quick q's about MSM7201a chips' gps

is it possible for phone that uses MSM7201a to remove gps only?
in korea, they recently launched lg incite phone with MSM7201a, but gps is not included. but i thought it wasn't possible for you to remove gps ability from MSM7201a. anyone has the answer?

Yes, it is possible. Producer can not add pinouts for gps, can not add gps antenta to phone, etc. And also GPS module can be blocked itself.

thats really the main difference between the HTC hermes and the trinity. in the trinity the gps antenna is connected

so it that mean that gps chip is there but its just not connected? or is that mean they just took the gps module? cause what i've heard was that gps chip s can not be removed in MSM7201a

Yes, that is mean GPS is there but you can't make use of it. Few pda's have MSM7200 processor without GPS capabilities - HTC Touch Dual, LG KS20 etc.

[Q] External GPS

Has anyone experience with the connection of the galaxy with a bluetooth GPS ? My car's windows are provided with a heat shield made of a metal film, i can only use a bluetooth GPS in my cars GPS windows.
I would use Sygic.
I'm now using a HTC Touch Pro WM6.5 and it works fine with a Bluetooth GPS
I contacted Samsung with my question but the only answer i got was that i had tot contact route 66 ???
The bluetooth GPS is for me the point to buy a galaxy or not<;

Don't buy any android phone, far as I know, bt gps not supported on android. May be some workarounds for specific programs.

Its a pity that android does not suport external gps.. I'd like to use that too. (I just got a Galaxy S).
I think the galaxy S has a socket for gps antenna on the back (under the cover).. so you can at least try to plug in one of those 5€ ebay gps 1.5ghz antennas to improve signal. Just put the magnetic box on the roof of your car.

As I've replied in the GPS Poll thread, I believe TrekBuddy supports external GPS just fine, so I wouldn't think it's Android limitation rather than a choice of the programmers of most apps - IMO they just don't bother supporting external GPS when there's not a single Android device that doesn't have internal...(I guess).

I guess you got a point when you say that all Android devices have a gps chip embedded. But I sill think it's an Android limitation not supporting an external gps.
On Symbian devices, you just have to say 'use bluetooth gps' in your application once you've paired it.
In WinMo the internal gps has a com port, so does the external when you hook it up. Again you tell the gps software which com port it has to use.
This kind of association does not exist inside Android. You can hook up a external GPS, but no program will access it. The OS itself doesn't have access to it.
BTW I looked this up, but I could not find what chip goes inside the SGS. Is it SirfStar III? Can anyone confirm?

It is a Broadcom BCM 4751 chip. Designed on a friday afternoon, after a long, well-wined lunch. Or so I heard. But I hear a lot of nonsensical rumours.

Beowulf_pt did you manage to redirect data from external GPS?
I can read data with "bluetooh GPS" aplication but i did not find any redirect software.
I have a Hollux receiver that say's 10 satelites in use rather then 8 of the galaxy.

You got me wrong. I'm not trying to use the BT GPS with the SGS as that is currently not possible in android. No native stack support nor navigation apps that use the units over the internal GPS. Only that little experimental app that reads NMEA data but has no real use. I hope Android gets this in 3.0 but I doubt it.
What I will try to do with the Samsung is to connect it to an external amplified GPS antenna (1.5 GHz) via the connector on the back of the samsung (net to the SIM card).
I have not recieved the antenna yet so I can't comment... but it should at least provide some better SNR results.
PS: I also have a Holux. It is quite nice, I use it a lot with my Nokia E72 and it works fine unlike the SGS

I can understand their decision not to invest time in this as all android devices have an internal GPS... but time has proven that that is a bad idea as many units have really poor GPS. The Galaxy S is probably the worst of them all.
Without the ability to use an externa receiver you're pretty much screwed... no alternatives at all.

Guys,
Did any one try this app ?

The free version is a trial, it disconnects every 10 minutes or so. The full version is 1.99€.
I tried the free version with two of my bluetooth devices (Holux M1200 and ncs-navi 150), seems to work fine with both.
BTW, with JM7+voodoo fix combination, the internal GPS has been quite satisfactory so far (touching wood...)

Has anyone experience with this application yet ?

Bluetooth gps seems to have a bug. It seems to update it's location and after that sgs will give its location, what happens is that it starts switches between the two locations every second
If you turn gps location service off from android settings, the lag is gone.
However, an app named "gps provider" does not lag in the same way. I think bluetooth gps mouse app will have updatea, where this problem will be fixed.
Other than that the location is very precise using an Nokia LD-W3 bluetooth gps.

i'm using the bluetooth gps mouse with sygic mobile maps and it works perfectly. I did'nt hope it was working that nice.

What you mean with "quite satisfactory"? Does the internal GPS get a fix without A-gps support? I mean without being online?
I use GPS Bluetooth mouse unlimited on a daily basis with Motonav , Sygic or Navigon.
Internal gps receiver AND Mobile networks( A-gps) are disabled on my sgs.
My external gps receiver got a sirfstarIII chipset . In a hot start I get a fix in less than 20 seconds. Otherwise 4 to 6 minutes in a cold start.
Once again no need for internal gps receiver and / or A-gps (celular network) for for a fast and stable satellite fix. Pure GPS navigation pleasure...
Offline GPS navigation = Freedom
And it rocks on my super-Amoled gs screen!!!

*Capacitive, 4-point multitouch screen with WVGA (800x480) resolution
*DirectX9 rendering-capable GPU
*5-megapixel camera with flash
*FM radio tuner
*Accelerometer with compass, ambient light sensor, proximity sensor and Assisted GPS

Those specs look wrong. It's got a snapdragon and 576 ram.
http://www.htc.com/uk/product/hd7/specification.html

The chances of HTC NOT using the same wifi/bluetooth/fm chip they've used on their past phones this year are very slim.
Meaning, fm tuner is built in hardware wise.

I think you'll find he posted the minimum specification requirements set out by Microsoft, and so no Windows Phone 7 should come without FM Radio, but what do I know - I haven't got the HD7.... yet.

So can any owners confirm if it has hardware fm radio and not just internet radio please?

The HD7 DOES have FM Radio it can be found under the Music & Video Hub

You do need the headphones pluged in though

yeah fm wont work without headphones, says
"No antenna
this phone uses your headphones as and FM radio antenna, To listen to the radio,connect your headphones."

FYI you don't need to plug in headphones to listen to the radio on loud speaker. you can also just plug in any kind of adaptor (without the headphone leads) such as a headphone splitter and it will still work.

ummmmm snapdragon is a scorpion / A8 core
secondly those are MINIMUM specs, 256MB is the MINIMUM not required
thirdly, MS requires this for the Zune application. It's a common basic feature of the OS, it has to have an FM radio in it.

Can you use a stereo bluetooth headset with the FM receiver?

Great question - just tried and No, you need to have 'something' plugged into the headphone jack so that the phone thinks there is a cord to use as an antenna.

[Q] FM Transmitter

Most references I see to the chip in the Galaxy S for handling the Bluetooth, WiFi, and FM are listed as a broadcom. I was unable to locate a chipset on broadcoms site that lists support for Bluetooth 3.0, but I did notice nearly all of the broacom chips that support FM radio support it as RX and TX. Is the chip in the Galaxy S a broadcom, and if so has anyone found a way to enable the TX portion? It was more a curiosity question as I'm sure the TX power is low as is the sound quality, but hey if it does offer it, why not exploit it?
Maybe this has already been answered for the Samsungs and I just missed it in my searches. The searches only returned other brand/model phones.
The other question I was wondering is if the FM range is hard coded in the chip, or if it's a soft radio where the RX frequencies could be shifted to say the Weather Band in the US, or some other area near the normal FM radio range? Again, this is all more out of curiosity than anything.
Edit>
I found this one that supports BT 3.0 and still lists FM RX/TX
BCM20751 - Bluetooth® + GPS + FM Combination ('Combo') Chip Solution

Well, this is like the only thing I'm missing from my old Nokia N97.. So I would like it.

Well, after looking at the Samsung source for the I9000, it appears they use the SI4709 chip for FM reception, and that chip doesn't support FM TX, just RX.

[Q] Has anyone got a ANT+ heart rate monitor working with any apps?

Hi,
As the questions says, I've got a garmin heartrate monitor working with the ANT+ app but I can't get any other app to see it (mainly runtastic pro) - wondering if anyone has any success with it?
N.

I might trying updating to the latest firmware, currently on 14.1.g.1.518.

I've got a Garmin monitor, and a PowerCal monitor running with IPBike. I tried to get the Garmin Fit app working but there's no option to add the sensors.

Iam using My tracks and Garmin heart rate monitor.Works well.Dont forget to download and install ANT Radio Service.

Anyone using ANT+ with anything but the stock ROM?

I'm using rooted stock rom(NUT .757), but ANT+ is not working.

Oh no that is a nightmare. Maybe I won't be upgrading then!
I'm on NUT's .136 and ANT+ is unreliable but just about works. For example when I run an ANT+ app, the bluetooth icon appears. If I close bluetooth, ANT+ stops working! Both bluetooth and wifi continually switch themselves on without any intervention from me on this ROM. Anyway, the ANT+ often mysteriously stops working during a (bike) ride and I either have to toggle bluetooth on and off (twice) or reboot to get it working again.
Good luck, I do not think many Android devs are also fitness orientated.....

Doh, you cannot turn off BT, that's how the ANT+ works on the device.

Interesting - I was using my Samsung Galaxy Nexus with a ANT+ dongle which did not exhibit this behaviour i.e. I did not need bluetooth to be switched on to enable the ANT+. And my understanding is bluetooth and ANT+ are separate radios. Do you know different?

That because Bluetooth and ANT+ are integrated in the same Chip so you have to enable Bluetooth to let it work. In Samsung probably they are separated. Many Manufacturing use different Chips Radio so some can have this behaviour.

I recently upgraded to the latest (4.4.2), lo and behold bluetooth is not activated when I use ANT+

That don't mean Bluetooth and ANT+ are not in the same chip.
