrastructure hotspots.

I'm working on kernel porting, I will have some news tomorrow.

My first step is to enable bluetooth in command line and test few bluetooth firmware , as the kernel will not handle wifi,video, touchscreen , audio ,3d and dsp at the beginning.

If bluetooth is ok i will continue to port recent kernel for the NC by adding features by priority order:

video

touchscreen

wifi

audio

3d

dsp

stay tuned

[Nook Color Android Development] pavlos46:

[Nook Color Android Development] webvan:
Not sure what it entails but would serial emulation for GPS be hard to get working?

Can you try bluegps4droid http://sourceforge.net/p/bluegps4droid/home/ at some point? Thanks!
[Nook Color Android Development] bdjohns1:
Awesome work. Getting HID support (ie, BT keyboard) would be great - then I can put my portable BT board to use.
[Nook Color Android Development] aludal:
Could you please elaborate on:

1. "Recent kernel"? Is it 2.6.29, or 2.6.32? or (maybe, just maybe) 2.6.35?

2. By "video" you mean hardware accelerated video decoding AND hardware assisted overlay (rendering)?

3. A "smarter" touch calibration routine is very welcome, yes.

4. I would love to see a "x2" boost in speaker's audio volume/prefs. But it's just me, sigh...

Hopefully an NC CM7 nightly that about to appear any day now will help you.

TIA

Basically occip is having to rebuild a nook compatable kernel from scratch. All of the features you take advantage of now have to be re-done.

If I get a vote, any chance you can roll IPtables in while you are featuring up a kernel? It is need to get proxy working.

Thanks for the update, when you get a chance can you try BlueGPS http://sourceforge.net/p/bluegps4droid/home/ ?
[Nook Color Android Development] KryptoNyte39:
I was thinking more along the terms of ... where is your "donate" button? I know that the donations would probably never be enough to compensate for the hard work, but I wouldn't mind sending a few bucks your direction for your hard work on something that I don't have the skill to carry out on my own (and I would bet I'm not the only one).

The "time" thing isn't really an issue ... it is neat to see some progress whenever there is time.

I do, however, believe that the Nook Color with Bluetooth explodes with new potential, maybe more than any other development on this device.

Thanks for what you do, Occip. I'll keep my eye on this thread.

And once again, if you feel confident in the BT development, a donate button may not be a bad idea.
[Nook Color Android Development] fickej:
TIME = not doing other peoples bidding

Please stop asking him to try this software and that software. Just leave him to what he does best and if you want to help him then you try it and you see what you can do to make it more stable or just pay him lots of money so he can quit his job. Then he would have loads of time to work on it and then you can try the stupid apps for yourself. If you want something tested like apps or gps or a keyboard just wait. They say patience is a virtue for a reason. The more you bother him with this crap the longer it will take. CALM DOWN in the words of the Dude "Will you just take it easy?" --Shomer shabbos!--
[Nook Color Android Development] pmgnet:
Occip, can you start with an existing froyo build for nook?

maybe some of the painful stuff has been worked out already?

I'm thinking most people wouldn't mind having to boot from SD for a while to get at bluetooth.

http://nookdevs.com/NookColor:_Nookie_Froyo_Technical_Page#Source_Code_the_Technical_Page

Edit: It has been pointed out to me that this question might be perceived as offensive. Certainly not trying to do that. Just curious. Anyway... If it is, I'll gladly edit this post and delete it to oblivion.

Going to dload the nookie froyo project now to compile locally and see what it has.
[Nook Color Android Development] Mikroft:
Not offensive but redundant and not helpful. Working bluetooth is pretty far away at the moment from being usable that these requests are not even feasible.

Like asking. Can you test drive this car for me... when there's no steering, brakes, transmission, seats, fuel, etc. He essentially has to rebuild an entire kernel for this to work.
[Nook Color Android Development] deerkiller11:
Thanks for all the work, whenever you get it done will be soon enough. If I had any experience with this kind of programming work I would offer my help but I don't so I will just say good job and keep it up. When people ask me to do something for free I do it when I have free time and if they bagger me it just takes longer.

Thanks again,

If this helps you, chip TI WL1273 is in HTC legend, and there is source code for kernel on developer.htc.com. Which includes drivers, but I'm not sure if they work without htc framework. So another option is to take source from cyanogen mod, which is free on github, and it is working without htc framework. This chip is also capable of receiveng FM radio, but a think nobody has managed to get it working outside htc based rom.
[Nook Color Android Development] mattphoner:

[Nook Color Android Development] gedster314:
Fm radio on cell phones s#cks anyway. Where I live 90% of the stations are Spanish or Top40 crap. The only station I can stand is the local NPR. I end up streaming all my stuff. So they can keep Fm at the bottom of the list.

Official Froyo devkit available for Download onTI website

--------------------------------------------------------------------------------

Hello.

I am sorry I could not post on the development thread. this is my first post. I have been checking the TI developer site and noticed that they just posted an official android Froyo devkit available for download. the link is:

software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/02_02_00/index_FDS.html

and the documentation is at:

/processors.wiki.ti.com/index.php/TI-Android-FroYo-DevKit-V2.2_UserGuide

The source code is included and has new drivers for the SGX chip and a devkit for the WL1271 including bluetooth stack.

Also the kit include drivers for the DSP for video decoding and Flash acceleration in android.
[Nook Color Android Development] spamftw:
Occip, would you accept a bounty on this?
[Nook Color Android Development] dalingrin:
Hoping we can collaborate on this. I have .32 partially ported as well. I think this will go much faster if we work together. Jump on #nookie on IRC and send me a message sometime if you have the time.
[Nook Color Android Development] inferniac90:
No you don't, any ordinary headphones work for this.
[Nook Color Android Development] RoboRay:
Not when the antenna contact on the chip is not physically connected to the headphone jack. You can plug in anything you want and it still won't matter.
[Nook Color Android Development] Homer_S_xda:
If you guys do start collaborating, can I make a humble request? Google in its wisdom left out functionality for proxy. Can you roll IPtables support into the kernel? Or, some other way, as I took a peek at the CM forums and it looks like some have at least proxy for browser. This is the one feature that is in my stock iPod Touch that I really miss on my NC: the ability to set a device wide proxy setting per wireless connection, including a proxy url.

I believe the BT uses the same antenna as Wifi as same frequency... the antenna I heard that wasn't connected was the FM antenna which usually is connected to phone jack...

You can't just plug in any headphone and just run an app and expect it to work. It needs driver support for it to work where rebuilding the kernel will help.

Set up a donation

@occip, please setup donation for your efforts. The other poster who offered to team up could work with you and divvy the total as you see fit.

There are too many people asking for this or that and should donate if they want time spent on it.

Suggestions to other interested parties: donate $10 now to kickstart/show appreciation, $20-50 when it's working, $20-50 for occip/team to work on something you specifically desire like volume adjustment, IPtables, etc. I'd confirm with occip that they're even interested in looking into this via a PM and time required/reasonable donation.

BT with GPS, HID, audio, mic capabilities would blow the doors off of this modest 'reader'. Money talks, B$ walks

I'm in for $10 as soon as occip has a donate button :D

Disclaimer: I have nothing to do with occip or anyone working on this, just a keen interest in the NC.

Having been playing with this for the last few days I have come to the conclusion that the antenna pin is not connected.

What I think is happening is that the disconnected pin is acting like an untuned antenna itself and that while it is working at a short distance due to wavelength of bt that the swr (standing wave ratio) is so high that its causing the very slow speeds
