Python's print statement will automatically call str() on things before it prints them, but Twisted's .write() methods do not. You'll have to change your code to something like this: self.serial.write(str(self.writethis)) Tim. ___ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python

Here is my function (edited)
---START---
def onMessage(self, msg):
#Will just print the msg body to stdout
self.writethis = msg.body
print '>>>\n'
print self.writethis
print '\n>>>\n'
# Send something to serial port
#self.serial.transport.write('some message\n')
self.serial.write(self.writethis)
--
the "print self.writethis" do as told
but the "self.serial.write(self.writethis)" line raise an exceptions
--START-
File "./mytac01.tac", line 44, in onMessage
self.serial.write(self.writethis)
File
"/usr/lib/python2.6/dist-packages/twisted/internet/abstract.py", line
191, in write
self._tempDataLen += len(data)
exceptions.TypeError: object of type 'Element' has no len()

When I first try to adapt your script, there is error complaining about
that "serial" have no "setParent" attribute/methode.
Next I found your enlightment at
http://www.mentby.com/lucas-taylor/serialport-protocol-as-a-service.html
So here is my adaptation at http://pastebin.com/79qi3TfK
currently I just commented the line that send xmpp, I just want to make
sure that the serial communication is working well.
When there ls line comming via serial line, the script just work as told :

The problem is when there is msg coming from XMPP part
It's received by the xmpp client part, but script complaining about
'SerialPort' object has no attribute 'transport'
I tried to send text from another xmppclient (pidgin)
---from the log file
2011-12-23 09:31:29+0700 [XmlStream,client] >>>

2011-12-23 09:31:29+0700 [XmlStream,client] Unhandled Error

And the traceback is---
File "./mytac01.tac", line 42, in onMessage
self.serial.transport.write('some message\n')
exceptions.AttributeError: 'SerialPort' object has no attribute
'transport'
--
Line 42 is
self.serial.transport.write('some message\n')
-
I tried to google with the error msg as keyword ... mostly about Serial
port loosing connection.
In my case , the serial port still have it's connection . since the
arduino msg still coming
