GSM/GPRS and Roam

Hi,
I've been having problems getting some cellular info for my program. In both cases I open a tapi line to the "Cellular Line" device...
Problem 1:
I am trying to use lineGetCurrentSystemType() in extapi to get information about the current connection type. In other words I want to know if the phone currently has GPRS or GSM capability. I can successfully open the line, but everytime I call lineGetCurrentSystemType() I get LINEERR_OPERATIONFAILED. Can anyone help with this, or offer a better solution?
Problem 2:
I want to know if the phone is roaming, or on its home network. I've been using lineGetLineDevStatus() from TAPI, but dwRoamMode is always LINEROAMMODE_UNAVAIL. Can anyone tell me how to get the roaming status?
Thanx,
Blair.
PS. For those that have been asking, lineGetLineDevStatus() also has a dwSignalLevel property that I've been using to get the signal strength / signal level of the "Cellular Line" device.

Just a quick question
Hope you don't mind me asking but....
Reading your P.S. I was wondering how difficult it would be to use the Get Signal Strength Call to provide an alert when Mobile Signal is lost, just a load beep/beeps would do. I rely entirely on my mobile for work. I have to be contactable at all times. On my old Motorola V66 I could set an alert tone to inform me when I have no signal, but there does not seem to be any way to do this with the XDAII!
Any info (or a working app) would be greatly appreciated!!
Thanks

HSDPA/3G automatic switching

Hello,
I have just upgraded to the official GPS ROM and I am on the Swedish 3 operator. I have noticed since the upgrade that the network connection is switching from 3G to HSDPA when there is a demand of bandwidth or simply when there is data in either direction.
I can see that the purpose of this was to make it possible and more reliable to place and receive calls during data sessions. I have figured out though, that with the old ROM, there was no such switching (but there was no distinction with the icon, so you really had no idea) and the connection speed was always constantly 1Mbits/s when using Internet Sharing for example. Now with the HSDPA/3G switching/throttling, the connection often drops down to 3G speeds and Skype-calls are lacking quality from this a bit when using Skype in the car which i do quite regularly nowadays using my Jabra JX-10 headset.
I also realize that there is still a problem with outgoing and incoming calls during these automaticly switched-on HSDPA-sessions. That is probably why HTC has decided to keep the HSDPA sessions as short as possible, that's fine, but what boggles me is the algorithm used for the switching. It seems to always kick in HSDPA in the beginning of a new data session, and after a short time of inactivity (while pondering what favourite page to open this time) the connection drops down to 3G and it won't kick back to HSDPA even when you start browsing again, until a certain period of "non-HSDPA-ratio" has been reached and the phone thinks it would be OK to kick in the highspeed again for a little while.
I also noticed that using Skype would keep HSDPA alive once you place a call from a fresh started data session and keep talking ;-)
This is not a particular problem to me, I was just wondering of anyone else here has noticed and had an idea of what the programmers had in mind?
BTW: I am running TomTom 6.010 and Franson GpsGate on the machine now and it works absolutely like a dream. I used to have a Blue-I Bluetooth GPS in the car (Trimble based chipset, only 8 channels but quite OK piece of hardware) but this is far superior when it comes to HOLDING a persistent fix also when moving indoors. The TTFF is quite fast as long as you are outdoors, most of the time i have a fix before i leave the parking space. I noticed there being a dynamic number of satellites of the receiver, sometimes i see 7 out of 8 satellites, and then sometimes i see 10 out of 12! Anyone noticed?
Thanks in advance! Cheers...

It’s not your phone that decide to change from HSDPA mode to normal R99 (384kbits) mode and vice versa. Everything are always controlled by the network. The behaviors that you describe are normal. Besides the HSDPA is quit new for the operators and new parameters needs to be tuned for best performance for every users.
BTW, the degradation that you notice. You are not alone that use HSDPA.... Its finally the big success for 3G

I use Phone Alarm profiles and BandSwitch to control my connection based on business hours. I get a poor singal unless on 3G where my office is located. I force it to GPRS otherwise to save battery.

I have similar problems, cannot receive or start calls when HSDPA connected. Shouldn't that be possible anyway, calling and transferring data at the same time? Or is this a network provider problem?

I too am on the Swedish operator 3. I have an unlocked, non-operator distributed HTC TyTN that I had updated the radio to 1.40xxx and the ROM to Black Dymond 3.5 and was having the exact same problem. I could reproduce the incoming call not getting through error every single time I got the phone to go into HSDPA mode.
After some initial searching I read somewhere it was network dependent (Nokia switches vs Ericsson) and the only way to solve it was to disable the HSDPA using e.g. HTweakC, which I did and it solved the problem, but then of course I couldn't take advantage of the high-speed data access, which was the major reason I got this phone.
I recently noticed that 3 released a new extended ROM with instructions to update the ROM to the latest (as is available on the ftp here) then install their ExtROM. I went to the trouble to try and breakdown what was in this extended ROM, but being a newbie to pocketpc it was all hyroglyphics to me, so I went ahead and installed it over my old HTC ext ROM (which I saved for later use just in case).
When I get around to it I may mount this extended ROM here (I have it, but don't have too much time to put it up right now, so someone may beat me to it).
Anyway, Black Dymond 3.5 didn't install the Extended ROM after a hard reset (assuming that was the intention), so I did it myself afterwards. One initial bug that showed up quickly was the Comm Manager not wanting to start saying it would only manage a max of 7 items (whatever that means). So I installed Schaps latest Comm Manager and it worked fine.
Well, guess what, now there's a daemond that starts on boot and the phone app is different (another bug is that the text on the phone app buttons remain in the 3 theme although I changed back to black, but that's minor), but now I cannot replicate the no incoming calls during HSDPA error.
Apparently they've added something that makes the phone connect properly to their 3G/HSDPA network for call handling. Now I've got full HSDPA speed and no problem on incoming calls (plus still have Black Dymond's great VOIP/SIP WM6 solution).

Ok, as a noob I of course missed the fact that the daemon starting at boot is Voice Commander. Still the actual phone app/dll is somehow different with this ExtROM and it's solved my problems.

No Service - No Network !!! HELP !!!

No Service - No Network !!! HELP !!!
--------------------------------------------------------------------------------
Hi,
Novice at all of this so be patient !!!
Deleted a few files from the phone (usual monthly clearout !!) and all of a sudden it cannot find a network .... I have tried a couple of SIMS in it but it will not recognise any signal or signal strength - just has an exclamation mark next to the signal bar.
Any suggestions/help gratefully recieved as needed for work !! Who aren't very happy !!
Cheers
Rob.

First question, (I hope you don't get offended ); check to see if the flight mode is on, if it is, then turn it off.
Second, question, what files did you delete?
Third, if all else fails, backup your contacts and mail (I would suggest not doing a full system backup, it will just revert the phone back to the state it was in); then do a hard reset.

No Network !!! HELP !!!
Tried - NOTHING !!!
Flight Mode definitely OFF ;-)
Hard reset - came back the same.
Didn't think I deleted anything apart from pictures etc.
Any other suggestions ?

No Network !!! HELP !!!
Just Noticed Something Else That The Phone Does Not Do ..... I Cannot Get Into My Contact, Calendar And Even When I Press The 'green Phone' Symbol Nothing Happens - I Cannot Even Dial A Number !!!
However, Resco Still Works, Games, Settings Etc. !?!?!?

I´m having a similar problem.
Sometimes, when my signal goes down due to range problems the indicator shows an "!" or na "X" even if i´m back to a place where the signal strength is good.
I know the strength is ok cause I have another cell phone from the same opperator.
To solve this problem I have to reboot several times my Wizard. During this process it receives and looses the signal.
I don´t know why this happens. Any sugestions?
thanks

Ihave the same problem on polaris.any ideas?

If the device will sync via ActiveSync, try loading your service provider's default ROM to the phone. If you're willing to do a hard reset, this isn't much of a reach, and it should install the missing files. It's about a 90% chance that you accidentally deleted a config file or library that you needed.
If it won't sync either, that's a much tougher problem. Search these boards, you may find alternatives.
Next time, just download and install ClearTemp for expunging useless files, and don't delete anything you can't identify. (Google is your friend, in this regard...)

neither hard reset or cleartemp can fix my problem.i think i will throw my mob on the wal.its really a shame to pay almost 800 usd for a device that cannot do the most basic job.to connect to a gsm network.what a shame.........

Update your signature with the rom number and maker; your device information; and your carrier.
there is a cab file "Network Wizard" if that does not work, flash a new rom.
People can not help you if you are not listing information about your device and rom.
YOU PAID $800 for a wizard?!!!

HTC 3600 Questions (GPS, 3g Browsing etc !)

Hi all,
Firstly, apologies for being a bit of a newb here, but this is my first ever PDA type phone, and im getting myself confused, and for no real reason it seems !
I've done a bit of searching around, and from what I can work out I am going to make a few assumptions
1 - I should be able to, without using my WLAN connection, browse the internet on my HTC3600 through internet explorer, using my Vodafone 3g or GPRS connection.
2 - there is a way to enable some random wizardry chip inside the phone to activate GPS, and if I was to install TomTom Satnav software, this would work with no extra dongles etc.
Now. if my assumptions are correct (and one should never assume anything) I would be greatly appreciated if someone could in easy to follow newbie freindly (as in, click on start, programs,) instructions as to how I would ...
1 - do what is required to get GPS working
2 - do what is required to get the 3g web browsing working.
Im sure this would be a useful sticky if you cna help me do this, but having a search round on the forum I havn't seen these instructions spelt out. Aware that whatever you tell me I do at my own risk etc, but would really appreciate some help here
cheers all

Usually I would say search and stop being a noob but I'll be nice today.
1 - I should be able to, without using my WLAN connection, browse the internet on my HTC3600 through internet explorer, using my Vodafone 3g or GPRS connection.
Correct, however you'll have to setup your internet settings for Vodafone, you can usually find these settings on vodafone's support website or by calling customer service.
2 - there is a way to enable some random wizardry chip inside the phone to activate GPS, and if I was to install TomTom Satnav software, this would work with no extra dongles etc.
If you have an older ROM loaded on your P3600 then yes you'll have to upgrade it to enable the GPS. You can check your ROM by going to start->settings->system->device information if it's 1.15, you'll need to upgrade it to get GPS, however if it says 1.23, your GPS should already be enabled. You may also want to look into upgrading your P3600 to WM6.
Here are some useful links

BTW, don't get too attached to this phone, the screen will probably stop responding in about a month and you'll have to send it in to get serviced.
Good luck.

Don't do anything apart from going to Start/Settings/System/Device Information and checking what is listed for Radio ROM. If it ends in **.**.11 it is GPS enabled. If not, as vanydotk says, you will need to update the Radio ROM.
Any GPS aware application (TomTom etc, etc) will automatically initiate the GPS receiver as needed, as long as the applications settings point to the correct GPS port (COM9) You don't need any additional hardware.

Make sure you have a 3G SIM card, and 3G is enabled on your account (it isn't always).
Use This Guide to manually configure the Vodafone settings (HTC did have an automatic file to do this, but it's been pulled from their site). Note there are different settings for contract and PAYG accounts.
Be very aware that mobile browsing can be very expensive. Before you do anything, make sure you buy a data bundle, or it may cost you up to £3 per MB of data.

Also a newbie and had spent some time reading the forum looking for answers... Can any experts clarify and/or confirm my question below? I know it s a very basic question for many here, but I would really appreciate it if someone can help me to get this working.
Do I have to have Mapping software installed on my Trinity in order for the GPS to work?
I go into the Camera mode by pressing the "shutter" button. Tap on the camera icon (upper left in landscape view) to enable GPS. However, nothing happens. Looks like it just keeps trying to start GPS.
The screen message reads: "Initializing GPS..."
What do I need to do to get the GPS working?
According to a previous post. My device came with the GPS enabled based on the ROM versions on my Trinity.
Some info:
I purchased my D810 in Hong Kong but I am using it now in Taipei.
The ROM info are as follows:
-ROM version: 1.23.707.6
-ROM date: 02/08/07
-Radio version: 1.35.00.11
-Protocol version: 32.68.7020.10H
OS 5.1.461 (Build 15671.3.3.0) Windows Mobile 5.0 with Messaging and Security Feature Pack. English version.
I am currently on a pre-paid phone service (FarEast Tone) so I do not have access to 3.5G, etc.
Thanks in advance!!!

[Q] An app to gather network health statistics?

Hi all!
I'm an Android user. I use it heavily for web-based uses - browsing, streaming music and various network-enabled apps. And I'm a little disappointed. The problem appears to be a network issue, but many, if not most, of the time, I can't get a reliable data connection on my phone. GSM is totally fine - never had a dropped call or lack of reception. Just data. Even when I am in a area of strong coverage (full bars; 3G/HSPDA icon showing) I frequently am unable to do simple web access - can't open Google, or an app is unable to do light data connection (e.g. Facebook app grabbing a profile). Sometimes it works fine and when it does, it works bloody fast. But it's that unreliability that is frustrating.
Now, I'd go to my network and ***** about it but they - quite understandably - would be unable to do much about it without a more technical description of the problem. They'd just find some way to blame it on something else, as they do. What I'm looking to do is characterise the problem by gathering some stats on connection reliability. If such data could be collected, I would be able to back up a case that there's something foobarred with the network (or persuade myself that there isn't).
Question is: does such an app exist? I'm not looking for one of the many speedcheck apps; I'm looking for something I can run for a couple of days during which time it tries to make many mobile data connections. It would record success/fail, reported network strength/type, perhaps latency, connection speed and location as well. It would do so once every, say, 5 minutes, to build up a profile of how the reliably I can get my connections.
Anyone know of such an app? If not, I might write one; do you thing such data would be useful?

Sheepish bump...
