Stability improvment bluetooth startup: The previous implementation expected a default setup of the Bluetooth module. Deviations from the default expectation caused the init function to stop. The new implementation is able to fix wrong baud rate setting (reset baudrate to default 115200). In addition the function evaluating the answers of the module is not able to derive the status out of a data stream.
