DevBugfix CO2 sensor in streaming mode: In standalone mode (no multiplexer) the CO2 sensor is working in streaming mode => it could happen that the OSTC received data before the scaling factor was requested. As result the CO2 values were calculated with a zero value. This problem has been fixed. In addition some code cleanup has been done. Unifying usage of changeBaudrate function instead of old baud selection based on protocol request of Discovery firmware.
