Baudrate doesn't have much meaning for it. Only the real UART interface between HC-05 and Arduino really needs a baudrate | |

Any baud rate higher than this did not work for neither HC05 - HC05 nor HC05 - Android. Also, I could not find a way in the Bluetooth Documentation (developer.android.com/reference/android/bluetooth/…) to change the baud rate used on the Android device with Bluetooth SPP. It was as if the device automatically adjusted to the baud rates I configured on the HC05. i.e. 9600 - 115200. | |
