@GliTCH82: It will be difficult & require practice on simular chips in one of your old phones first. The biggest problem, however, is that we would have to provide a LNA circuit which would draw power continuously. gpogge thinks about 20mA. That's a lot and would further shorten battery life on an already power challenged device...

@Des: Fortunately, we don't need to resort to that method. With pinouts in hand we now know the facts. Qualcomm seperated GPS LNA from GPSMix to allow design flexibility. HTC disabled the LNA to either prevent chip damage from floating inputs or decrease power draw. There's no one pin for the antenna as the block diagrams hinted at I'm afraid.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Cuivienor:
Are we getting to the point that a Bluetooth GPS is the best choice, and that hope to add an antenna just became nil?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Sleuth255:
Pretty much.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Izzard-UK:
Well someone should still complete the hack, so that at least one Hermes with GPS built-in exists ;)

(No, I'm not offering mine, hehehe)

I'd go for this for sure, but the LNA power draw issue may be a show stopper. I need battery life more than GPS on my Hermes. Maybe I'll do the 8525....

GPS Antenna models

Hi everyone

Just got my phone about two weeks ago and been reading these forums with great interest.

Got some thoughts on the GPS mod, would it be possible that some brands have the antenna while others don't. Have you tested more than one brand?

Secondly would the GPS receiver on these phones have a manual gain control, eg can it be programmed to boost single, a lot of hardware controllers have registers for doing these things.

Any way might be repeating some one else, but thought worth mentioning

Cheers

Super-Mega-Ultra Confused.

I have been reading a lot, every trhead i found regarding GPS on the Hermes, and I have no conclusion.

I have a Cingular 8525 Bought Yesterday and i have a Cingular 8125 as well (not for long)

Can anybody please bottomline this for me? I there any software-only upgrade that i can do on my phone to get my GPS receiver working? I am not gonna take ti apart bc i am not a developer, just an advanced user and a networking guy.

Thanks a lot.

Interestingly though if you look in the comments at the bottom the guy says he has managed to get a fix, although more often than not he never gets one. I wonder if it was actually an accurate fix? If all Hermes are created equal then surely not, but if some have different hardware then HTC might have changed some things around in there.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] JR_de:
Well, my French is as good as my Cantonese or my Swahili but just the fact he didn't post any pictures which proofs that he had a fix is enough evidence for me to assume it's not working.

But a question I have in mind: the GPS does not work, but why they have put the icon of the GPS (yes, hidden, but there is)?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] tadzio:
The program behind the icon is a com port splitter. It is useful for Bluetooth GPS mice, but it's not a GPS application per se.

Alright for those of us who know how to use the phone but arent very good at the technical mumbo-jumbo basically the final conclusion is that there is the software for built in gps but not the hardware so in essence there is no built in gps in the htc tytn/hermes
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] tony.wheeler:
I think you may be wrong. The GPS icon in settings just allows you to configure the way a (eg Bluetooth) GPS device communicates with the device (comm ports and data sharing via WM5 etc) - this is more of a driver capability. The TyTn does have a GPS receiver and some on these forums have been able to get (hacked) software to communicate with the GPS chip. The problem seems to be that HTC (the device manufacturer) have not installed an antenna so no signal can be received.

It may just be that HTC bundle chips such as the GPS one together on device boards to save money at the manufacturing stage - hence the chip which cannot be used...

So the TyTn does have a GPS but unless somebody comes up with a way to integrate (or connect) a GPS antenna we will never see it in use.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] crazyC:
Tytn has GPS chip, but not only is there no antenna, but it appears HTC have effectively disabled part of the setup (to save power etc). Fixing it would appear to require some very specialist skills and not be economically feasible except for a one off 'because you can'.

Hi guys, very interesting topic

As a former owners of motorola agps devices (A925, A1000) i have some experience with the agps on phones. There is a MAJOR difference between PDA gps and phone gps in terms of antenna. As far as i know, all gps phones have gps antena INTEGRATED in phone antenna. This means that the gps signal acquired by internal antenna is very poor (the same on A1000, A925)

Practically, in order to get a lock from GPS on A1000 i had to do the following:

find a big open space (like a park or a field) with clear sky (without any cloud)

and waiting up to 45 minutes for a lock.

And, agps solution try first to find the gps coordinates from cell network if there are provided. If you boot up your phone and imediatelly get gps coordinates these for sure AREN'T from sattelites but from the cell network (probably this explains why you receive coordinates from 4 satelites)

Please, before soldering and mess up your phones :) try this procedure

I'm waiting for your results and up to then i will try to enable the gps on my new HTC tytn :)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] trashcan:
Sicne you alrady have a tytn, you could try this yourself and show us the results:D
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] bau33:
you are right but since a just have the tytn for a week and is a bootloader 1.04 and a radio 1.06 first i have to know the device better in order to update the radio rom. with some help maybe i can make a quick upgrade to radio rom 1.24.01. Unfortunatelly, even i read a lot of posts is not very clear for me if i can just put the new radio upgrade and everything will work or i have to make an entire rom upgrade for the device

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Shadowmite:
I'm just curious about one thing in this thread, the methodology used sounds solid. However the conclusion you all came up with doesn't seem to me to match the details of the experiment. You say the inputs for the antenna are grounded... Yet the experimenters found that they could pick up very small amounts of signal, this could not be possible if they were grounded. Am I missing something? From my current understanding are you saying that the preamp input is grounded? The final stage is not?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Sleuth255:
Confirmed with Qualcomm at MEDC Shadowmite. The GPS portion of the RFR6250 has been deliberately disabled in Hermes. The technical gps thread has the relevant info with hi-rez pics of the affected components.

The initial findings ??

In the start of the thread Saar Avigour wrote :

Guys IT WORKS... to all those unbelievers... I've upgraded the ROM in a chinch, installed IGO 2006 and with trembling hands activated the GPS:

1. Fix was almost immediate

2. Sat. discovery was beyond expectations - 7 Sats

3. Almanach saved (meaning next GPS off/on got me immediate fix)

4. GPS Accuracy (DOP) = 1.2

Now all unbelievers, eat your hats.

All remaining is to adapt DOPOD ROM to our Hermeses. Let's see now what we can do here.

============

Saar

This was with a ROM from Trinity, which made somewhat useless the device as far as I understood, but still he was able to pin 7 satellites, so surely hardwarewise this should be possible, or am I missing something.

I have read the full thread (I promise) :-)

Or was that also a Trinity used there ??

Guys, READ THE RELEVANT THREADS. Both the GPS Technical Development thread and the other one, easily found if you search. There is compelling evidence that the GPS chip is disabled in the Hermes and there is no possibility of attaching an antenna or anything else to make it work.

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Oliy:
If you read all of them, you will know that the problem is:

The GPS chip is present but the antenna connections have been shorted together, meaning that in order to get it to work you have to lift the pins of the surface mount chip and attach an antenna.

If you manage to do this, the software is pretty much already available to use it. However, there are a lot of electronic engineers (myself included) and technicians on here who believe it to be beyond their skills, so if you think you can do it by all means try, but be prepared to buy another phone to replace it when you try!

GPS enabled radio ROM for Hermes

Here is the 1.29.00.11 radio from Trinity's ROM, encoded in NBF format so it is possible to flash in Hermes devices. As sun75 proved in a comment above, it is possible to enable the GPS from the radio AT command interpreter!

Hermes_GPS_Enabled_Radio_1.29_EXPERIMENTAL.rar​

I will try to extract the needed dll and registry settings from Trinity's ROM and do some tests to see if we can see it from WM5.

Those willing to try, be warned this is still very experimental.

Some things you should know about this radio:

It contains HTC_BOOT V1.0108, this radio bootloader doesn't allow to be downgraded, if you flash this radio on your Hermes from now on you will only be able to flash radio ROMs in NBH format (full ROM) when running bootloader 1.09, so it is highly advised to flash this only on SuperCID devices using bootloader 1.04.

Procedure to change the radio version after this radio has been flashed:

1) Device must be running SPL-1.09 (either loaded with 'lnb' command on 1.01-MFG bootloader, or by flashing a full ROM containing it)

2) Flash full ROM which contains the radio you want to put on your device

3) Flash SPL-1.01 MFG

4) Flash ExtROM, and OS in *.nb format as you wish.

I will write a wiki page with this info when I have some more time!

EDIT:

IF YOU WANT TO TEST BETTER USE THIS ONE (HTC_BOOT 1.0107):

Trinity_GSM_GPS_ENABLED_radioROM.zip​

This is a bit safer, the 1.29 is not advised to use...

Sun75, how were yu able to get the NMEA stream? it looked like your GPS was responding so please describe what did you do.

It also looked like what we call a "factory reset" which means that the GPS was just initiated. This is ok and if you will let your device a clear line of sight to the sky it will probably aquire satelites within 1-2 minutes.
