The EpicCM7 team needs more information about GPS in the Samsung SPH-D700 / Sprint Epic 4G!
Specifically, we need to know:
What Chipset is used for GPS
What are the GPIO Pin Assignments for GPS on this chip
Where in gpio-sysfs are these located
With this information, Dameon will be able to get the GPS functional.
Without it, we're stuck.
Information gathered so far indicates that we have a Qualcomm QSC6085 chipset.
I've read 2 datasheets on it so far, neither of which deal specifically with its GPS functions:
https://www.droid-developers.org/images/2/25/Qsc6085-audio.pdf
https://www.droid-developers.org/images/3/3c/Qsc6085-overview.pdf
For reference, www.avrfreaks.net/wiki/index.php/Documentation:Linux/GPIO#GPIO_Numbers
Moved to general.
I think this should be moved back to where it was..... This is def development stuff not general
I concur. This needs to be moved back to development. This is NOT something that is general, or that the general public is going to know. It is highly specific to GPIO and gps assignments.

Oops That's what happens when you just see the [Q] and move the thread without reading it. Moved back to development, sorry about that
[Dev-Q] Can clear things up for next time? ;P just a suggestion
Hey guys. I found some links to the documents that you are looking for, but as it probably breaks NDAs since the docs are confidential, I probably shouldn't post them. If you read the overview however, it mentions several Qualcomm document numbers....

A quick google search should head you in the right direction.
Doesn't the milestone and Droids have the Qualcomm QSC6085 chipset as well..maybe get some info from milestone developers as they've been dealing with the chipset far longer?

The milestone uses the same chip as well as the droid x, I believe.
Attached are some screens. Hopefully that's everything you need.
Wheras that may help, I still need the gpio pins used on the epic. There are two we need for interfacing with the gps.

Are you sure the GPS is exposed on the Hummingbird GPIOs?
I haven't looked too carefully, but I imagine that GPS communication is done with the baseband via dpram. At least, there's a ton of GPS-related foo in /system/lib/libsec-ril40.so, and /system/lib/libsecgps.so uses rild.
The GPS and CDMA modem is the Qualcomm QSC6085 used in the Droid X, Droid 2 versions, and the original Droid. It's also used in the Samsung Moment and Acclaim. A few months ago I took apart a Samsung Rant and found the chip in there too.
Thanks, arashed31. I had begun to wonder if maybe Samsung took this in-house, too. All of the GPS GPIO code in the kernel sources for our phones is in Samsung's s5pv and s3pc files.
We've got some tantalizing hints from those source files, but so far have not definitively located the files within gpio-sysfs.
If anyone wants to have a look at the code in question, and maybe provide a stroke of genius, dive right in!

Well which pins are you looking for?
That kernel defines eight GPS GPIO pins, don't know how accurate the are though. Anyways, this should be their assignment:
Code:
GPIO_GPS_UART_RXD: S5PV210_GPA0(4): gpio4
GPIO_GPS_UART_TXD: S5PV210_GPA0(5): gpio5
GPIO_GPS_UART_CTS: S5PV210_GPA0(6): gpio6
GPIO_GPS_UART_RTS: S5PV210_GPA0(7): gpio7
GPIO_GPS_nRST: S5PV210_GPG3(2): gpio122 or S5PV210_GPG3(0): gpio120
GPIO_GPS_PWR_EN: S5PV210_GPG3(1): gpio121
GPIO_GPS_CLK_INT: S5PV210_GPG3(2): gpio122
GPIO_GPS_CLK_EN: S5PV210_MP04(6): ?
Everywhere I looked GPA0 is the first gpiochip enumerated, so those assignments should be right. However they're not exported, instead the UART should be configured as the serial device /dev/s3c2410_serial1 (which is probably what you want).
GPIO_GPS_nRST & GPIO_GPS_PWR_EN do appear exported. The gpiochip enumeration is the same through GPG3 between that kernel and EB13, and on my phone GPG3 is gpiochip120, so those assingments are probably accurate. They should also appear as "/sys/devices/virtual/sec/gps/GPS_nRST" & "/sys/devices/virtual/sec/gps/GPS_PWR_EN", but I can't confirm.
GPIO_GPS_nRST's assigment depends on CONFIG_SAMSUNG_GALAXYSB, I don't know which config you're using so I can't say which it is. Although the "SAMSUNG_GALAXYSB" assignment conflicts with GPIO_GPS_CLK_INT, so who knows.
Here's the thing, GPIO_GPS_nRST & GPIO_GPS_PWR_EN are defined as "dummies" (S5PV210_GPIO_END) in both DI18 and EB13, so they're never used. While /dev/s3c2410_serial1 does exist in EB13, no proceses use it when GPS is active.
If I had to guess, this is leftover from the GSM Galaxy S where the GPS chip might've been separate from the baseband. CDMA basebands integrates GPS, in part, I imagine, for E911 support.
So again, are you sure the GPS is exposed on the Hummingbird's GPIOs?
I guess not. But in doing so they have severely hindered our ability to get the gps working. Its still possible, but its going to prove to be more difficult.

What are you using for the ril?
RIL is using the samsung proprietary crap. No way around that bit for now. The rilj (framework.jar) is using some patches to get our radio working. But the rilc is samsung proprietary.
Sent from my Samsung-SPH-D700 using Tapatalk
GPS is controlled by the Modem(qsc6085) chipset, and it called GPSOne we CANNOT use the gps from the gsm version, the problem you going to need the libhardware.so (samsung) to get gps working

I wont close it as I agree I have not found a 100% sure answer but i am 99% sure it doesnt have the hardware. I also never saw ATT admit that it did, even in the training docs I got it never mentioned it, It was one of the reasons I wanted to hold off getting it.
I also missed the FM radio of my Tilt 2, but I found this item on eBay that gives me pretty much what I want via BT and I can use it standalone without the phone if I want. Bought one about amonth ago and have been very happy with it. Call and music quality are excellent and battery life is better than 20 hours running and more than a week on standby. I also have a pair of Motorola S9s, but I prefer the in-ear style of these for mountain biking. Price has dropped $15 since I bought mine.

I use Iheartradio and Tunein radio for all my local channels and Talk radio. Give it a try.
I would add $25 to get a fully working fm radio with no other hardware.
it might have the hardware as the wifi/BT chip is the same as in the SGS.
The antenna may not be solder on the headphone jack.

It doesn't have FM anything. Period. The device itself doesn't have the physical capability. No amount of coding is ever going to change that.

im not sure that that is true, the old development thread had seemingly knowledgable people that thought at least one chip had fm capabilities.
problem is that without an antenna the chip is useless. if any one knows the hardware and driver coding that's great but modifying for an antenna is a problem. i dont know jack about coding and drivers but i can solder and know a couple clever ways to solder to surface mount boards fairly safely. maybe when i get a substitute for the captivate i can be a guini pig but first somebody needs to see if there are any chips that can support fm radio, if the chip can output to the dac in any way and see if they can replace or edit the samsung drivers and anything else. then if there is some posibility and a dev that will commit themself to the software we can think about making an antenna.
ill put up money if someone decides to take the chalenge. also would like to try a ffc mod but that will require some butchering of the phone, i need an infuse or galaxy s 2 before i butcher the cappy.

The 4751 used in the Captivate has no FM capability. None. Zero. Nada. Those seemingly knowledgeable people might have seemed knowledgeable, but they were speculating. Even the manufacturer states it doesn't have FM.
Broadcom makes a chip with FM transmitter (2076) but this doesn't have it. You can only code a driver if you have the SDK from Broadcom, and you can only get the SDK if you're one of Broadcom's customers (i.e. Samsung). This is a fool's quest.
The antenna would actually be the simplest part: the I9000 uses the headphone cord as the antenna.
If you really want FM that badly, get a $5 radio.

ahh, i re read it, (it's been months since i looked at it) now i see that some models of the galaxy s have a dedicated fm chip si4709 or something. and some have a gps chip that can support fm bcm4329, the speculation was about the bcm4329 chip which is not in the captivate but once the conversation got started about that chip people were dicussing it for phones with that chip and there was little in the thread noting that it did not actually apply to the captivate. somehow it was only mentioned maybe once that the captivate doesnt use that chip. there is no evidence that the si4709 chip is there or properly connected. i must have over looked the model gps chip they were discussing last i read the thread.
and yes i know many devices use the headphones as the antenna the problem had there been a fm radio chip that was hardware disabled would be esablishing a connection to the headphone jack. knowing where to put the wire is one thing. soldering it in there is another. you cant just use an old soldering iron on these things.

We'll my phone has a so-called bad chip and I've had it since April (over six months) and it's still up and running, you just mustn't do daft things like pull battery etc....although I did that many times, before the community discovered that it was so risky!
There are guides on what best to do, in order to avoid the chance of any issues!
If you did "fry the eMMC chip" there is still some possibility of a warranty return.
Is there actually any evidence that it is a particular type or brand of eMMC chip that causes the problem?
My engineering experience would lead me to also look for a weakness in the design of some associated circuit (i.e. locking out write ability to the chip when battery voltage is below usable value).

Yes if you look here in the forum you'll find the names of the bad chips.
I have located a cg2900 driver that may have already been seen and may or may not be useful. My cursory knowledge of kernel source tells me it might provide insight or even provide a complete swap of the current driver (with its bluetooth issues).
If it has been looked at before and/or is useless...I apologize. Just tossing it out there on an off chance.
http://code.google.com/p/ast-linux-...e6394ac1716735f510df24873fbbf2#staging/cg2900
*Bump*
Does anyone have the knowledge to know if this will solve our bluetooth issues?
Nope won't really be much help. There is a reason the driver is in "staging". Its never been finalized and accepted, and on top of that, Samsung used a version that was submitted to the kernel mailing list, and vehemently rejected before this version in staging. They are no where near alike so making comparisons between the two is a nightmare. I've even tried switching in the driver from the snowball, the ref board that sti made with the cg2900. It uses the bluez stack so i had high hopes. To no avail. Have never been able to get farther than where it is without completely hosing GPS.

I ask this here as I've already asked on the Samsung Galaxy S3 forum with no answers. I'm guessing there are more teccy types here! Okay, getting p*issed now. I have a brand new Samsung Galaxy S3 and my friend's HTC One S is FAR faster on the internet than my handset. Both handsets came from 3UK (network locked & branded) on the same plan (The One Plan). The tests were done with the same sim so it's not the sim card-definitely the handset. Also, of course, they were done in the exact same location at the same time.
My previous SGS2 compared like my current handsset with his HTC but I assumed that was because the HTC had more up to date components and getting the all new SGS3 would solve. Obviously not!!!
I have looked at the settings and I can't see anything I can change. Can any of the wizards here shed some light?

Look, dude. Your browser's speed is a combination of three things.
1) Hardware - including processor, memory and radio/modem.
2) ISP - This speaks for itself
3) Software - Poorly written software will load and display a page slowly. Herein lies your answer, I'm guessing.
Root and flash away. That's how you fix that.
I own neither handset, but basic logic leads me to this conclusion. That said, I may be wrong.

I would test accessing at same place, same time on the same Wifi and using same browser to get a baseline. Testing on mobile signal is just too unpredictable.

Both of these people mention key points about your data speed tests. Testing two different devices that are performing the same task is about all those devices have in common. You need some intersecting properties between the two devices. Yes, their os may be the same but are they even running the same version? They are different makes, HTC vs. Samsung, using different browsers plus more.
You can test over and over to see which comes out on top. But you won't know why until you find out what the differences and similarities are between the two devices to see why you're getting the results you've been getting. Hope this helps.

Hi guys, i wanna buy an used p6800 but for some reason it dosnt support any kind of simkards and i need to use 3G internet on that, is there any solution like using an external 3G dongle for using internet on that?
thanks...
If you have root, you can try PPP Widget. Just add it to your homescreen and give root access.
I personally haven't tried it because have no USB dongle.
Website and FAQ here : http://www.draisberghof.de/android/pppwidget.html
Download here : https://play.google.com/store/apps/details?id=de.draisberghof.pppwidget
Although their website says Android 3.1 and up, during my kernel development I have seen gitHub source changes for PPP Widget support. The source could be for increasing USB power (edit : supply current mA) for the dongles to work from tab (properly) without an external supply. Can't remember.

Hmm... AFAIK, don't think installing PPP is enough to get 3G USB dongles working with Android if the kernel don't provide 3G USB dongles drivers... ^^
That was possible with the ASUS TF101 as a dev provided a 3G drivers pack for HC but can't remember if this pack is still compatible with ICS (compiled for NVidia Tegra 2 SOC)...
And why Samsung would do this with a device supposed to be 3G ready ???
Then, do you have experience in developing such drivers pack with no USB dongles to test on ???

I did make mention of kernel source changes, just couldn't remember exactly what. Seems like a waste of time for a 3G device, but OP sure to have a reason.

Of course, let OP buy a 3G USB dongle he won't be able to use it as he won't find any driver and the such, making this USB dongle simply useless...
I guess if he buys a used P6800 with a failed internal 3G part it's because he doesn't have much money to waste.
I already know the literature about 3G USB dongle uses and no need to talk about the OTG capability of the P6800 and the "juice" this device is capable to deliver enough power for the USB dongle...
He will need an unlocked 3G USB dongle with a driver he will have to find and compiled by himself, a precompiled "option" module, a precompiled usb_modeswitch specifically for the Exynos with the big APN database (usb_modeswitch.conf or usb-modeswitch-versions.xml) unless he knows exactly what APN to enter, finally and probably a modified kernel AND a very good tutorial to teach him how to set all this up, including the AT commands and such !!!
And we don't even know if he needs CDMA or HSDPA version depending on the provider and the Sim Card he has or will have, nor in which countries he is living in... ^^
On the other hand I suggested a universal independent self powered 3G WiFi Hotspot Router he could use "out of the box" with any equipments such as smartphones, tablets, PC, for Android or Apple iOS, etc... for his past, present, or future uses...
For the literature about 3G USB dongle uses, start here (just for samples, but Google is your friend including XDA forums of course) :
http://freedune.wordpress.com/2011/06/23/success-with-usb-3g-modems-on-android/
and the well known draisberghof.de website (which also provide the PPP widget for Android), even though this is related to Linux, the principle is the same for Android as all tools have to be recomplied accordingly :
http://www.draisberghof.de/usb_modeswitch/
For the universal self-powered 3G WiFi Hotspot Router, there so many, starting from as low as $16 to over $200 (LTE version) depending of the quality, his needs and the money he can afford to pay for...
Just some suggestions as samples of what is existing on the market... I used Amazon.com to be simple and to offer an idea of what exists, but he may have to use his local retailer depending where OP is living... :
http://www.amazon.com/Wireless-Broa...5&sr=8-9&keywords=3G+WiFi+Router+hotspot+cdma
http://www.amazon.com/17597-Unlocke...&keywords=Huawei+E5331+3G+WiFi+Router+hotspot
http://www.amazon.com/Unlocked-ZTE-MF60-GSM-Wireless/dp/B005IDLYK4/ref=pd_sim_sbs_cps_6
http://www.amazon.com/Huawei-E589-Pocket-WiFi-Router/dp/B00ALSYTK8/ref=pd_sim_pc_5
Now, he can make his own decision with the good informations...
EDIT : forgot to mention : whether OP uses a 3G USB Dongle or a 3G WiFi Hotspot Router, he won't be able to place a phone call BUT just for Internet data access, unless stated otherwise... ^^

I see you've replied to the wrong user. ?
I did state that I have no time for the matter (or indeed further interest) I am unable to further assist or suggest.
I'm sure the info will be of use to the OP though.....
Edit: sorry, forgot to hit thanks anyway .cheers :thumbup:

NOPE, the answer was intended to both of you including to OP...
You suggested him to install PPP to be able to use 3G feature (with internal 3G or external 3G USB dongle ???)
I just confirmed YOU it wasn't that simple as I think he misunderstood your first previous answer...

Well you wasted you time with me, sorry. Please read replies more carefully. I KNOW it's not as simple (or probably) as it is, but sometimes you never know with newer firmware what is supported and what is not.... Like external HDD support, just enable in kernel config and compile.
