Another newbee question about Serial.Read
Posted: Mon Dec 27, 2010 12:13 pm
I thought it was simpel but i'm getting frustrated now...
I want to read an analog value from a domotica controller called 'Nodo'. After sending 'Status WiredAnalog 1;' to the serial port, the domotica controller immidiately responds with 'WiredAnalog 1, 31)' terminated with 0x10. I want to catch this string so I can extract the value 31, but my Python script does not catch the string properly.
This is (a part of) my pyton script:
My scripts only returns only parts of the returned serial string of hash. I'm sure the serial connection is Ok.
Can anybody help?

Serial = eg.plugins.Serial
print 'Get the analog value...'
Serial.Write(u'Status WiredAnalog 1;')
ReceivedString = ""
b=0
# receive all input until \n
while b != "\n":
b=Serial.Read(1, 0.1)
if b != "":
ReceivedString += b
print "Return value: " + ReceivedString
