Hi,
I am trying to read the data from serial port using python 2.5 with 
ceserial module on windows CE 5.0. When i am trying to run, it is get 
connected to port, but it is not reading the data from the port.Below is 
my code -

from time import sleep
import ceserial

ser = 
ceserial.Serial(port="COM1:",baudrate=9600,bytesize=8,stopbits=ceserial.
STOPBITS_ONE,parity=ceserial.PARITY_EVEN)

print("connected to: " + ser.portstr)

#data = ''
while True:
    data = ser.read(9999)
    if len(data) > 0:
        print 'Got:', data
    sleep(0.5)
    #print 'not blocked'

ser.close()

Hi,

I have also downloaded ceSerial and successfully communicate with serial 
ports. I have successfully write the data to the port but I am not able 
to read the data from the ports. It is getting connected to the port but 
it is not able to read the values. Below is my code snippet for reading 
the data from the port.

Can you help me to solve this issue.

from time import sleep
import ceserial

ser = 
ceserial.Serial(port="COM1:",baudrate=9600,bytesize=8,stopbits=ceserial.
STOPBITS_ONE,parity=ceserial.PARITY_EVEN)

print("connected to: " + ser.portstr)

#data = ''
while True:
    data = ser.read(9999)
    if len(data) > 0:
        print 'Got:', data
    sleep(0.5)
    #print 'not blocked'

ser.close()

Regards
Rushali

Hi,

You seem to be missing the essential steps of ser.open() before trying
to read and ser.close() at the end.

Hello Sir,

I have open the port as ser.open() before trying to read but it is 
giving me output as connected to COM1:
Got:
But not going to read the data. I am sending you my updated code. Please 
have a look on it.

from time import sleep
import ceserial

ser = 
ceserial.Serial(port="COM1:",baudrate=9600,bytesize=8,stopbits=ceserial.
STOPBITS_ONE,parity=ceserial.PARITY_EVEN)
print("connected to: " + ser.portstr)
ser.open()
#data = ''
while True:
    n = ser.inWaiting()
    size = n
    data = ser.readline(size)
    if len(data) > 0:
    print 'Got:', data
    sleep(0.5)
    #print 'not blocked'
ser.close()

Regards
Rushali

Hi

I have open the port before trying to read the data but it shows only 
output as-
connected to:COM1 
Got:
It is get connected to the serial port but not able to read the values 
from the port. I am sending you the my updated code snippet. please tell 
me the solution for it.

from time import sleep
import ceserial

ser = 
ceserial.Serial(port="COM5:",baudrate=9600,bytesize=8,stopbits=ceserial.
STOPBITS_ONE,parity=ceserial.PARITY_EVEN)

print("connected to: " + ser.portstr)
ser.open()
#data = ''
while True:
    n = ser.inWaiting()
    size = n
    data = ser.readline(size)
    if len(data) > 0:
     print 'Got:', data
     sleep(0.5)
    #print 'not blocked'
ser.close()

Hello,

I thought I would send a short comment, as I have used the ceserial module
(a long time ago) for my HP iPaq running PythonCE 2.5. I recall that the
ceserial module tries to implement what the standard serial module does for
Python, but depending on the actual version of ceserial used there may be
some small differences in the naming of the of the properties and
variables. It is worth verifying in the ceserial module that it is actually
settings the parameters as expected for the serial port object.

That aside, I would also say that a PARITY_EVEN setting would be unusual
these days and that PARITY_NONE is more common. I think I also found that
the stopbits setting did not set the port as expected. Sorry to not have a
definite answer, but an oscilloscope will show you what the device is
trying to do. Finally, perhaps the device you are connecting to is
expecting the DTR line to change?

Hello,

Just to add to my previous message, the ceserial module uses ctypes to
access the same functionality which would be used by a WinCE application
written in VB or C#. I have just checked and Microsoft appear to still have
the reference pages available, so you may find that the following link can
guide you in checking the serial communications:

https://msdn.microsoft.com/en-us/library/aa450503.aspx

(I am assuming WinCE version 5.0, but I think WinCE 6.0 and later versions
will also be available)

For checking your device is communicating as expected, you could try to use
a third party terminal program that can also access the serial port. I
recall using vxHpc and also PocketPuTTY. These can be installed directly
onto the WinCE device and allow you to test the serial port. Then you can
try connecting the WinCE device directly to a computer to check
communication settings are correct, then connect your serial device
directly to a computer (just the regular troubleshooting steps really).

Good luck

AdamW
