Bluetooth Arduino question !

Hello Arduino guys!

This is the first time ever, that i am entering an arduino forum and there are so many options around here, i am not even sure that i am posting my question in the right place - if i am not, can you please explain or send me links or keywords for the correct pages? Thanks a lot!

Here is my question:

I am trying to build a robot, that uses the "Bluecontrol" android application.

Here is the Bluecontrol app on google play:

The robot, called "MegaPed", building instructions and arduino sketch are detailed on www.instructables.com, on this page:

I have done everything exactly according to written and drawn instructions on that page, with only one change:

I have switched this BlueSMiRF bluetooth module, which is quite expensive:

With this JY-MCU Arduino Bluetooth Wireless Serial Port Module:

Now, my problem is, that after uploading the sketch - My android smartphone, is trying to connect with the bluetooth module, but shows that the module (called "linvor" on the smartphone screen) is: "Paired but not connected" - And i am unable to proceed and control the robot from the Bluecontrol application.

Maybe you can help me solve this problem or refer me to someone who might help me to solve this problem?

Thanks a lot,
Roi Neustadt.

Well, posting the same question five times in different parts of the forum is unlikely to endear you to other users.

Why didn't you read the thread that says "How to use this forum - please read"?
It is at the top of every section of the forum, with a header in bold to make it stand out.

I would imagine you would have to modify the sketch to account for the different bluetooth controller. Each different bluetooth controller has different ways to program it. I happen to have two bluetooth controllers, a HC-05 controller and the bluetooth shield from seeed, and their AT commands, name, etc. are different.

You also didn't mention how you connected the bluetooth controller to your Arduino.

I would suggest before trying to get a robot to work, you concentrate on just getting the connection between the phone and the Arduino. Write a simple program that when you get an 'a' from the bluetooth module, you turn on LED 13, and when you get an 'A' you turn it off. That way you will know that you have the connections setup. You should make sure the connection goes both ways, so that writing from the Arduino goes to the phone. After you have that setup, then you can tackle the robot.
