Why is the GPRS baud rate fixed to 19200: even if I select another one(Start>Setting>Connextions>Modify>selectconnection name> baud rate>next>finish), it always comes back to 19200. I did not have this problem on iPAQ.
Does this 19200 bps max default setting impact or limit actual bandwith ?
this setting has no impact on the actual GPRS speed ... you can test your GPRS connection by browsing this page from your XDA
www.texan.net/speed.htm ... you must do Refresh more than once to get the actual result.

I've had no problems getting the GPRS to work on O2. The connection speed stubbornly refuses to move from 19200 and the connection doesn't feel as quick as it should be. Whenever I change it and go back to check, it has reverted to 19200 baud.
?
The Serial port should be greyed out when selecting the Cellular Line as it is not used, but hey, Microsoft aren't perfect.
It has no effect whatsoever on the data throughput of the device.
This is a known issue on the Pocket PC devices. AFAIK this is a gui issue. If you select anything above 19200 it will stick, but when you go back and view your settings it reverts back.
You'll still connect at the higher speeds.
Whats the diff between csd and gprs. Right now I created a new connection by doing start; settings; connections; connections; modify (internet settings). Under "My connection" I have it set for "cellular line (GPRS)". Under baud rate it is 19200 (why so slow?). Clicking next I have "wap.voicestream.com". This works but is really slow. Is this the correct way to use GPRS or is this CSD? If not, what is CSD? Is it better. Sorry for so many questions but I really dont know much about this. I have t-mobile in the US (southern california).
CSD (Circuit-Switched Data)
CSD is similar to your PC dialing up to a ISP / corperate modem pool for a data connection. For XDA or a cell phone in general, it consumes your air time. (If you make the CSD call during nights & weekends with T-Mobile, air time is free.) You get a 7Kbps avg narrow pipe - pulling an Internet page is very slow, but you can turn off the graphics on XDA to speed it up. GPRS is designed for data, giving you 40Kbps avg pipe, comparable to your PC dial-up speed but you have to pay T-Mobile $20/mo for unlimited data service. See thread

for setup. Hope this helps.
Can anyone help me in setting up GPRS on SFR for the XDA2 - I have searched and tried everything but still no good
I have the settings, in fact I have loads of settings and not enough boxes to put them in!
Help!
Still trying to do the above
Settings > Connections > MyISP > Add new connection
Select Cellular GPRS
I can add the APN - no problem
I get no option for Baud Rate
No where to put *99# as the phone number
No where to put Z+CDGCONT=1,"IP","websfr"
Do I need to set up another connection under 'Hayes' to put this other stuff?
Help! Please
I get no option for Baud Rate

Click to expand...
Click to collapse
i'm pretty sure those are not needed at least i've never sat any of those things
would think it's settings required if you are connecting to another mobile or something
Thanks Rudegar,
So all I need is the APN of 'websfr' and DNS of 172.20.2.10 and it should work as a Cellular (GPRS) connection?
well not sure about dns i think most networks assign the dns and ip addresss for you of cause yours may be different
and unless your phonecompany require you to use login and password
and if they open'd grps in their end
then you should be all set
If there is no GPRS available or much too expensive (roaming) i prefer to use HSCSD. I have configured my hw6515 to access my ISP via CSD. I was using a HP Jornada 568 with a Nokia 6310i before, where I communicated to to the Nokia phone via bluetooth. The nokia was opening a HSCSD connection to my ISP. Now I would like to do the same with my hw6515. It seems to me that the hw6515 only connects with Normal Single Slot GSM Circuit Switched Data (CSD) @ 9600 Kbps. I am looking for a way to configure High Speed Circuit Switched Data (HSCSD) Multi-Slot GSM data calls of maximum uplink/downlink speeds of 43.2Kbps/14.4Kbps or 28.8Kbps/28.8Kbps.
On the Nokia 6310, I modified the dial string to force the modem to use HSCSD channel bundling in the following way:
9.6kb: AT+CBST=0,0,1;+CHSN=1,0,0,0<cr>
14.4kb: AT+CBST=0,0,1;+CHSN=2,0,0,0<cr>
19.2kb: AT+CBST=0,0,1;+CHSN=3,0,0,0<cr>
28.8kb: AT+CBST=0,0,1;+CHSN=4,0,0,0<cr>
43.2kb: AT+CBST=0,0,1;+CHSN=6,0,0,0<cr>
or
Automatic Negotiation
AT+CBST=81,0,1
Does anybody know how to configure the iPAQ hw6515 to do HSCSD?
:roll:
I purchased the Cingular 8125, which has edge. To acchieve the maximum speed with the edge connection you have to use the cingular proxy servers.
I WANT to use the proxy servers because my testing has given me an average of 300kbps down when I use the proxy vs. 96kbps without.
When I enable the proxy servers, I get a Support code: 0x80830003 from activesync. Microsoft's article (http://support.microsoft.com/?kbid=830563 says its a problem with ISA, I don't use ISA, I think is just a problem with going through a proxy server....
Currently I don't have the server set up to use HTTPS it connects over HTTP.
Is this the problem? If I change to HTTPS, will it work? I actually though of the HTTPS while I was typing this... I will give it a shot, and let you all know how it goes.
I'm using Cingular's proxy and am having no problems with OTA-Activesync. Additionally, Push is working for me as well.
This is with the phone's default config. Now, what doesn't work for me is PC passthrough and WiFi connectivity, but I've got other threads out there for those issues.
how are you testing the speed?
Keep in mind you are not getting an exact connect speed what you are getting is an accelerated connection thru the proxy this can be seen the most if you stream media you will see the stream speed is considerably slower than the test speed.
