Hey all Iv been browsing these forums for awhile now but never did register but this seems to be the most active community on this humanoid that I can find. So naturally i figured this would be the best place to post my question.

I just recently came into possession of the bluetooth module for this robot. Except my module is a little different then the one listed here.

My bluetooth adapter came with the module that solders onto the Robobuilder board, and then there is a base station which has an identical bluetooth module on it which then plugs into power and the serial connection cable that comes with Robobuilder. The base station also has 4 servo ports on it.

The problem I'm having is how can I pare Robobuilder with the bluetooth that is on my computer rather then use this base station. With the base station I can get it to work fine along with the Serial to USB converter. But I would much rather eliminate the need to have all these extra wires and the extra board.

For some reason I can't get my bluetooth dongle to find the chip on Robobuilder. Is there a special way to pare these or am I just totally missing something?

The bluetooth dongle I'm using in my computer is this one

Any help is greatly appreciated I will continue to fiddle with this and see if I can get it to work.

Hi chaps,

I recently made some research about the possibility to connect my AVR development board (Equipped with a Uart Bluetooth module) to my cheap NOKIA 5000. Due to the fact that my mobile phone supports Java and Bluetooth I decided to search for a java based Bluetooth Terminal Software. While browsing the Internet I did not find any Java J2ME based application which can act as a Bluetooth Terminal (like HyperTerminal). I have decided to develop this Software myself and now I have released version 1.0 of my Cell phone Bluetooth Terminal Software called BTTerm.

BTTerm Features:

* Java J2ME application works on almost any mobile phone with Java.
* User input by a textbox or directly in the Terminal by using the phone keyboard.
* Tested with Bluesmirf and BTM-222 Bluetooth modules.

No - the 2 wire unit only supports wifi connections.

You could possibly connect both laptops using bluetooth, and then extend the internet connection from the one connected to the router.

How Can a usb bluetooth adapter connect me to my wireless router? I have a 2wire modem and i have one of my computers hooked up on it. But, I have another computer with windows XP and i want to know how to hook it up wireless with the bluetooth adapter. Is this possible or is bluetooth adapters only for bluetooth.

Hi Atom182fr

I have another suggestion:

You can use Microsoft Robotics Studio to create a simple program that uses the Remote to control Robobuilder.
(create a program that does the same as the program you were using).

There is a very nice manual from Robobuilder about using Microsoft Robotics studio so I recommend that you have a look here:
http://robosavvy.com/RoboSavvyPages/Rob ... torial.pdf

It also works with Bluetooth and you can even use other functions such as voice commands to control your robobuilder.

My suggestion is that you go through the manual and learn about MSRDS step by step following the Tuturials mentioned.

Regards
Pedro.

Hi Atom182fr

From the video, I am 99.9% sure the problem is caused by the Bluetooth device drivers in your computer.

The only way windows can have a bluescreen is when it's caused by a device driver because drivers run in Kernel Space.

Therefore I suggest that you check what is the Manufacturer of your Bluetooth Dongle in your computer and then go to their website to download updated Drivers.

This seems related to the Bluetooth dongle you have IN your computer; not the software you are using.

Regards
Pedro.

I updated DirectX as requested .. nothing has changed. I tried to do it on another computer.

Here is a video that shows my pb:

one action with the lever and boom it restarts..

I reinstall the drivers several times .. the problem remains the same. Oh what a shame! .. lol

Hi Atom182Fr

If the problem only occurs when you use Bluetooth, then it could be one of 2 things.

What happens when you try to use Bluetooth?

1) The computer shows a Bluescreen and then restarts?
If this is the case, the problem is caused by the Bluetooth drivers in your PC.
You will need to look for updated drivers for your PC, in particular for the bluetooth on your PC.

It could also be a problem of Direct X (although I sincerelly doubt because the joystick works fine without the Bluetooth).
In any case, if you want, try downloading and installing the latest version of DirectX on your PC
I think the link is this http://www.microsoft.com/downloads/deta ... laylang=en

2) If only the program closes (but the computer does not restart) then it is a bug in the software.
This was never seen before in a scenario like the one you describe.

Another thing you could do is try to use the software AND the Bluetooth on a different computer.
If this works on a different computer then it's for sure the problem I described in 1).

Pedro.

that's it .. for your questions, the software works very well when I do not use Bluetooth to connect the robot to the PC.

by cons I do not know how to use script and even less write them .. the problem must come from the software key .. but I do not know how to remedy it. I am on windows xp sp3.

Hi Atom182

So if I understand correctly:
- Robobuilder talks to the computer with Bluetooth
- Your Xbox controller is connected to the computer with a cable (not with Bluetooth).

A few questions:
- Does it work if you use the Serial Cable and not the Bluetooth connection?
- Does it work if you use Bluetooth with Robobuilder but a different Joystick?
- Does it work with Bluetooth if you use the program I mentioned http://robosavvy.org/forum/viewtopic.php?p=19511#19287

From my experience it is probably a problem caused by your Bluetooth drivers in your computer.
The Parani ESD200 Bluetooth Module that we sell for Robobuilder is a standard Bluetooth device and is widely used in many applications.

With regards to the possibility of being a software bug, full source code for the software is included so you can make the bug fixes yourself (if that's the case).
The software is contributed as a gift to the community and is not officially supported by Robobuilder.

There is another alternative to develop the PS2 remote control which is using .Net and the libraries by l3v3rz which are very good.

Regards
Pedro

Excuse me, I speak badly. I use bluetooth only for connecting the robot to the computer. my Xbox controller and connected by cable .. I use only one key dongle.

Robobuilder connects the well to the computer. is when I use the software that there is this problem ..

Hi Atom182Fr

For troubleshooting:

1) To determine if the problem is caused by the software I wrote or the drivers for the BT dongle, please use the program available here http://robosavvy.org/forum/viewtopic.php?p=19511#19287
It is a small VBScript tool that talks to the robot using the commands you give on the keyboard (no joystick)

2) If you have a normal PS2 controller (not Bluetooth) I would recommend that you also try the program with this controller instead of the Bluetooth controller.

As a final note, most BT stacks require that you first pair the devices (the dongle with Robobuilder) and, after that, on the Bluetooth manager tool, double click on the comm port or do some trick to manually establish a connection to robobuilder.
Once the connection is established you should be able to use the software normally.

- What model of BT dongle are you using?
- Are you using two dongles on the same computer (for example the built in bluetooth and an external/additional dongle)?

hi guys!:roll:
I will explain my situation: I purchased the bluetooth module for the robot and a key bluetooth dongle v.2 for pc. I'd like to use this equipment to control my Robobuilder by my pc.

I install the module on my robot and the key on my pc. so far so good .. the module works perfectly. that's my problem: when using the software made PedroR to control my robot with my PC, I plug my Xbox controller port and bluetooth robot. and when I do an action, the computer crashes and restarts.

it may be a problem with windows xp .. or with the key bluetooth dongle v.2. in any event I buy on the site, so I'd like to understand how it works ..

if it has happened, you can help me.??

thank you to you

to control the robot from your phone you will need to write some software on the phone.

The Bluetooth module only offers a comunication channel from the device to the robot.

It is quite easy to write a program to control the robot (similar to the one i wrote for the PS2 joystick).

You just need to follow the protocol available here http://robosavvy.com/RoboSavvyPages/Rob ... ommand.pdf

In essence you only need to send a sequence of bytes to emulate a Remote Control.
The sequence is always the same (only the last part changes) so it's quite easy to implement.

You can implement it on any device that has Bluetooth (not only your phone) as long as it supports the Serial Port Profile and you can program it to send this sequence of bytes.

Regards
Pedro.

hi atom182

I don't recall the exact code but I know that, if a code is requested, you need to use a DEFAULT code. Please try the following:

- 1234 (I think it is this one)
- 12345
- 0000 (4 zeros)
- 00000 (5 zeros)

I believe the correct code is the first one.

Please let us know if it works.

Regards
Pedro
