Bluetooth ache

[hibbo]

Good evening people.

Right then here we go.  I have a bluethooth module HC-07 and have been trying for a while now to get it to work with my Crius SE.

On the adapter there are VCC, GND, TXD, RXD connections,  I have tried to connect these in different variations to the TTL and the FTDI connections on my board.  I can get the bluetooth module to connect to both my computer and my phone but cannot get any readings on wingui.  My bluetooth is on port 40, I have tried to connect directly to the bluetooth using the Arduino serial monitor on every Baud rate and I cannot get any feedback.

Any more info needed please ask.

All help much appreciated.

Thank you

Hi,

I have a Crius SE and also a BT adaptor. You have to connect the BT module to the TTL port and not the FTDI port. The standard 4 pin BT plug should attach directly to the TTL socket with black towards the outer edge. I can post a picture if it helps!

Once you have the BT connected to your MW, the red led of the BT module will flash until it is paired with your PC.

Now on your PC you have to bind by pairing. When you search on your PC it should find a Crius and you can choose to pair with a device with an existing code. I did mine on Windows 7. The pairing code is "0000".

Once this is done, if you go to Device Manager in Control Panel you can see which port the BT adaptor is using. This is normally under Bluetooth or Bluetooth devices. Now launch your WinGUI and choose the COM port you noted from Device manager and connect.

All should work.

Hi Hibbo the rctimer blue tooth dongle comes pre configured to 115200 baud and just works,
but some of the other brands are set to 9600 baud and won';t work until you rewrite the configuration to the module, you do this by connecting with a terminal program some thing like AccessPort

Hello.

I';ve tried so many terminal programs and tutorials and still no joy.  Think I';ll just send it back and stick with usb for now.

Cheers tho

Hi Hibbo ive sent you a little program I found that is just for setting up blue tooth dongles, give it a try before you give up 

[hibbo]

Hello, I don';t appear to have received any messages, do you have a link.  I';m intrigued I';ve tried many different programs and none to any avail.

Thanks for that.  This is what happened. 

Port opening success
Checking if module is present
sent AT received
Module not found!

That happened on every baud rate.  The red light on the module was solid, indicating it was connected.

Any clues?  I tried swapping tx/rx cables and restarted the program everytime.

Right then, since loosing my FTDI breakout board I would really like to get my bluetooth module working.  I am thinking I will need to start from scratch.  I';ve searched and searched the internet and it always comes up with the same thing "plug in BT module, click connect, done".  Well this is not the case with mine and I would really appreciate some help, please and thank you.

It is a JY-MCU version 1.05

Is there a way to do it through Arduino?  I can connect the bluetooth module to the GUI and the light goes solid but when I try and read settings in the GUI I get nothing

Thank you
