Changing DF-bluetooth v3 module name with AT mode
MakoShark2 2013-01-22 02:59:27 3913 Views2 Replies Hi.
I have a bluetooth module (v3) hooked on a Romeo v1.1 board, and everything works fine.
Now, I'm trying to change the name broadcasted by the module (by default "Bluetooth_v3") to something else.
I've set AT mode to ON, on the board and send the adequate command to serial port:
Serial.print("AT+INIT\r\n");
Serial.print("AT+NAME=MyBT\r\n");
Serial.print("AT+STATE?\r\n");
Problem is, I should get some response, but listening to the serial port returns nothing.
Any one there that have successfully configured this device with AT commands?
Thanks.
Cheers.

Today I found that DFRobot had updated the wiki of Bluetooth Module V3 and I think you may take a reference to the wiki.

I have met the same problem several days ago and I think if you turn the AT mode on, the Bluetooth module cannot communicate with Arduino via the serial port.
If you want to change the settings of the Bluetooth module, you may try this method.
Firstly, you can download a "CoolTerm" software (CoolTerm is a simple serial port terminal application) to send the AT commands and see what kind of information the Bluetooth will answer to you.
Secondly, maybe you need something like the "USB to Serial Converter" to make the Bluetooth module talk to the computer. I just put my Bluetooth module on a "USB to Serial Converter" and connect the converter directly to my computer.
Finally, open the CoolTerm software and set some parameters. In the menu bar, you can see one option called " Connection", click Connection and you will see its sub-menu. In the sub-menu, please choose "Options".
<1> Choose the "[b]Serial Port[/b]" item and you can set the port number\Buadrate\Data Bits\Parity\Stop Bits there.
1)You can obtain the port number from the"Device Manager" in your computer;
2)You can set the buadrate like 9600/38400,etc. But each time you change the baudrate, please re-power the Bluetooth module. ;)
3)The "Data Bits" option can be set as 8 and "Stop Bits" as 1.
4)I set the "Parity" option as "none".
5)You do not need to set the "Flow Control".
<2>Choose the "[b]Terminal[/b]" item and set the "Terminal Mode" as "Line Mode". This setting can display what you have input.
After all of these configurations, you can easily use the AT mode to set the Bluetooth module. For example, if you input [i][b]at[/b][/i], you can see the Bluetooth answers you " OK" in the display window; if you input [i][b]at+name=Tommy[/b][/i], you will get another "OK" and then if you input the command [i][b]at+name?[/b][/i], the Bluetooth will tell you its name is "Tommy".
Please have a try. :D leletkt
