NFC 125 khz - Galaxy S 4 Q&A, Help & Troubleshooting

any idea if the broadcom chip in the s4 is capable of working on the 125khz band? it looks like most nfc is 13.54mhz but i have some HID ProxCard II key cards that i would like to clone. i cant get it to pick them up but i was hoping that if the chip supports the 125khz that it could be patched to work. details about nfc stuff seems to be pretty scarce

Did you find an answer to this? I have some Flexpass cards I'd like to clone.

Wlan for Pharos (Some common features of all OMAP 850 phones)

I thought it was so strange that when I scanned for bluetooth devices I picked up my (pc) internet modem (which is wireless enabled) so I thought bluetooth and wifi must share a lot of the same characteristics.
I was browsing for the latest Android developments and stumbled on the following
Please take a look at this page http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12000&contentId=4679
And this one http://focus.ti.com/general/docs/wtbu/wtbugencontent.tsp?templateId=6123&navigationId=12019&contentId=4635&DCMP=WTBU&HQS=Other+OT+bluetooth
This seems to mean that FM Radio and WiFi is a standard feature of OMAP 850 chips and (for the touch owners look at this page http://focus.ti.com/general/docs/wtbu/wtbugencontent.tsp?templateId=6123&navigationId=12028&contentId=4636&DCMP=WTBU&HQS=Other+OT+agps)
Seems If you have Bluetooth you also have wifi and possibly fm radio built in only lacking the drivers (no special wifi antenna is used in the omap 850 solution accoriding to TI)
It would seem that all we need is the right drivers and regsettings (so no new rom or radio rom should be needed)
Who can make it a working cab?
Woooooooooo!
Good news.
great job
if some solution, make me to buy one.
by the soft solution, strange story !no idea for none cost effective option. why do HTC designers make a 2008 PDA with no WiFi Option!
wow
wow...it might be dream come ture if it happens....please some body develop a driver for pharos Fm radio n wifi.....please buit up some regsettings......
This is a good information. Hope that we could make it work on our Pharos.
Good News... I hope who will make it soon because I don't understand about ARM work.
That is an awesome find man. I hope this info is used to get a wifi working ROM.
I thought it was some kind of cost saving to not include wifi, i.e. some missing hardware. If it's just a driver, that is the so friggen stupid! Why have such a great phone and then neuter it by taking away wifi? And the price is still just as high as the Artemis when it came out. The lack of wifi is the only thing that would keep me from buying one. Otherwise, it would be a great upgrade phone for me since I don't need nor have 3G with my service and and it has the cool flush screen that I wish my Artemis had.
someone knows if the touch dual then also could have the wifi option turned on by drivers? the touch normal has wifi, so i guess it should be possible.
anyone tried the drivers from the htc wizard? it also has a ti omap 850, so driver from such a rom could be coocked into the rom of other devices.
@VOODOOS!L
The touch dual uses the Qualcomm 7200 chipset. That chipset uses the arm926tesj as a co processor but i dont think its the full OMAP 850 chiset.
but there is a project for enabling niki wifi (started out as a project ot enabkle both wifi and gps)
@shawndh
Phone manufacterors do it all the time. Look at the Kaiser story, yes they have some great graphical chip (would be too expensive to make a different chiset with another graphical chip) so they just didnt include the drivers for it.
With some other phones like the touch HTC disabled the wifi in the radio rom... maybe some techies here could try to put an artemis radio rom in the pharos... but for none techies this would probably be an instant brick (thats why i didnt try it) tom_codon maybe you could say something about this....input would be apreciated.
Come to think of it, I remember that they had a crippled GPS radio or something in the TyTn I. The only reason I could think of for disabling wifi is so people who need wifi would buy the the Artemis. To be honest, if I had a choice btwn the two, I would get the Pharos over the Artemis if they both had wifi. Even so, it should still have wifi.
This ia a good news.
I'm waiting.
you know what... im giving up.
ive tried pm ing some guys working on the wifi on nike project, asking tomcodon. no response as yet and prolly not going to get one.
And tried to get qtopia and winlizard(gizard) working.
but in the linux world up is down, left is right, and smart is stupid. those people are (in dutch: contactgestoord) communicationally challenged. you cant find anything on their sites. there is no(or very little) documentation on how stuff works ...noone explains anything... so in order to learn linux you have to know it.
thats why m$ can afford to be so sucky: their competition sucks so much more
i said to the guys at irc #linzwizard hey thnx for the build, i can boot it too (gizard aka linwizard 0.3.0) but the touchscreen driver crashes.
he then said make a support request at sourceforge which i did (btw it isnt obvious how to .. it should be very simple. but hey... thats the linux way, isnt it) response was.. and this is a shocker.. your touchscreen driver doesnt work(.... grrreeeaat) you should disable it...(no description on how)
up for the rom with wifi for the pharos!
Thanks
Not to rain on anyone parade but from the first page from TI, it looks like to get wifi support you have to have a special chip in the phone(upper left corner) thats diferent that the chip to get wifi, so unless someone knows for sure that the WiLink chips are present, I think we are without wifi
Wait and see...
The only problem is... How long does it take to finalize such a ROM?
If it takes 1 yr, for example, I think I will have already changed to at least TouchHD..
Anyway, good news!
Hello! I have a HTC Pharos for one month. Yesterday, i accidentally have wetted phone by tea, and then i disassembled it for cleaning. Cleaning was finish sucсessfully, now phone is working
During disassembly of the device I have made some pictures. I think Wlan module is in the device. Look at the photo! Motherboard have many connectors for external antennas, and Wlan connector is on the board!
http://www.flash-remont.narod.ru/pharos/pharos.jpg
thank you for the picture, its in a good resolution! but what would have made it more clear is if you would have looked for a specific Texas instruments chip with letter combinaton BRF or BL (there are 4 chips mentioned with a dual solution BL6450 BRF 6350 BRF6300 and BRF6150 last one is not good because its a bluetooth only chip) we should also be looking for TI chips with a WL designation and number 1271 1273 1251 1253
at least (BRF6300) - Bluetooth specification v2.0 + EDR single chip should be in the Pharos since we have that bluetooth spec.
in the picture i can make out the TWL3027 chip with extra designation BZQW (at least i think its that chip ... according to the ti site that would be the baseband chip but it doesnt describe on the site what the extra letters mean)http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12311&contentId=4706

hope this is readable since i have a hangover
Kostyan could you post the other pics you made of the interior of the Pharos

Maybe this iron box is Wlan module?
http://flash-remont.narod.ru/pharos/pharos2.jpg
I may open this box, if it is requires for this research
And on this picture, front side of device it is found Wlan antenna? (if overwind board, supposed Wlan module with connector correspond (matched) to on position with Wlan antenna, and it connected with module)

[Q] FM Transmitter?

I was wondering if it is possible to use the FM chip in the phone and use it as an FM transmitter (like the n97)
I'm interested in hearing your thoughts.
Basically no.
For a start, you'd need a chipset capable of transmitting via FM as well as receiving. Just because you can do one, it doesn't mean you can do the other.
Even if the chipset is capable, for it then to work, it'd need to have the necessary drivers installed, which is maybe doable.
It'd also then need an antenna attached to the transmission pin-out on the chipset, which is extremely unlikely to be in place.
So technically it might be possible but in reality it's not - unless SE just happen to have built a fully-functional FM transmitter into the Arc and just forgotten to activate it...

FM Transmitter BCM4329

I think we have a chance to activate the FM transmitter in our phones..
At least we should give a shot?
The BCM4329 has FM Tx & Rx abilities. The Rx part is not used, but maybe we can use the Tx part?
Unfortunately, google doesn't help a lot.
I know that our galaxy S i9000 uses a Si4709 chip for the FM reception, so that's not good for the transmit part.
does somebody have any useful info about this?
i would definitely do everything i could to make this work. this should be the biggest hit feature...
this is a problem for me too.... amy someone helps us...
That was discussed a long time ago without any progress.
Apparently we can't use the FM transmitter if there is one inside SGS
why can't we? what does stops the devs?

First it's not easy without manufacturer's cooperation to have access to the chips and phone documentation, so how to create the drivers drivers ...
Secondly don't even know if physically it could work (for example the transmitter would need a antenna...).
i think the problem was no connection of some pins of whatever - use search option
the antenna issue i think it's not the most problem, I think the not connected pins is more complicated if that is true.
FM transmitter could be nice, but like it seems Samsung probably didn't connect the relevant pins for transmitting audio.

[Q] which wifi chip does this have?

I know the package is the Azurewave AW-NH665 but there's no data sheet published for that. I'm hoping it's got at least a BCM4330 in it. Also hoping for BlueTooth 3.0.
someone who has one check your system/etc/nvram_nh665.txt
it should have info on the wifi chip.
Thanks.
bump
Well, I can tell from the kernel it uses BCM4330 chipset. That should mean b/g/n, Bluetooth 4.0+HS, and FM...
BCM4330.
I'm hoping to connect an FM antenna. See my sig.
AzureWave does other Broadcom modules too.
I don't have one but a dump shows:

Nice, just checked out your radio app. Would be very cool to get that working on the N7. Interestingly I noticed that although that firmware is present, the kernel is actually configured to use:
/system/vendor/firmware/fw_bcmdhd.bin
Not sure exactly what the implications are of that yet.
There are 3 identical files, size 209,175 bytes, and they are for the WiFi core on the chip. Bluetooth and FM share a seperate core.
fw_bcmdhd_apsta.bin
fw_bcmdhd.bin
fw_bcmdhd_p2p.bin
brcm_patchram_plus is a Broadcom proprietary replacement for hciattach and it loads the bcm4330.hcd file. I'm 100% sure because my FM app can do the same as brcm_patchram_plus.
The top of the HCD file contains: "AZW Module665 BCM4330B1 37.4 MHz Class 1.5 ExtLNA"
-----
There is not a single, easily available non-obscure Android tablet over 5" which supports FM. So if possible, even if it requires some hardware mods, the popularity of Nexus 7 will make it compelling for the combination of Android tablet and FM.
Further, FM transmit on Android is virtually unheard of. With access to the transmit antenna pins, this might be possible. There are LOTS of people who don't care about receive, but want transmit to their car stereo.
I expect to see a good number of hardware hackers looking to use the Nexus 7 as a built-in car/entertainment device.

Question about NFC RFID Emulation

I've looked all over for detailed information on smartphones NFC feature and it's ability to emulate an RFID card, but all I keep turning up is very generic information and can't find anything that really digs into the technical specifications and limitations.
This being the one stop shop of all things Android, it seemed logical to try here first to see if anyone might know more that the basic grab regurgitated over and over everywhere you look.
What I have managed to glean from my scouring is that NFC in smart devices operates at the 13.56Mhz range, which seems to be the standard for RFID chips available today. But apparently there's also another group of RFID chips using a much lower frequency of 125Khz and this is where I couldn't turn up any relevant information.
What I'm wanting to know is are the NFC devices backward compatible with the lower frequency? If not is there any sort of chip that acts as a bridge between the two bandwidths that would allow a newer device to communicate with an older one?
I guessing from the lack of info that the answer I'm looking for isn't what I'm going to get, but that's why I'm here, to find out for sure one way or another.
The long story made short to this inquiry is I have a aftermarket device that adds push to start feature to an otherwise ordinary keyed ignition automobile that uses RFID to enable the ignition system, but as I've uncovered it's using the 125khz frequency, that I very much would love to find a way to use my oneplus 8 pro's NFC functionality to be able to operate.
So is there any way I can make this work or am I just SOL and short 2+ hrs of my life for not just coming here first?
