Python Pyserial Windows No Port Found -


i have tried connect usb mobile send sms through using @ commands. when use pyserial connect in windows os, error not open port, file specified cannot found.

>>> import serial >>> ser = serial.serial(0)  # open first serial port >>> print ser.name          # check port used >>> ser.write("hello")      # write string >>> ser.close()

even if replace 0 other value, 0 -10 or 'com0','com1' etc, still error file specified not found, port cannot open.

there command listed in pyserial documentation lists ports or allows open port

python -m serial.tools.miniterm

this command supposed list serial ports. shows none.

i have 3 usb ports on system. causing issue.

pyserial not guaranteed detect ports. depends on how device , os communicate , if pyserial designed pick on this. example, pyserial not detect labjack u3-lv or epsom-pos receipt printer plugged in in win8 session (both detected using linux session).

try serial.tools.list_ports.comports() , see gives you.

you @ pyusb module usb connections.

also: recommend being careful when using numbers ports, mapping may not "common-sense" logical (i.e. 0 may not map com0). use explicit string names instead.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
