SDIO Wi-Fi speed + multiple Bluetooth devices in parallel - MDA II, XDA II, 2060 General

Hi,
since 3 days I own a XDA2.
1)
I wanted to buy a SDIO wlan card but then I heard that SDIO only makes ~ 40kByte/s
Is that true?
How can I get more speed?
2)
I wanted to use a BT Headset and BT GPS at the same time.
Somebody told me, that wouldn't be possible (single-channel ?)
What is the truth?
P.S.: Does anybody get greater upload (PC->PDA with usbserial+ipaq modules) speeds than 400kbit under Linux?
Download is fine (4mbit)
Under windows I get ~ 4mbit in both directions.

C'mon, there must be someone with an SDIO Wlan card and an XDA II.

1)
http://www.tekguru.co.uk/phpBB2/viewtopic.php?t=528
here is a benchmark of the xda2 with sd speed and all
not sure if it's the SDIO interface itself that limit the speed but i dont think it is i havent seen any tests of the transfer rate of the sdIO wifi cards on the xda2 but i dont think it would be limited to the read / write speed of sd mem cards
http://www.ppcw.net/?itemid=1650
here is a test
even if it were linited to the speed of the read and write of the SD cards
then it would still be much faster then GRPS hands down

2)
Bluetooth GPS and Bluetooth Headset work at the same time with no problems. I have a Jabra BT250 headset and a Leadtek LR9537 Bluetooth GPS and I use them both together frequently with no problems.

Thanks for your reply. This is brillant news for me.
I was already a bit disappointed having bought that pda because of the transfer speed and the bluetooth single channel rumors.
But it seems like all these rumors wheren't true.

Hiii
XDA II Bluetooth Data transfer speed is aprox. 700Kbit/s
A bluetooth headphone... use under 20kbit to communicate...
a bluetooth GPS use aprox. 4800 - 9600baud (10kb/s)
SDIO-slot is a powerfull IO port with Very hight speed data transfer support. I think up to several Mbyte/s
That test about SD storage card in a SDIO doesn't ment that speed limits are the maximum rates for the SDIO, but only for SD storage card's.

Allow me to quote my own post.
Today I bought said card and a first test gives ~ 480kbps
That's roughly 1/2 mbit which is quite sufficient in my eyes.
It's about the same I get via USB (with debug=1).

How can i use internet over bluetooth?

hi,
i want to build an bluetooth accesspoint at home, where i can connect with my mda-II to explorer the internet (wlan needs to much battery).
What kind of bluetooth usb device i need in my pc?
Can these work?
What kind of settings is needed on the mda?
(sry. i´m a bluetooth-newbie)
regards
AleX
The problem is that the XDA/MDA bluetooth stack doesn't support PAN (personal area networking). When the stack is sorted out then you only need a cheap class 2 bluetooth USB dongle and drivers to make this work.
Steve
I Have a Sandisk SD WiFi card, but as this kills the battery at home i use my laptop with built in WiFi and Bluetooth, I put my Laptop in the room where i am sitting, and then activesync over bluetooth, and surf the net thatway, the range is not bad, much better than the BT headset (jabraBT200) And of corse this way there is nothing sticking out the top ready to be snaped off, and the battery lasts much longer,
I will of keep the SD WiFi Card as there are also many times when i need it, But for home use as soon as they sort the PAN profile i will get a BT acess point
John
hi,
thanks for your answers!!!
@sweeney
Are you know if it possible to update the mda-II with the needed PAN support? If it is a microsoft-update or comes it from HTC or from anyone else?
@applecom
looks that we have the same configuration, i´m also use the sandisk wlan card but it takes to much battery power! But your idea with the activesync i like very well ... how you have to setup activesync to use bluetooth?
Are you useing the cheap "class 2 bluetooth USB dongle" sweeney spoke about or anything else?

No official support yet, but there is some sign of promise on this board that the WIDCOMM stack can be tweaked to work on the MDA/XDA and is known provide PAN, serial etc.

GPS: bluetooth or SDIO connection?

I saw GPS SDIO.
I'd like to buy but i dont know if really nice.
Someone has tried this GPS SDIO??
Which is more convenient receiver GPS (easy to work; battery life; etc.):
1) bluetooth
or
2) SDIO
Thanks.
ciao :lol:
You also lose ability for extra memory when using sdio gps, so no good for tomtom.
1. maps take alot of memory so Bluetooth is the best, you'll get the sd open for memory card.
2. You can strap the bluetooth receiver to a backpack strap so it keeps a constant lock
3. bluetooth can go on dash for good reception and xda in the back seat for the navigator

Ok thanks.
So what is the best receiver gps bluetooth for qtek2020?
TomTom bluetooth gps is very good.

Problem with QTEK 202 and GPS BT EMTAC

I have problems of loose of connection between my qtek 202 and my GPS BT EMTAC antenna.
I upgraded the rom of my PPC to 1.7202FRA
Any solution?
Have the same issue here!
But I don't loose the connection all the time. And it doesn't matter in my case whether I choose for TomTom wireless GPS, Emtac Wireless GPS or NMEA 0183v2 Bluetooth.
Haven't tried it yet with 3.03 or 3.07 of TT3 GPS driver.
Regards,
Mark
I got no problems with that
How do you know the connection is lost?
Could it be the know issue of asking a too big data throuput from the SD card (where obviously your maps & poi files are stored)?
If this is the case the isue occurs when eg. your speed is getting over a certain 'threshold'. This thresholp is determined bu the data-throuput capabilities of the SD-card (higher speed = more data/sec because of map movements).
Especially with the Himalaya the data-throughput of the SD-slot is limited. Some SD-Cards have more issues than others. Both my Kingston 256MB and my SanDisk 512MB make TTN3 freeze when the data-stream reaches the limit.
I know it is the data-throughput: Start TomTom GPS and to a testdrive. It will keep working, so nothing wrong with the BT connection.
Work-around:
1. limit the data-stream by unchecking all POI
OR
2. put your maps & poi in storage memory (limited by size!!)
There are some threads on this both here as on www.pocketgpsworld.co.uk
Many thanks for your answer.
I have only 2 poi checked.
Do you mean that i have to store the maps on a 256 mb storage card and not a 512 one
Sometimes the blue LED on my Holux starts flashing as it does when he doesn't find a PDA to connect to. TT continues but the data he thinks is receiving in incorrect.
What I do is : uncheck the box on the gps window (the one next to "Bluetooth gps" or "NMEA 0183v2 Bluetooth"), check it again and the connection is restored.
Gringo,
you can download BTHTOOLS1100.zip from :
http://www.bluetooth.jazztel.es/BTHTools1100.zip and install it
i've used i-mate rom172 + emtac bt gps for more than 7 months, and initially had the same problem, but then somewhere in this forum i found a thread mentioning about this and this solution (using bthtools) was adviced .
i'm now using xdaIIs and having no problem at all in connecting with the emtac bt gps.
hope it can help you

802.11g CF card (54Mbps)

Has anyone successfully used the new Linksys WCF54G 54 Mpbs card with an O2 XDA (or any XDA)? I ask as I need 54Mpbs to use Skype without the stutters I get from 11Mpbs using a Sandisk SDIO 802.11b (11Mpbs) card.
I only ask as when I first bought my XDAII I used a Sandisk CF card in the O2 backpack and cold never get it to work. The SDIO card worked straight away. I was never sure if it was crappy Sandisk software or hadware or both. :?:
Hi
It's not the wlan speed problem it's rather weak processor ~400mhz and software. Any of modern PocketPC's can't harness 802.11b speed not talking about 802.11g. So my advice is at first try to tweak wavedev using registry tweak if it doesn't help try to overclock processor.
here is reg tweak
HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev
change key Priority256 from it's default 110 to 80
in my device MDA Compact the default value was 256 and I changed it to 128 and all works smooth no stutter sound
yeah seing how slow xda's can read and write to sd memory compared to sdcard readers i would doubt that it could benefit much from a sd wifi 54Mb card
XDA 54Mbps wireless CF card

It's a CF card not a SDIO. Maybe quicker?

I cannot readily see the equivalent of REGEDIT .... any suggestions?
Thanks. :shock:
CF cards are by itself little faster than SD but you can find it out in PC card reader not PPC

There's no such setting as key Priority256 in the O2 XDAII. I'd say it is machine specific. I guess I'll just have to take a punt on the CF card and hope that works with Skype .... :wink:
Hey
take this program http://www.gb-soft.cz/xdaII/products.htm it's designed for XDA II and it adds some tweaking to GPRG connection but also changes the audio media streaming priority since it's for XDA II it must work!

Shamus: Thank you for this. It helped a little ... and clearly proximity to the Wireless AP plays a part. However, compared to my notebook which is running at between 36Mpbs and 54Mbps in the same location ... there are still clicks and the odd dropout.
The 54Mbps CF card is still looking to be the best option. I'll just make sure that the retailer/e-tailer will take it back if it doesn't work :wink:
stewarta other thing I needed to do with MDA Compact to achive smooth audio in skype was processor overclocking, without it I also had scratchy sound sometime. Try to overclock, it will help a lot. I'm using Pocket Hack Master, the best in this field in my opinion

Hi!
I have a O2 XDA II. If I'll to buy the Linksys WCF54G 54 Mpbs card I suppose I'll get a faster connection.
I also have the backpack for the O2 XDA II.
Now, the question is which overclocking software supports the backpack? AFAIK overclocking softwares does not support the backpack and if such software will to install you get problems reading files from the backpack's CF card
Any adavice? Thanks

Pocket Hacket Master is a great product ... particularly as you can define CPU etc slicing for various applications. However, it didn't help with audio quality at 11Mbps. :?

audio quality could be excellent at 11mbps, but as others said, the ppc itself is the bottleneck to audio quality, not the wireless speed. web-surfing over an 802.11b connection varies greatly in speed between a ppc and a real computer, and the audio is accordingly different quality as well

I can now report that the Linksys WCF54G 802.11g WiFi card works well in my O2XDAII. So well that there is no static or stuttering with FM radio stations or with Skype. I wanted to get a clean signal when using Skype, and that is what I now have. At last a good product from a great brand (Linksys is a brand of Cisco Systems). You don't need Hackmaster CPU speed-up or any other fiddling about as I tried with the Sandisk SDIO card ... which is now for sale on e-Bay!! :wink:
I just want to say that I have recived my Linksys WCF54G 54 last week and I am surprised... It's woks faster than my C-guys Sd card.

Yes ... it is so much faster than a SDIO card ... something to do with the architecture. I sold my SDIO card on e-Bay. :lol:

I am happy to report that the Linksys WCF54G 802.11g card coupled with my Himalaya O2 XDA II running Windows 2003 SE (see Radio details below) works well with Skype. Those at the other end also report a clear link. Turn XCPUScalar off though as my expereinces suggest a fixed CPU speed is best.

I have a c-guys SDIO card, but it doesn't work with my MDA COMPACT II. Does anybody know why? I downloaded a WM5 driver but no psoitive results...

I want a Qtek S200 but need to pair two BT devices. Any probs with BT 2.0?

I want to get a S200 and use it with a Spectec SDG-812 BT GPS receiver:
http://www.semsons.com/sp2blsdgpsre.html
And my Parrot 3000 that's installed in my Audi A4. I want to make sure both of these can run at the same time with no problems. I've read of posts where people have used one or the other but not a BT headset and a BT GPS receiver at the same time. I know BT 2.0 is supposed to be able to do this but I just haven't heard of many people using it that way on an everyday basis. Please post your experience.
If this is not a good set-up, I'll go with the Artemis P3300. That's actually my first choice but I like having a full SDIO slot where I can use big storage cards. Plus this phones been around long enough to have all issued identified.
