Multiple Bluetooth Devices

[Colonel Klink]

Hi there guys, its been a while since posting but I have some great news regarding using multiple bluetooth devices in the car.

A few weeks ago I purchased a Navman 4410 GPS unit for my XDAII. With the new "72" rom the Navman worked perfectly with my XDAII straight out of the box over bluetooth.

Today I installed a Sony Ericsson HBC-30 bluetooth hands free carkit (Which also worked perfectly out of the box). I was interested to know if I could have the GPS unit operating and have the handsfree carkit working at the same time.

I was simply sitting in the carpark, with the GPS connected and onscreen, then I used my other phone to call my XDAII... the call came up on screen (interrupting the GPS screen) I pressed the "answer" button on the Sony Ericsson handsfree kit, and the call came through perfectly!
Once finished with the call I pressed the "hangup" button on the handsfree kit, and then a few quick taps on the screen returned me to the GPS navigation screen.

Certainly not perfect, however it appears that the bluetooth issues are finally getting resolved, and allowing us to begin using the XDAII as it was intended.

Hi Colonel, thanks for your update, it is comforting to know that they are finally sorting out BT problems.

Is there any way to get the phone screen to automatically close after finishing a call? so I don't have to manually close it to get back to my GPS screen?

[Colonel Klink]

No I dont think you can. Not without altering the GPS software to continually make sure its "on top" of other windows... but then you'd have a problem with seeing the "incoming call screen" as the GPS software would try to jump on top of it.

I'd be so happy simply if I could make HCB30 and Blutrek G2 headset work side by side on my Qtek... :(

[alecxda]

points are:
1-where coul i get that da***n 1.72 rom for my xda 2
2-where could i get the g2 HS in italy(even worlwide...) or all over the web at reasonable price

help a newbie... :oops:

Kolonel,
I can confirm your experience as far as BT GPS is concerned.
I however still have one issue to solve: When the MDAII (=XDA2) can't connect to the GPS (BT off, GPS off, GPS out of reach) and I start TomTom3, TomTom3 keeps searching for the GPS which results in a almost freezing MDA2.
Using rom 1,72 from Qtek I bonded the BT GPS and confirmed the question about assigning a com port.
In TomTom I assigned this (COM5) com port.
All works fine except for the issue mentioned.

Does this sound familiar?
Clues?

BTW in the BT settings screen there is nothing shown about the assigned com port (just free space next to the two lines that should indicate the in- and outbound com ports). I found COM5 to be assigned to BT by trial and error . . .

edsub,

Are you using "Bluetooth Tools"? Because I am not, i'm using the native bluetooth stack only.

I am using "Outbound" Com port 5 ONLY for my GPS. My 1.72 rom is the IMATE rom.

Im afraid that i'm not familiar with tomtom. So I cant help you there, sorry.

[edsub]

I am deliberately only using native MS bT stack.
I am only using COM5 for GPS too

What does the BT Settings show under
"Bluetooth Serial Port Setup"?
With me:
"Outbound COM port" checked, but after the colon is a "<not present>" shown.
"Inbound COM port" UNchecked, after the colon is a grayed-out "<not present>" shown.

Like i said I AM able to use the GPS via COM5.

Maybe this issue is a pure TomTom issue, I think your answer could clarify that.

Edsub, thats really weird... mine is:
"Inbound COM port:" UN checked, and after the colon is a grayed out "COM4"
"Outbound COM port:" checked, and after the colon is a black "COM5"

hi guys

im using imate 172 and tomtom 3 with a sony ericsson hb35 it works first time all the time with the standard stack. it works that good i even went and sold my carkit and just got a hold instead :lol:

@Kolonel Klink: I guessed it's strange. What ROM are you using exactly (OS & Extended).
I use the 1.72 Qtek rom with my own Extended Rom (wich is based on the Qtek ExtRom to which I added T-Mobile Nl customisations). I am sure there is nothing regarding Bluetooth in my ExtRom.
I heard from someone who uses the iMate 1.72 OS Rom (with his own cooked ExtRom) that he has the same results as you have.
Just trying to find to cause of this. Maybe I have to reflash to the iMate 1.72?? (shouldnt make a difference as both iMate and Qtek OS ROM's are the same 1.72.00WWE . . . .)

@freelockuk: Most interesting is the origin of your ExtRom. Arent there any Bluetooth enhancements in that ExtRom (like there were in the 1.60.36 T-Mobile NL ExtRom) that maybe make your 1.72 work better than mine concerning Bluetooth?

addition to prev post:
I noticed that there were two BT registry settings missing to get the assigned COMport show in BT Settings.
Also noticed another interesting value:
[HKEY_LOCAL_MACHINE\ExtModems\bluetooth_dun]
With me this one is:
"port"="BSP9:"

In prev versions it was:
"port"="BSP4:"

Can anyone with a 1.72 ROM that has a BT GPS mouse working via SPP AND who can start Tom Tom without the BT GPS mouse 'connected' post their setting of this key??

[Colonel Klink]

Okay, i've not cooked my own extended rom. I'm using the stock standard one from iMate.

I did find something odd today. I went into an IT expo and I turned flight-mode on. When I was finished I left and turned flight mode off. Then got in my car. I tried to make a call and it didnt go thru the handsfree kit.

Weird! I had to repair the device. So I did... and it all worked fine again. So I turned flight mode back on then off, and I ended up with the same result. It appears to lose the pairing when you turn the flight mode on.

Very odd!

I still have not found a solution to the behaviour where TomTom locks up the MDA with is isnt able to connect to my BT GPS.
Today I found out that this same behavious accurs on devices (not just MDA, HP too) that use a serial (wired) GPS when they take the current off the GPS . . .

That means:
1. TomTom Navigator can't cope with the situation where it cant connect to the GPS that is installed
2. With me TomTom navigator is not able to use the Bluetooth protocol on its side to cope with the (for Bluetooth GPS quite usual) unavailability of the BT GPS.

Again: Can anyone post me some info on this :?: :?:
Especially the registry items under
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\]

[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Se rialPort]

[HKEY_LOCAL_MACHINE\ExtModems\bluetooth_dun]

[HKEY_LOCAL_MACHINE\ExtModems\bluetooth_dcn]

are of interest

@ Klink

Thanks for sharing your experiences, I'm watching them with interest.

Just wanted to as you about using your navman and the headset at the same time.
In your first post to this topic, you mentioned your 'carpark' test. I assume you weren't moving at the time, so the navman wasn't trying to give you directions.
What happens when you're driving along, getting instructions (ie. "turn left in 300m") from your navman, and the phone rings? Does the navman stop giving directions while you are talking on the phone using your BT handsfree? When you hang up does it resume giving directions again?

Thanks,
Hooligan

Like all of you my exprience is that it all works together.

But I've one problem. When navigating with TomTom and there is a incoming phone call and when I accept the call with my headset TomTom continues navigating but the sound of my QTEK2020 is muted during the call. So the instructions of TomTom cannot be heard.

I'm using plain MS BT Stack.

Regards,
Mark

[edsub]

This behaviour seems not the be dependent of the use of a BT headset. I have a carkit and during a call TomTom stays active in background. Sound of TomTom is muted however, which I find nice.

When the phone call is ended, TomTom starts talking again.(also nice)

[sparkal]

first of all my nevigation program works great with the jabra 250 bt , it also mutes the program during a call is madeqreceived but :
there is anothe program that is called "ontime" that sends trqaffic status to the imate, using the gprs andthen calculates the fastest root( from junction to juction) and the problem is:
if i want to use buth progtams with royaltek gps bt rbt1000 they both need the com5 port fot bt.
to solve this problem one can use a prog called: "gpsgate" which makes a virtual port for the programs to use so u can use several program with one bt device.
for some it works only with bt tools, for others it doesnt work at all, gos knows why?!
but - if any1 needs a solution - here is one.

have a nice day , spark
QTEK 2020 - 1.72.00 WWE - 1.06.01
Back Pack - jabra 250 BT- royaltek rbt 1000 GPS BT - DESTINATOR3(LIKE TOM TOM 3) - soon will recieve sd 1gb*40

[edsub]

Spark, where did you get 'gpsgate'??
