Problem with Bluetooth SPP... - General Topics

Hello,
I'm a last year student engineering, working on my thesis. I wrote an application for my phone (Rhodium, but doesn't really matter) that can connect my phone to the hardware I designed, using an Serial Port Profile (Bluetooth). This works, but the problem is that any baudrate higher than 57600 crashes the application... The Bluetooth module I used on my hardware can be configured for 921K, and I really need that speed! The connection is just toooo slow right now. Does anyone know what the problem might be? Is SPP limited to 115200 baud? This seems unlikely, because I can configure the module with speeds that are much higher...
I would really appreciate it if someone can help me!
grtz,
Bert

Nobody who can tell me something about it, or know where I can find more about this?
Grtz,
Bert

at& fuse gps problem (not the lag/strength related kind)

ok so i bought an att fuse and like everyone here mentioned about hang ups, weak signal, etc i thought i would just use my old external bluetooth gps unit.
so breifly here is the problem, it works fine when i use a single application like google maps. but when i try to put the information in the external gps app (start>settings>external gps) i have my problem.
under the hardware section, it states:
Specify the hardware port to which your GPS device is connected.
i do so click ok and nothing.. so i go back in to see whats wrong and the gps hardware port resets its self to "none". its as if the settings never save or reset them selves. i know on my old phone (tytn) this would be somthing i considered unusual (so i am kinda familar with the mobile) os.
i am not sure if there is somthing wrong with my handheld or if at&t has some kind of block?
anyway i tried to use the forum search and really didnt turn up any information so any help would be great i really like this phone.
thanks in advance to anyone that can help.
I've never had those settings stick on any of my WinMo phones.
You don't need to use that to use a BT GPS puck anyway, you set the COM port in the Bluetooth settings.
It won't let you make a selection from that drop-down because the GPS hardware does not function by exposing a COM port as with standard hardware, it exposes a GPS0: port, that is picked up by the GPS ID, and exposed to the system as COM4:..
Now because the GPSID has been replaced by HTC's version of it, it's designed to work only with their internal GPS. If you want support for an external GPS in the GPS ID, you need to cook the stock Windows Mobile driver back into the ROM..
That being said, you don't need the GPSID unless you plan to have multiple programs connecting to the GPS at once, so you should be able to squeek by..
thanks guys i knew i would get a respoce here. unfortunatly i was hoping for a easy solution to use external gps with multiple apps i see unfortunatly its not possible without alot of work.
at any rate i am still very hapy with the device i was debating on upgrading from the tytn amd so glad i did =)

TMC usage with iGO8

Has anyone have any successful experiance with iGO8 using TMC on a PDA?
In short- I have a GNS trafficbox TMC reciever. I have iGO8 R3 and I ahve a P3600 (trinity) phone. The phone has WM6.1 operating system..
Trying to config it to be able to identify the hardware (it is physically connected to the mini USB on the phone there are 3 variables. TMC protocol (I assume GNS) , COM port, and baud rate.
I have tried any combination possible (including all auto) and get one result- 'NO TMC hardware found'
Does anyone knows how it can be configured? Another 'rumor' I read on the forum is iGO8 8.3.x does not have a working TMC at all, and that 8.0.x recognize the hardware but nothing further.
I know it is more an 'iGO' question than XDA, but it is related, and this forum is the only forum I know with responsive people and knowledge.
Thanks in advance

I've emailed NavNGO Israel about this as i wanted to use a special positioning system for a friend who's in the military.. unfortunatly, I would have to tell you that unless someone found an unformal solution which I don't know about, you will have to give it up.
you can use a TMC with bluetooth tho... http://www.gns-gmbh.com/index.php?id=72&L=1

[Q] Running TomTom on the TG01?

Is there a version of TomTom that runs without GpsGate?
My TomTom does not find the GPS receiver of the TG01, i.e. i need to run GpsGate for TomTom to find a NMEA source.
Is there a TomTom version available that can directly see the built in GPS receiver of the TG01?
thanx!
No, you always need a 3rd-party-app with TT. Serach for GPSModDriver (i recommend 2.60). This prog runs in background, so you donĀ“t have to start it before you use your TT.
i first tried gps mod driver, but this seemed to be some kind of instable (sometimes it worked, sometimes not). so i switched to gpsgate, which seems to work well.
as gpsgate is always running in background, i suspect that it keeps the gps receiver running even when the TG01 is in stand-by, and this might be a reason for the battery to discharge that fast. therefore, i would like to get rid of this intermediate tool.
is there no way to directly access the gps receiver from tomtom?
how can i see if the gps receiver is running and if it is powered down when the TG01 is in stand-by?
thanx!
Use iGO instead

TomTom simply doesn't support the TG01's internal GPS receiver without third party software.
Needless to say I ended up switching to iGO Primo which does support the internal GPS receiver on the TG01 when you insert the attached INI file into the Primo's DATA.ZIP file.

i've got NDrive with my TG01, i.e. this looks like an alternative to TT. but unfortunately, this does not read TT POI.
as i need to use TT POI, i think there is no alternative for TT
Use Gpsplex with TomTom- it works well and is free
my main reason to get rid of gpsgate was power consumption.
it looks like as long as gpsgate is running, the gps receiver of the TG01 is running, and the battery discharges very quick. besides this, gpsgate works fine.
i suspect that using gpsplex won't help, as this will keep the gps receiver on permanently too. i.e. the only way to go seems to start gpsgate (or gpsplex) before tomtom - and after using tomtom, the gpsgate (or gpsplex) has to be killed.
This problem has been already solved properly, in my opinion.
I don't know if you examinated the Mortscript route. Anyway...
I made a script (as many others did) that does this:
when tapping on script
-turn on GpsGate
-turn on Tomtom and wait
-when Tomtom exit close GpsGate
So, this way, the use of GpsGate is totally transparent and it consumes battery just as any other navigator does.
For me it's even better than running a navigator that turns on GPS by itself, because my PDA when in car profile and externally powered turns on GpsGate automatically. In this way whenever I need Tomtom I can turn it on and have instant fix.
If you know about this, than I have no other solution, while if you are interested I can give you more details (and the script, of course)
my 2 cents
hey, that's great!
that's what i first thought about, but i didn't think that i would be able to start and kill gpsgate from a script!
(i haven't used mortscript for years, but i think i still have it somewhere)
so it would be great if you could post the script!
thank you vey much!!
ok, this is the script:
if ( NOT ProcExists("GpsGateCE.exe") )
GGOff=0
Run( "\Programmi\GpsGate 2.0\GpsGateCE.exe" )
else
GGOff=1
endif
RunWait( "\Storage Card\Programmi\Navigator\TomTom Navigator.exe" )
Sleep( 1000 )
if ( ProcExists("GpsGateCE.exe") AND ( GGOff=0 ) )
Run( "\Programmi\GpsGate 2.0\GpsGateCE.exe" )
Sleep( 200 )
SendUp
Sleep( 200 )
SendCR
else
endif
Some explanation.
If GpsGate it is NOT already running it will be closed after Tomtom. If it is already running it will be leaved on because if I am in the car when I've finished with the navigator I still want GpsGate locked on satellites while I am driving.
This is just to let you quickly deal with the Tomtom problem. So, please, modify the script to better meet your needs.
It's very late for me now, and this weekend it's unlikely that I came back to the forum. So sorry for the short response but I have many more things to say on this. The script can be optimized, for example. And I would also tell you more about commands SendUp and SendCR.
Please, came back in this thread. I'll find time to give you more usefull informations. In the meantime begin to test your script and ask for difficulties you could encounter.
Cheers
P.S.
Please, remember to localize the path of your applications!!!
thanx very much!
i think this is exactly what i need, and i'm quite sure that i'll be able to adapt this for my needs
as i'm away now for 1 week, i will wait to check this out until i'm back.
i think there's no need for futher explanations. if i can't get it to work, i'll just ask again
thank you very much!

[Q] Help setting up passive bluetooth connection

Hi guys.
Not sure if this is the right forum to ask this question in, so if I have it wrong I apologize. So as the title suggests, I need help to get my Samsung Note 3 to passively connect to a HC-05 bluetooth module (tried putting a link to the product manual, but I don't have enough posts to do it yet. My apologies if you need to Google it).
My goal to to have the phone passively connect to the HC-05 in the same manner it would to devices such as bluetooth car kits, headsets and so forth, i.e. to automatically build a connection with the module whenever it is in range. It doesn't have to do anything other than simply connect. At a later stage I will work on sending commands to the module, but for today I just need to sort out this auto-connect problem.
I've tried setting the module to master mode and then binding the module to the BT address of the Note, with the hope the module would actively search for the note and connect to it whenever the note came within range. That approach however that didn't work, and I have again set the module back to slave mode and have been forced to use BlueTerm to build the connection. This has me now believing the connection must be built from the Note, and the module has to be the slave to it, as when I use BlueTerm it works flawlessly every time.
Surely somebody out there can point me in the right direction to accomplish my goal.
Any help is greatly appreciated.
So in the entire XDA brains trust, there's nobody with any idea how this can be done?
Still nobody has any ideas?
Still nothing? Really!???

use phone as usb or bluetooth headset

Hello,
as you can see on the title it pretty much describes what I want to accomplish.
Now, before you go "just google it" I have tried with the solution to install soundwire, but the wireless is too bad for the telephone, the computer comes first it looks like, so I can't do that.
I have gotten "WO mic" to work properly as it should, I only need help with the speakers for my telephone.
i would love to accomplish this without using Wi-Fi, and either with bluetooth or USB connection, if it would be possible, or is it still not possible after the 5 year old thread I read said that it is not possible to accomplish such thing through bluetooth/USB?
Thank you for taking your time reading through and trying to help me, much appreciated!
// Anders
Edit:
the solution in this thread is what I tried, but it does not work either.
