Q. r the 2 protocols of gps r SiRF & NMEA only? - MDA, XDA, 1010 Accessories

are these names protocols that gps uses & should any gps HW support either or both & therefore SW also supports both? please answer even briefly is possible

Can I use internal gps receiver with Tomtom mobile 6

Sorry about the noobie question, but I would like to know if it is possible to use the GPS receiver with the Tytn II with TOMTOM 6 software or is the only option to use an external gps reciever?
You do not need an external GPS recevier. The map applications are compatible with the built-in GPS receiver, just configure the appropriate COM port for GPS...

This is the most awsome thread ever. We should sticky it.

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.

Bluetooth

I know by default the stock rom doesn't support bluetooth, but is the hardware actually onboard and disabled, or not there at all?
I am wondering this as well...it would open up a lot of possibilities for the nook, such as a bluetooth keyboard...or even using it for Skype with a bluetooth headset...
BT reference in the B&N kernel sources
Hi,
I think it could be enable
In the kernel sources we can notice this :
gpio_direction_output(WL127X_BTEN_GPIO, 1);
Maybe it is the GPIO for BT enable
We just have to dig for the UART connection.
I think it's just a problem of BT licence.
Cheers Occip
Is there even a bluetooth chip / antenna in the NookColor? I did not see any on the tear down.
Integrated with the TI-WLAN

[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] External GPS+Bluetooth vs Internal GPS-Bluetooth

Hi
I'm interested in this question from primarily a battery life perspective. I did some searches, but couldn't find any info on this.
I have an external bluetooth GPS module I could use. If I were to use a Galaxy Ace with bluetooth enabled, but GPS off, would this be more power efficient than using the GPS of the Ace with bluetooth off?
(Assuming all other power factors to be the same).
I guess it boils down to: Which is more efficient on the Ace; using GPS only or bluetooth only? And is it actually significant?
If there are any other aspects that should be considered, please edumacate me!
Thanks

Personal experience and logic says Bluetooth consumes lesser battery juice than using GPS
Yes you are right wit an expternal GPS you will save battery, I use ana pplication called BlueGPS for pair the GPS and connect with Copilot
Thanks for the replies.
Now I've bought an Ace and had a chance to play a little bit, there's one thing that confuses me.
Once I connect the external GPS via bluetooth, and select it as the GPS source, I still have to enable the internal GPS for GPS to function.
(I can test that GPS is working via the external GPS by putting the bluetooth GPS unit on my window sill, and have my Ace inside where it can't get a GPS lock from inside via internal GPS).
So, doesn't this mean that the Ace is using battery for the internal GPS as well as bluetooth??

I guess what's actually happening is that when u "enable the internal GPS", you're basically enabling the phone to use the GPS source you initially selected in the location settings, i.e. the external one.
So all in all, when you have the bluetooth on without switching on GPS, bluetooth is idling, and when you enable GPS, it starts interacting with the bluetooth GPS.

hi
I am using external bluetooth GPS too.
I did flash my phone two days ago and find out that I don't need another app to use external GPS.
My phone is flashed with CM10-nightly.
Problem is that after each time when I want to used external GPS I need to unpari and then pair that bluetooth device.
example:
a) switch on bluetooth, and pair external GPS device
b) choose that new device in GPS source
c) switch on GPS
perfekt I can use maps ...
after while I switch off GPS and bluetooth and device
then
d) switch on bluetooth, device is already paired
e) switch GPS, external source is already choose
BUT phone is not getting any data from external GPS device
f) I have to go to bluetooth devices and unpair and then pair external GPS device
I think it is a bug, what do you think?
