Android Bluetooth Serial Baud Rate
The BT module is set at 9600 baud rate. On the Amarino site is written: IMPORTANT!!! Please set your Bluetooth module to 57600 baud (using Putty or other Terminal programs) otherwise you will get corrupted data. Arduino/Android BLUETOOTH Serial Monitor APP for Arduino Using the HC-06 and ANDROID: Hello world! Today i made a Android app that simply reads values or text that are printed to the arduino serial using the bluetooth module HC-06/05 or any other modules. You don't need to set anything in the arduino code. Just simply Serial.printl. Bluetooth Bee default mode is AT module, the baud rate of which is 38400. If you want to get AT module, you should set work mode. After power on then input the Bluetooth Bee's pin20 to high level, then the module will enter to AT module. At this time, the baud rate is 38400. You can get the AT command from here. About the tool to choose the serial port, SecureCRT is a nice choice.
I'm new to Android and im developping an application to talk with an Actuator via Bluetooth.When trying divers Codes i faced a problem with the Baudrate as the Actuator Bluetooth BaudRate is 19200 while the Android Tablet is 9600.Can anyone tell how to change the Baudrate in my Application.By the way i downloaded an Application from the Play Store named BlueTooth SPP and i tried to communicate and send packets throw it and it Worked.I really need to know the Secret behind it.Thanks

Android does not set the baudrate, the default rate is set by the Actuator. You may need to find a way to set this on the actuator. I had a similar problem on the HC-06 where I changed the baud rate in my code (from 9600 to 115200), but this did not change the default baud rate, which meant android would only read the device at 9600.

I changed the default baud rate using the instructions here:

and also here:
Finally, if you are using an arduino and you do not have a USB-FTDI, you can use this page:
