Being too slow seems unlikely to produce the wrong data... def OnSerialRead(self, event): > text = event.data > self.sensorabuffer = self.sensorabuffer + text > self.sensorbbuffer = self.sensorbbuffer + text > self.sensorcbuffer = self.sensorcbuffer + text > > if sensoraenable: > sensorresult = re.search(r'\$A.*\$.*', self.sensorabuffer ) > Here, you search in sensorabuffer (which, by the way, would be much more readable to me as sensor_a_buffer, as recommended by the PEP 8 style guide). > if sensorbenable: > sensorresult = re.search(r'\$A.*\$.*', self.sensorbenable) > here, you're not searching in the buffer, but in the enable flag. > if sensorcenable: > sensorresult = re.search(r'\$A.*\$.*', self.sensorcenable) > And here too.
