Dylos RPi Serial problem
2014-10-07
####DYLOS RPi serial Problem#### 1. RPi(Raspberry pi) has a problem in the serial read of dylos air quality monitor data. The serial read ends with wrong or misplaced data from the dylos monitor, this problem is mentioned in this (note)(Serialportproblemlbm1knmr.md). For example, running of the python command for getting dylos serial read ends as follows
pi@raspberrypi ~/SMS $ python
>>> import serial
>>> ser = serial.Serial('/dev/dylos', 9600, timeout=60)
>>> line = ser.readline()
>>> line
'376499,3\n'
the read line data is wrong as of dylos reading.
As a proof, the dylos monitor with same setup, same SERAL TO USB connector was connected with BBB(Beagle Bone balck) usb port and run the sampler script. it ends as follows
root@arm:/home/debian/aerocet# time python sampler.py 2014-10-07T12:46:47,3185,65 real 1m0.474s user 0m0.311s sys 0m0.088s
