Hi,
I am having problem in executing AT commands on my XDA.
Here is what I did:
1. I connected my XDA with the bluetooth on the Computer, which gave me COM8 to communicate.
2. On Hyperterminal I connected to COM8 and send "AT+Enter" gives me nothing (should give me OK, I supppose).
3. I tried several baud rates, but in-vain.
Anybody could help? Really appreciate.
please ask questions in the Questions & Answers section of the forum
thanks

Hi all,
I just written a eVC program to open the COM1 port and send commands to barcode printer. It works fine in iPaq, but for XDA, it can open the port, but seems no signal sent to the barcode printer.
In fact, at first, it can't open the port since I haven't unchecked the beam settings. Any other things need to do to make it work? thx!

I wrote this test program to do various things with io ports.
on my xda I can open com1: with it.
There's something funny about the XDA serial port. It seems to need signal on some of the incoming signal wires to come alive electrically, independent of whether the port is open or closed. Probably some kind of power-save feature, but it can be damn annoying sometimes.
Try looping back some outbound status lines into the incoming ones until it works.
Thanks for those replies
Just want to give more informations!
Actually, My configuration is as follows:
xda -> serial cable -> null modem -> printer cable (which originally used to connected to PC serial port) -> barcode printer
So, for ipaq and xda, this part "null modem -> printer cable -> barcode printer" are both the same, the difference are just the serial cable ( one for ipaq and one for xda). To test if my xda serial cable works or not, I have used it to connect xda to my PC. The signal received in my Hyperterminal looks OK. Thanks!

PC does not recognize xv6600
My PC does not recognize xv6600 when it is plugged in. No New Hardware.. window appeares.. Any suggestions?
Hi fellow Xda-devs,
I'm a software engineer.
I do alot with honda ecu software. This goes for programming and datalogging. The problem is honda talks TTL. I have an ttl->usb and ttl->db9 serial.
I really wanna use my app i created for pocket pc. I'm gonna buy a wizard now, i had an qtek s100 first. Both don't support serial port nor usb host stuff. I use a pl-2003 chip for usb->ttl. Which has a pocket pc driver.
I'm think of buying a BT->serial. So i will use BT->Serial->TTL.
This is a link i have found.

BlueTooth to RS232 adapter - Help with strange requirements.
I have also been looking for a bluetooth RS232 device. All of the devices I have found meet my basic requirements. Though, a couple of applications that I planning to develop, provide me with a couple of out of the ordinary requirements:
1) I own a MAS-TECH multimeter which has an RS232 connection for logging reading on a PC. The connection operates at 600 baud (600,n,7,2). All the bluetooth devices I have found only go down to 2400 baud.
2) I also need the device to support baud rate changes on the fly. I would like the AT+IPR baud rate command to change the baud rate of the bluetooth device, once the command has been sent to the destination device. All the bluetooth devices I have found support a range of baud rates, but can only be configured using specific commands or via an application. The worst case I have found is that the device requires a reboot following reconfiguration.
Does anybody know of such a device?
Anybody have any suggestions?
Hi everybody...
I know this has been posted be4... but I have searched the forum a lot, with no luck..
searched howardforums too.. no luck too...
even in bengalboy web site, but his guide did not work.... every time I try to connect to my pc I get disconnected..
I wish to sync vis M$ stack... not Bluesoeilfor the JAM
I has MSI BT dongle, Toshibal BT stack on PC, M$ BT stack on JAM
*PS: does anybody know how to install M$ BT on PC... I have Win XP pro SP2.. and I think it should have built in.. but when I uninstall Toshiba's Stack.. I can get anything!!!
please help...some basic what to do....
I really appreciate it
duke911: do you want to explain what you've done so far on the PC.
That PDA should be fine, it's quite easy to setup
(read here:
http://forum.xda-developers.com/viewtopic.php?p=144696#144696)
However, on the PC: you've installed the hardware, have your bluetooth dongle working, and have successfully paired your PDA?

Thanks vijay555 for the swift reply :wink:
The dongle works fine, pairs and everything...
but when I plugged it for the first time.. it was not recognized by my PC... aparenely there were no drive for BT.. so I installed the Toshiba's stack bundled with the dongle.
Here is what I have done:
first I tried bengalboy guide here ( although i dislike his website a lot )
http://www.bengalboy.com/modules/newbb/viewtopic.php?topic_id=4&forum=8
but every time I finish and I press Connect Via Bluetooth in Active Sync PPC... I see the opening port message etc.. but I don't get connected..
after that.. Toshiba's Stack on my PC started to act weired... first when I paired with the JAM.. I get three services: SPP, DUN, Push Object
but after a while.. SPP just disappeared...
Then I uninstalled the driver.. reinstall.. same problem..
uninstall.. tried ( Add Hardware Wizard in PC ) to try Microsoft Stack.. but it did recognize the dongle...
please vijay555.. can you tell me how to install the original stack from Microsoft on my PC???
Thanx in advance
duke911: I'm actually using the blue soleil stack that came with my ebay dongle. I vaguely remember there being an enormous effort getting that to install, for marginal benefit. I'm in the office right now, but if you still need help later I can see if they'll help you out, when I get home later.
But try reading through some of the blue soleil threads on this board, I think they discuss the relative benefits of the various stacks floating around on the board. Blue Soleil works for me, but frankly, bluetooth is the kind of thing you shouldn't have to think about, it should just work, right!? Those threads might also discuss uninstalling any other stack. If you've not made major changes, have you considered using System Restore on your PC to roll back to before installing the dongle?
V
OK.. I have done every thing you can imagine.... it now 2 am... I have been trying to figure out how do this since 3 pm... and no luck :evil:
I tried installing the dongle on a different PC with XP SP1... also no luck.. no M$ driver... so I installed Toshiba's...
after that I restored my JAM using a sprite back up to a different time... how knows maybe i messed a lot since 3 pm
after that i did the following:
1. in PPC: went to Start>Settings>System> Bluetooth Settings then choose Incoming COM and pressed Start in the middle of the page..
2. paired with PC.. no problems.. PS: PPC did not say that my PC supports SPP
3. on PC.. choose the same COM port that Toshiba uses for SPP ( which is COM 8 ) in my case..
4. from PPC tried to Sync.. and then I get this message in Active Sync in PC
5. If I choose different COM port for AS.. I get the usual message on my PPC ( connecting to Host ) but I get nothing
PS: I'm using Active-Sync 4.1 on the another PC... while the previous uses v 3.8
please vijay555 help me out here... my head is about to explode
Problem Solved.... 8)
Will post instruction tomorrow.. step by step.. for newbies...
thanks vijay555 for you help
OK here is the thing...
the trick is to chooses the same COM port for you Serial Port Profile for both : PC bt stack & Active-Sync... i.e. both use COM 7 or 8 ..etc
second.. you should pair your PPC with PC.. and create an Outgoing COM from your PPC...
a picture is worth a thousand words.. check this GIF
cheers
hey duke what did you do? i've been trying to get m jam to sync for agees without any luck! i'm starting to think that it might be the usb dongle that i'm using on my laptop! bout to go buy a new one so any tips you can offer would be great
do the following:
1. make sure PC bluetooth stack uses the same port for SPP as well as Active-Sync i.e. Both COM 8
2. on PPC: go to Start>Settings>System then choose Bluetooth Settings... and then tick outbound COM Port..
3. a pop up message will show.. click OK then you'll be take to BT manager.. you have to make sure you device is discoverable... then pair with your laptop.. after you finish.. go to COM Ports in BT manager... and create a new outgoing COM port...
4. go to Active-Sync in PPC and then choose tools>Connect via Bluetooth
that's it.. and I guess the gif will prove helpful
cheers :wink:
Ok, here's another manual. You have to follow each step precisely!
In your bluetooth manager on the PC, check for your incoming serial bluetooth port. This is the com port number which is shown under Local services or incoming services. If your COM port number is above 10, ask what to do then - ActiveSync doesn't work with COM ports above No 10.
Go to the ActiveSync settings on your PC and set the check box for the serial port. Select the one that was shown in the blueototh settings as incoming BT port.
On your Pocket PC, go to the Bluetooth settings. Select both checkboxes for the incoming and outgoing COM Port.
There you press start, go to your bluetooth device list and delete an existing pairing to the PC to which you want to connect to. Then re-pair the PPC with the computer again.
Afterwards, you can go to ActiveSync on your PPC and select "Connect via Bluetooth ...". That's it.

hey dandie! what do i do if my pc assigns a com port of 11 and higher for my jam? i've tried the "show hidden" under device manger but my pc still keeps assigning a com port of 11 and higher?!
help
thanks
The COM port of PC and PPC DOESN'T have to be match. (No matter what BT stack you are using) In fact
Com port on Magician is FIXED at Com 5 and there is nothing to configure regarding the Com port over there.
On the PC, the BT stack choose whatever free com port them for serial connection. (eg: The blue soleil stack will tell you which com port is using in the pops up message when U BT activesync yr PPC to yr PC)
Then File > Connection Setting and select that port on yr PC's activesync.
(Sometimes, U have to try it serveral times to get activesync working)
So what do we do if our pc bluetooth com port is 85? help please someone.
everything goes fine untill i try to connect jam to pc via bluetooth and as, it comes up with msg connecting to host and does nothing else!
all right i've looked around and found how to remove hidden com ports, but now when ever i pair my jam and pc together the pc chooses a com port of 11 and higher for the serial link to the jam! i cant find any way to get the pc to choose a com port lower than 11 for the serial link to my jam, and from what i've read AS requires a com port of 9 and less!
some one please help this is just driving me nuts now! i've followed all the steps and upon sync through AS on the jam a error window appears saying "Cannot start communications with the desktop computer. The communications port is not available. Another program may be using the port, or it may not be valid.
Quit any programs that may be using the port and reconnect. If the problem persists, restart your device using the instructions provided by the manufacturer."
help please
check this first

I believe you have some hardware using all ports from 1-11 so you may try to change the ports these stuff're using....
cheers
thanks but seen that already! i need to know how to get my pc to assign a com port lower than 11? i've tried the "show hidden" under devie manager and deleted about 87 unused com ports but my pc still wont assign a lower cm port!
anymore ideas!
coz i'm stumped
Hello everybody,
first of all, I want to apologize myself for my questions, because they are often discussed in several forums (USB-RS232).
BUT I did not find a solution. Sometimes I found "it works" and sometimes for the same problem "no chance". Enough ;-)
I'm writing a program in VB.net to log
1) all data from the GPS at COM4 and
2) all data from an acceleration sensor which might be connected via the USB-Port of my XDA Orbit (HTC Artemis).
Logging the GPS-data is no problem excepted the speed of the Sirf star III Chip. Can it update faster than 1sec?
My main problem is the connection to the sensor. I know that port of the XDA is an USB-Client. The data I receive from the development-board is sent via RS232-out.
My question:
Is it possible to get those data-strings into the xda to log them via the existing USB-port? How can I implement it?
Can I connect the USB-plug and the RS232 like I found several times in this forum? Does it work???
The solution of this project is very important for me.
For everybodys help, I am very grateful.
Thank you very much.

If I understand you correctly, you wish to connect an RS232 output to the mini USB connector on your device and log the serial data coming into the USB port? Yes, this is possible, but not without a PIC microcontroller in between. RS232 runs on, IIRC, +9v/-9v, while USB runs on +5v. If you directly plug an RS232 output into your USB input without anything in between you very well might fry your phone. I don't recommend it.
Fortunately, RS232 to USB devices are easily found, both schematics and pre-made adapters.
A quick Google search found this schematic:

Hi fluxist,
thank you for your answer. It sounds very good to me. But does it work with an USB-Client-PDA?
Thanx a lot.
