Cannot oper/register serial port for Bluetooth

I'm developing, for XDAII and in eVC4/Win32, an application that opens a serial port for incoming Bluetooth. The Bluetooth Manager sets COM4 as active port number, but my call:
CreateFile(TEXT("COM4:"),GENERIC_READ | GENERIC_WRITE,0,NULL,OPEN_EXISTING,0,NULL);
fails with error message "The specified network resource or device is no longer available".
When I then try to call:
RegisterDevice(TEXT("COM"),4,TEXT("ASIC5_BTUR.Dll"),0))
also this call fails.
What am I doing wrong ? When I look in the Register [HKEY_LOCAL_MACHINE\Drivers\Active] I find no COM4 active so there is no obvious reason why this call should not work. Have the BTHTools1100 patch installed !

Hello, I am experiencing similiar problems. Have you resolved yours ? If yes, could you show me how you open your ports etc.?

read this :

I am not sure how your link to COM1 prolems regaqrding signals sould help me. My problems are with opening Bluetooth SPP ports, those that show up as the Inbound and Outbound COM ports.Though I would think that both are active, üsing CreateFile() I can open only the Incoming one (COM4) while I receive an INVALID_HANDLE_VALUE for the other one (COM5).

I just saw some info on com ports being inactive as well as a test program so I thought I'd mention it. Didn't mean to provide a solution, sorry

I tried to get the Bluetooth working and also had trouble. I think the inbound and outbound comm ports is to do with if you are using your SPP device as a client or server. It is not as a lot of people think that TX and RX data are on different Comm ports.
I cound not get Bluetooth working at all using my original XDAII rom of 1.60. I downloaded Pocket Bluetooth Tools http://www.bluetooth.jazztel.es/ and then it worked easy on Comm7.
I recently upgraded my XDAII Rom to 1.72 and I tried the Bluetooth support again. This time the XDAII even said I am connecting to a serial SPP device and automatically allocated the Comm port. But I must say my program could still not transfer data correctly using it. It all got stuck in some initilisation sequence. Now that may of been my software so I don't want to blame the XDAII.
All I know is I installed Pocket Bluetooth tools again onto my 1.72 XDAII and all worked fine again on Comm7.
A friend of mine has a new XDAIIs and the inbuilt bluetooth support on that worked 100% first time, no need for the Pocket Bluetooth Tools on that. So I think the problem is with the XDAII and it's built in SPP support.

Had the same problem, resolved it:
Strange but true, but on XDA2 etc, in order to receive COM Bluetooth, you have to open the outgoing port as shown in the Systems Bluetooth settings (You have to tick it there, too, of course), not the incoming.
Then, as it is blocking, you have to create a thread that listens on the port.
You cannot use RegisterDevice for a port number (in your case COM4)that is already used and open.

OOPS.... and you have to call OpenFile(), not CreateFile() !!!!!!!!!!!

TomTom - GPS receiver with short memory?

Hi,
I've trawled the forum and I've followed all the TomTom setup procedures. The Problem is they seem to be for people who can't get TomTom working at all. I can get it working, just awkwardly.
Once I pair with my GPS receiver and go into TomTom i can get a connection. However when i quit TomTom and turn off the GPS it seems to forget. Next time I turn it on I don't get a connection.
The way I understand TomTom is that it seems to wait for the GPS receiver to contact the phone. This seems odd as I would have thought the phone would be the one to initiate contact.
Anyway my GPS receiver just seems to forget what phone it was connected to. TomTom obviously isn't forgetting the port, windows obviously isn't forgetting the pairing. But Every time I use it I have to re-pair the receiver (thus reminding the receiver of the phone it's supposed to be bonded to). It's beginning to drive me a bit insane.
Anyone else have this issue? Perhaps it's to do with my incoming and outcoming ports? Hopefully someone has already solved this? Not seen any references to it anywhere.

Hello,
Which version of Tomtom are you using ? The last one (5.21) ? If not, try to upgrade and try again.

Yep 5.2 latest release.
I was hoping upgrade would fix it but alas no.

Don't mean to be picky, but 5.2 or 5.21?
I've held off installing TTN on my Wizard, as it works fine on my iPAQ 4700, I have a cradle for that, and according to ttcode, my current device is actually my old 3970, not the current iPAQ... Last week, I had a couple of hour drive to do, so I thought I'd give it a whirl. After an email exchange with TomTom support (who were more helpful than I'd originally given them credit for), I had a new activation code for the Wizard. Here's what I did, from a fairly recent hard reset with no previous TTN install whatsoever. Skip the mail if it doesn't look helpful, but I'll detail my steps in case it helps anyone else...
Although I believe the PC install is mended in 5.21 I copied the map and voice cab files from the CD to my SD card and installed them from there. The GPS drivers and main app I installed from the download I got from the TomTom support site by running the setup util on my PC. Once everything was installed, I moved the maps which seemed to finish up in a sub-directory on the card to the root of the card.
I paired the GPS (my old Emtac BT one) and selected serial port profile. I tried all the offered serial ports in the "Other BT GPS" list in TTN but none worked. Then I went to 'COM Ports' in Comm Manager/Bluetooth Settings and selected "New Outgoing Port". I picked the GPS from the list of paired SPP devices, and it created a new BT COM port on COM6. That definately hadn't been in TTN's list of BT com ports before, but is now there in the list with about half a dozen others. I selected that in the "Other BT GPS" list of BT ports, and TTN connects to the GPS each time.
As I said, I'd recently hard reset the device to try and prove a problem with my BT car-kit soit's quite possible the clean install was the secret, but try creating a new outgoing COM port against the GPS and see if TT remembers that...

Which?
There are 2 general ways to set it up, 1 works 100% (i use it so know it does ) 1 i dont use and have never tried so may well work in the reverse direction and be causing you errors.
The way i set up tomtom; pair the BT GPS. Open an OUTGOING port to the BT GPS, set my GPS as OTHER (wired/cable) NEMA device (NOT bluetooth) in TTN5. now my tomtom connects to the bluetooth, not the otherway round. This method has thrown up no errors for me at all.
If you have followed the reg edit/hack to show the GPS page in connections then i dont know how the settings differ and the possible results this could have on connection issues.
Let us know which way you are going

I have the exact problem as BigDamHero. Each time I wanna use TTN, I need to delete the previously paired BT GPS and then pair it again, otherwise the TTN will just say No GPS Device. I use TTN v5.21 and Wizard with Windows Mobile 5. I tried my BT GPS device on my brother's PDA which runs on Windows Mobile 3, and it connects like a gem every time. I am also looking if anyone has solved this issue, cos it is tedious re-pairing every time.

Had the same problem until 5 mins ago! Found an explanation in another thread, but only in Dutch..
Here's how to do it:
Turn on GPS
Activate bluetooth on device, go to BT parameters, delete previous pairing like you're used to
Create new pairing, choose GPS, enter passkey, check Serial port in services, go to COM ports and add outgoing port (e.g. COM6) like you're still used to :roll:
Add an incoming port too (e.g. COM7) <-- Here's the trick!
Set your GPS apps to use COM6 (the outgoing one)... and here you are! This time it will work, you can turn off GPS and device bluetooth, turn on again and it will connect by itself.
If you want a bit more you can activate GPS panel, set program port to COM8 (then you will have to use this in your apps) and COM6 as hardware port.
Everything works fine now!

hey man, wot a coincidence....i also just read that post which had the dutch explanation.....BUT however, it's not working for me.

I did everything in the list except for creating the incoming port and it still works everytime (I know that's no consellation to you). I wonder if something else you've installed, or the way you installed the app is causing the problem? Is it worth a hard reset and trying the entire install on a clean wizard?
Dox

A friend didn't need the incoming port either. I believe it has something to do with the GPS, as he has a different brand than me.
With mine, before adding the incoming port if I started an app without erasing/redoing the pairing before I would get a notification saying "Navman GPS wants to connect" and asking me to pair. It would keep coming every 10 seconds whatever I did.

BigDamHero, what brand / model of GPS is it?
Maybe we can see if anybody here, or over on pocketgpsworld has been able to make the same combination work and if so, what they had to do to get it to fly...
Dox.

well, tomtom was the very first thing I installed when I got my new vario. it was only after I got tomtom fully working (but still need to re-pair everytime), then I installed a couple of simple Card games.

A quick glance at pocketgps suggests others are having similar issues. There's a thread here that suggests leaving it a while, and I seem to remember other GPS issue threads saying power up the GPS and let it get a fix before starting TTN. A more detailed probe round the forum will probably show more of the same.

I've just flashed my Qtek 9100 to a new ROM, (the O2 one), and since then I've been getting this same problem. With my previous ROM everything worked fine. I was able to turn of either my PDA or GPS, and they would always auto-reconnect in a few seconds. Looks to me like something broke during one of the ROM changes. Which ROM versions does everyone with/without this problem have?
By the way, I have a BT77 GPS.

Hey sorry for the total lack of reply. Been snowed under with exams.
Ok I tried most of what you guys said but didn`t work. BT ports aren't available to select as hardware ports.
However I have managed to solve it. The key was to pair the GPS, and create an UNENCRYPTED OUTGOING port. That's all. Previously I had encrypted ports outgoing and incoming. My GPS applet in control pannel is set to none so it,s nothing to do with that.
I don't know what my GPS is. Its unbranded. One of the cheap common ones.
Hope this helps some people with the same problem.

GPS Control Panel

Not sure if this was addressed before (GPS is too short of a word for the search engine to return any results on).
Does the GPS Control Panel actually do anything on the Hermes? I read that it is supposed to allow more than one software to access the GPS at the same time. I've never actually been able to get it to do anything at all though.
I have a bluetooth GPS. I paired it, and opened an outgoing COM port (COM2). Telling GPS software to access that port directly works just fine. However, if I use the GPS control panel to use COM2 as my hardware port, COM9 as my "Program Port," and tell my programs to use COM9 instead, it just sits there, never even activating the GPS.
In summary:
BT-GPS -> BT on TYTN -> Outgoing COM2 -> GPS Control Panel -> COM9 software port -> GPS software
That above there is not working. Am I missing something?
(Secure connection is unchecked, and letting the software controll GPS automatically IS checked)

Same problem here. Tomorrow when I get some time I'm going to fiddle with the registry and see what's up. I'll post back with my results.
Ninja1

it allows you to run 2 gps application at the same time ie tomtom and memory map for example it usually hdden as unless you are running 2 gps apps its not needed

I would like to run 2 or more GPS apps at the same time. This thing just doesn't seem to actually do aything. GPS never turns on.

Bluetooth GPS Help

Now, do excuse me if i'm having my normal blonde moments but i think i am going to need help before i throw my MDA in the bin for good.
I brought TomTom Nav 6 which arrived today, has gone onto my phone and works perfect.
I already had a GPS Device from when i had Nav 5 and used an XDA (which for me was much better as bluetooth actually worked properly)
No matter what i try, my GPS Device cannot be found. I have paired them the best i can, i have set up an Outgoing COM port on 7 (this is using the GPS Device's name) and an Incoming on 6.
Is there anything else i can try of have i just wasted £150?
Thanks
Cheryl

Hi Cheryl,
Just to try and help you a little, can I suggest the following.
In Bluetooth settings/com ports, delete the port you have assigned to your GPS.
Then delete the GPS from the Devices list and re-discover and re pair it again.
While you are in this paring process, there will be a box labelled "Secure connection", (Or something like that)
Make sure it has not got a tick in it. The secure connection affects the pairing somehow.
When you have paired the GPS, go back to the Com Ports section and tap New OUTGOING Connection and assign it to Com6.
This is what my TT6 is set to and works very well.
I hope that helps.

Thanks for your help, thats perfect and it works.
Do you know why my Active Sync has now stopped working?? I am very think when it comes to PCs. It worked earlier, now it doesnt. In settings it says No Com Ports Available?
Cheers
Chez

Sorry for taking so long to reply.
When you set the com port for the GPS, before you asked on here, you set it to com 7 didnt you?
Ok, if so, have you made sure you have deleted that from the settings??
i.e: You should only have Com 6 set for your GPS and no others.
Other than that, I wouldnt know what to suggest, sorry.

Bluetooth problem

Trying to get navigator to work and got a pairing problem. For some reason I cannot select com ports apart from 0,2 and 8. All the others it says " The com port could not be created. Please check your settings and try again.". I only have a bluetooth headset paired, but surely that is not using all the other ports. TT won't also allow me select other comp ports apart form 6, which I obviously cannot set up.
? Is there a check to see if the GPS receiver is paired succesfully without using TT. All the lights seemto show they are communicating, but TT can't see it.
? is there a program that can be edited in the software to force a com port to be used.
Sorry for what may be trifling issues, but any help appreciated
