- PySerial is a library which provides support for serial connections ('RS-232') over a variety of different devices: old-style serial ports, Bluetooth dongles, infra-red ports, and so on. It also supports remote serial ports via RFC 2217 (since V2.5). Projects using PySerial. BitPim - crossplatform application to view and manipulate data on CDMA phones from LG, Samsung, Sanyo.
- How can we query connected USB devices info in Python? I want to get UID Device Name (ex: SonyEricsson W660), path to device (ex: /dev/ttyACM0) And also what would be the best Parameter out of above.
Can someone please show me a full python sample code that uses pyserial, i have the package and am wondering how to send the AT commands and read them back!

I have not used pyserial but based on the API documentation at https://pyserial.readthedocs.io/en/latest/shortintro.html it seems like a very nice interface. It might be worth double-checking the specification for AT commands of the device/radio/whatever you are dealing with.
Specifically, some require some period of silence before and/or after the AT command for it to enter into command mode. I have encountered some which do not like reads of the response without some delay first.

Python Serial Port Example
Next in Idle create a new window and create the below program.
Two things to keep in mind. To determine what serial port your Arduino is connected to look at the bottom right corner of your Arduino sketch. Whatever that is should be what is in quotes in line 3 of the Python program.
You can also change the baud rate in line 3 of the Python program and line 2 of the Arduino program as long as they stay the same.
Once you run the program it will print out the majority of ASCII characters. By first sending them to the Arduino, which will in turn send it back to the computer that Python then prints out.
from time import sleep
import serial
ser = serial.Serial('/dev/tty.usbmodem1d11', 9600) # Establish the connection on a specific port
counter = 32 # Below 32 everything in ASCII is gibberish
while True:
counter +=1
ser.write(str(chr(counter))) # Convert the decimal number to ASCII then send it to the Arduino
print ser.readline() # Read the newest output from the Arduino
sleep(.1) # Delay for one tenth of a second
if counter 255:
counter = 32
