user20317: Iam working with gyroscope and Iam trying to send its values from one bluetooth(HC-05) module to another bluetooth module but the data exchange is not happening and I have used 2 arduino boards to do it.
Is there a simple way to do it? 

user20330: I think there is no simple answer for that. First you have to pair 2 HC-05 modules. To do so, you have to configure one HC-05 as slave, and other HC-05 as master.
Steps for SLAVE:

Be sure to select correct Baudrate in your Terminal Emulator (Arduino IDE or Terraterm etc.) for your module. There is no default baudrate... Different manufacturers set the baudrate on their HC-05's differently... 9600 and 38400 are good starting points.
Enter AT mode, by providing high level(3.3V or 5V) signal on KEY pin(PIO11)
Note the values of AT+PSWD?, AT+NAME? and AT+ADDR?(let's say 1111:22:123456) commands. You might set the password to 1234 for easy remembering. Issue AT+PSWD=0000...
Be sure to set the module to slave mode by issuing AT+ROLE=0 command.

Steps for MASTER:

Be sure to select correct Baudrate in your Terminal Emulator (Arduino IDE or Terraterm etc.) for your module. There is no default baudrate... Different manufacturers set the baudrate on their HC-05's differently... 9600 and 38400 are good starting points.
Enter AT mode, by providing high level(3.3V or 5V) signal on KEY pin(PIO11)
Reset the module to its original state by issuing AT+ORGL command.
Remove the previous parings(if any) by issuing AT+RMAAD command.
Set same password as slave by issuing AT+PASSWD=0000 command.
Change the role to master; AT+ROLE=1
Set connecting mode to any address it sees; AT+CMODE=1
Initialize the SPP profile lib ; AT+INIT
Be sure that you see the slave HC-05 module, AT+INQ command will list the modules you see.
Be sure that you see address of the slave module(1111:22:123456).
Last of all enter AT+LINK=1111,22,123456(note the commas).

With these steps you should exchange data...
