building your own gps antenna - MDA, XDA, 1010 General

how do i build a gps antenna for mij xda and where do i get my conectors

hhhmmm how are you planning to connect the antenna ?
i mean there buttom connector dont have any pins for antennas
suppose you could put a stylus shaped stick into the xda1 and
have that connected to a antenna ?

I think he means
He is going to build a GPS mouse, and then want a 22pin connector to connect the mouse with the XDA (or mayby i got it completely wrong)

The easiest way to is to use an existing usb to xda sync.charge cable, introduce the 3 wires from gps into the xda connecter after removing shoud, you then have a cable that will power the xda as well as carrying the data lines to gps.

yes he's right . build your own gps mouse and connect it to the xda.and to make it compleet ad a cigaret charcher to the kabels as wel
thanks we are getting there

XDA II Antenna Connector

Does anyone know of a source for a connector for this? I already have a GMS antenna with the standard FME connector. I am looking for an XDA II to FME pigtail??
I dont think the antenna connecter is for direct connection to an antenna, it does look very similar to many car kits though, the phone sits in the cradle and the connecter mates with its opposite number on the cradle, maybe you could cannibalise a car kit and solder the end to a cable.
Very strange, most other phones with antenna socket have a corresponding connector on a pigtail cable. Will have to look into trashing a car kit.
Maybe it is available, but I just havent seen it.

Kensington Power Adapter

I found a very nice & Slim universal charger on Kensington's site for Notebook, PSP, Ipod (yes I have all this stuff in my backpack...), but a tip for hermes seems to be missing.
Does anybody now a similr device with Hermes tip too?

Basically anything with a mini-USB plug will work.
That's not been my experience. If it connects something to the data pins it will work, if not, it won't charge correctly.
I used my old Motorola V3 wall charger to charge mine for a while, worked fine - thats a standard mini-USB connection. Also used a Motorola V3 car charger, and I've just bought a Brodit car cradle for my device which has a fixed mini-USB which works fine?

Interesting. We've found that unless the charger has pins 4 and 5 bridged ('unused pin' to 'ground') on the mini usb end then the hermes will act strangely. It will start charging the first time you insert but then it might stop and then it won't charge again until you reset it.
The pin doesnt need to be bridged when theres a data source like a pc on the other the end.
Could you check to see if your chargers have those pins bridged or not?

I have not been doing any kind of research about bridging those pins because I just read about it first time, but my experience about charging problems are very similar to yours. My TyTN won't charge normally via USB-hub or car-adaptor, and after failing the charging process, it won't start charging again. Resetting helps after this, but I think that also waiting resets the situation. But that I'm not so sure about.
When I connect it directly to PC, it works just fine.
If bridging those pins helps, my car charging problems are wiped out

Yes, they are tiny at the other end, but bigger at the other
And if that causes still problems, cutting the wire is not so big deal either, then you can easily connect wires together

Except that pin 4 doesn't have a wire connected to it (only 1,2,3,5) because the other end only has 4 pins

Damn .. then it's not so easy.
But I guess it's still possible, without totally breaking the plug. I hope ...
Interesting. That is exactly the issues I see using a 12V/USB adapter and cable in my car. Well hopefully in 2-3 months when my free vehicle charger comes from Cingular it will have the pins bridged and work properly!!!!
I wonder if the bridged pins and data cause the bluetooth to turn off after a period of time. I see that happen on my phone often when its connected and charging. But disconnected from the 12V/USB charger the BT stays on.
Thanks for testing and posting.
I had this exact problem with my m5000 to, i use a ipod battery extender as a backup for my m3100 as i regularaly find the need for extra power.
Quick work around for this problem is to power down completely by holding the power button. Then plug it in while turned off, wait for charging light to go orange then switch back on, will continue charging then until plug is removed.

V3
So, I don't understand: in the end, does it work or not with an adapter for V3?
If yes I could by that...
TX
If it helps any, I use an iGo universal power adaptor (available from Radio Shack and Expansys) which uses the iTips style device-specific tips. This is very similar to the Kensington system, although I believe the two are now incompatible.
Tip A53 (which is also designed for AudioVox phones) works well for me with my T-Mobile MDA Vario II.

car charger cable + radio antenna

Hi everybody!
I would like to use my TOPAZ with GPS and TMC in my car, but without charging, the batterylifetime will be very short.
Does anyone know if its possible to get an charging cable witch integrated antenna for cars, or something similar I can modify to do this job.
Maybe I can combine a normal Headset with a charging cable.
thx
I am using this one. Very good to fix and give a good position to view the GPS maps. Besides, recharges battery and has a speaker/mic system so that you don't need to enable the speaker on the phone to receive or make calls.

Haven't found any one with a antenna for either GPS or Cell radio, yet. It seems TD2 won't support external antennas.
Regards,
Roberto.
yeah, i'm looking for such a cable too. but havent found any yet.
cant be so hard to integrate some wire for radio in a charging cable.
i bet a lot of people would like to have it.
update: now i found two accessories which might help.
http://www.amazon.com/HTC-Audio-Cha...17?ie=UTF8&s=wireless&qid=1250514224&sr=1-217
http://www.amazon.de/Diamond-Y-Adap...r_1_28?ie=UTF8&s=ce-de&qid=1250514463&sr=1-28
i think i will check out the first one and hope it works for the antenna too.
Home made cable
It's very simple to make the cable yourself. I have done it and it works perfectly...
What I did is the following:
1) I took the headset from my old Tytn II (or use the new one if you can lose it), and cut it just before the volume control (seen from the phone).
2) I cut open the usb connector, took off all plastic insulation (is some work) and disconnected all cables except for attachment number 7 (see figure), which is the antenna cable (this is the strand of small copper cables without further insulation around it).
3) I took a car charger and cut off the usb connector and soldered the two wires to attachment numbers 1 (red wire) and 5 (black wire).
Be very careful to solder very well, because you don't want any shortcuts...
Voila it's working.
Even better is the following (which I'm going to do now, now I know it's working):
1) Buy the following connector:
http://www.coolcomponents.co.uk/catalog/product_info.php?cPath=27&products_id=266
2) Solder a simple cable of about 0.7 mm^2 and 75 cm long to port 7 and solder the car charger to ports 1 and 5.
That's it...
Combine this with the following software:
http://forum.xda-developers.com/showthread.php?t=512630
And you will have TMC available in IGO or other navigation software.
Hope to hear if it works (for me it does). I have TMC now and charging when using my IGO, and besides I can use my bluetooth carkit, because it doesn't think there is a headset connected to the usb!!!
@amraam12: Wich rom and radio rom version you are using? I tried the same, but no luck: when putting +5v on the charing line, the radio gives no signal. (http://forum.xda-developers.com/showthread.php?t=535358&page=3)
rom
rom: 1.39.114.2 (47382) nld
radio: 3.43.25.19
Antenna only
amraam, in case I just want a better reception provided by an external antenna and don't need to recharge while connected, if I solder an antenna connector to pin 7 (and 5 = GND) in a extUSB connector I'll be able to have much better reception, right?
How about using an antenna like this (http://www.wpsantennas.com/301103-wilson-cellular-magnetic-mount-cell-antenna.aspx) for that? Do you think that may work to improve reception on low signal places?
From your tests, how better is using the external antenna?
Thanks.

That is a TMC (Traffic Message Channel) antenna. It is used to receive info about traffic from a specific FM channel so that GPS can calculate better routes. I don't know exactly if it is connected to pin 7, but probably is. To use that service, it should be available in the place you are driving. I am just guessing, but Pin 7 seems to be only a connection to an antenna for FM frequencies (around +80 ~ 108MHz).
I haven't found anything stating it can also be used to received external GPS or Cell Phone radio external antenna signals. These are all very different frequencies, btw.
Regards.

Is it possible to receive fm stations on td2 while it is connected to this charger?
If so, maybe also tmc data could be received by it without pluging in the headphones.

Prime, dock, and GPS Dongle all together?

Hello everyone,
I understand that the GPS Dongle for the Prime occupies the ASUS 40-pin, which means it won't allow the dock to be used. I'm just wondering whether it is possible in the future to have a cable with compatible ends at both side? Of course it should be male/female to be used with the dock's left hand side female.
This way, theoretically, I would be a able to use my Prime, dock and the GPS Dongle all together while travelling. But I'm not sure that it's possible, even if such cable exists... sometime in the future.
Probably some of you out there have any opinions regarding this matter.
No cable for this currently exists.
However one could be made, if the connector is a straight pass through then it would work. If the connector however only utilizes certain pins then it would either need to be modified or replaced.
Either way it will take some experimentation.
The easy way for now is to remove the device form the plastic housing and plug it into the dock to see if it works.

Yes, I understand that it cannot be done at this moment. But theoretically it might work, right? Or is there something in the dock prevents the GPS to get connected to the Prime? Such thing like, power line (charging) is more priority and is using the same pins?

Theoretically time travel is possible, anyhing is possible theoretically,
But to answer your question, no there are no pins which share data/power.
The only worry is that the dock female connector may only be power and ground, no data, I know this to not be true as I rooted while in the dock, so all pins pass through from what I can tell.
It looks like for ease of manufacture all o the connectors are the same on the tablet, the dock and the dock plug.
A wire or new housing should be easy enough to fab up.
I will test this tonight.

This means we will need to open the dock and connect the lines that are not connected if we wish for this to work.
Though it seems to me that this may be a specific doc pin being recognized...

Thanks a lot...
a little bit pity 'though, since I have a plan to use them all together on the road.
im currently in the process of tracking down which pins are used in the dongle, unfortunately i only have one dock and its too expensive for me to start ripping it apart however hopefully with the information im gathering and information others are gathering we can get a pinout for the dongle as well as the prime and dock to better understand how everything works
I am having difficulty with Asus support. Would like to buy a GPS Dongle if a member does not need it. Thank you.

Internal GPS / WIFI Connection socket type?

I've torn apart my Prime in hopes of fixing the lack of GPS and horrible wifi. My issue is absolutely and unfortunately a hardware one and I am looking for ways to resolve it. Upon tearing it apart, I noticed that there were two mini ufl type connectors that I traced back to the horrible pogo pins. Im thinking of adding a separate internal antennae to the connectors to see if it helps my issues any ( attached pic is of the GPS/swan/Alan antennae I will order ). The thing is, I cant find this particular type of connector anywhere online to order the proper plug for the socket. Ive already found a thin antennae that I want to use ( and I may even mod it to the exterior of the case ). Can anyone with working radio knowledge take a look at the attached pic and let me know what type of socket this is ? Its much like a regular internal wifi socket but just a hair smaller. Thanks!

I took a couple more photos with the plastic covering removed. It looks like it should be relatively easy to add another antennae if I can find the proper cable to solder to it. You can easily trace the bulk of the IC for the antennae wires
I removed the left pogo in hopes to solder the connection to the pad but couldnt get it to stick.
Sent from my Transformer Prime TF201 using xda app-developers app
Ok, another quick update. The Pogo pins are the antennas center pin. The ground is actually a body ground to the back casing via that little copper pad making contact to the silver foam pad stuck on the case which is shown below in the case just above the pogo pins. I greatly increased my wifi signal by soldering a small lead to the copper pad on the antenna and grounding it to a case screw next to the camera. I also cleaned the silver plate on the antenna to ensure the pogo pin makes contact. I still have had no luck getting GPS up and running.
Side Note,
There is a bridge that looks like maybe a HFL socket on either end on the left side of the mainboard near the single pogo pin. Im going to order a short bridge because when i carefully removed it, the end fell right off leading me to believe the end wasnt crimped on properly. So far 2 design flaws Asus........Great job! The other odd little connector seems to be a testing point. Apparently it breaks the lead to the antenna when the tester probes into it. Im wondering if the internal mechanism in the testing socket is broken and is causing the lack of connectivity to the regular antenna for the gps? im going to solder the ground wire and a main wire to the GPS antenna when I get a chance , fixing the ground to the mainboards grounding plate, and carefully test the other side of the resistor leading to the test socket. This should let me know for sure if the sockets center pin is breaking contact for the pogo pin.

Thanks for the kind words guys. It might be a few days before I can take more time to work on this little project. If this pans out, Im also thinking of adding a 3.5mm jack to the top right side so we can plug in a straight external antenna ( Just above the headphones jack ). Im a mandatory city employee and we are still dealing with this hurricane here on the east coast, so my time is short for the time being ( damn 12 hr shifts lol ).
Here is the antenna in thinking about modding the case to fit :

Here is the internal part for it. Id just solder the leads to where the gps pins have an active connection. It looks like there is enough space in the case in the top right corner to fit the internal component. Id likely just drill a clean hole and hot glue it to the case to keep it from moving around. From there its a simple solder to the leads to make the jack active for an external GPS

This kind of makes the gps completely null. Im trying to get it actually working LOL.
I should have time to flash / tear down tomorrow to determine if the connection to the testing socket is causing the break to my antenna. Apparently when the probe pushes into the sockets internal pin, it intentionally causes the external antenna to detatch and im thinking when the probe was removed, something got stuck causing the test socket to stay active. This is all according to the very little bit of information ive seen available on the test socket. My GPS does not function at all what-so-ever even if I remove the metal back case and run a wire to the pads on the antenna ..... My issue is purely a hardware one. There is a physical disconnect somewhere in the antenna circuit which is why im trying to build a permanent fix. If I can make some kind of contact to the gps module, ill likely solder / drill / mod the case to fit a nice looking external antenna. Im even thinking of something similar to how the IBM laptops have their modules set up on the exterior.

Even the little bit of whining I did about my linksys rounter was helped by turning off access to 802.11a at my router.

Update :
I removed all of the pogo pins on the upper pcb and attached a lead wire to the GPS and WIFI antennas. I was actually able to get 2 or 3 satellites leaving the antenna outside of the case. It may well have been a bad connection on the pogo pin causing my hardware issue. Ive gone ahead and ordered the 4 pole 3.5mm jack and nokia n97 3.5mm gps antenna. Something tells me ill have me a nice mod on my hands I just hope the 3.5mm barrel jack isnt too large to fit where im hoping to put it.
The waiting game from China begins lol
If that doesnt work, Im planning on carefully drilling a hole and permanently affixing a thin external gps to the back of the tablet similar to this one :

If that does work, Ill attach a laptop wifi antenna inside of the GPS antenna case and solder it the upper pcb. Since they work on two different frequencies, I dont think they should interfere with each others operations.
