Arduino BT communication Issue

Projects General Guidance
1

Hi,

I am using an Arduino BT V06. A part of my project is to use the Arduino to send data to my smartphone. The Arduino was working fine until I tried to change the baud rate to 9600. I used the following statement to do that.

Serial.println("SET CONTROL BAUD 115200,8n1");

Serial.begin(9600);

From what I understand, the Serial.begin() sets the Atmega UART speed and the SET CONTROL BAUD sets the BlueGiga speed. (This post helped: arduino BT Serial Comms issue - Troubleshooting - Arduino Forum). My problem now is that the Arduino does not respond. I can not program it. Every time I try, it says that the programmer is not responding. Is there any way to fix this without having to solder on to the board? I have no trouble pairing with the Arduino.

Thanks a lot,
Anu A

Sending a string to the serial at some unknown bit rate, and then whilst that string is being shifted out, reprogramming the bit rate is likely to cause you all kinds of problems at the poor, confused receiver.

Not sure how this is an "Installation" problem

I think the reason it's here is that they say they can't program the Arduino anymore.

Disconnect the bluetooth device from the board while programming the Arduino, if you're not doing so already - you generally can't have things connected to pins 0 and 1 while programming it (there are exceptions, but you should assume you can't unless you have reason to belive otherwise.)
