PScan | A simple port scanner with multi-IP support | TCP library

I'm creating a program that can do two things, it will calculate a range of odd number IP addresses or scan an IP address for open ports.

I have having issues with the code on lines 58 to 73. The issue is the end user must input thier choice twice before the program registers the choice, i only want the end user to input their choice once

for example:

1. the program asks the user if they wish to calculate a network IP address, or scan ports.
2. the user enters their choice

3. the program, then asks AGAIN for the user to enter their choice #this is this issue

4.the user enters their choice AGAIN

1. the program runs.

I want the program to only ask the user to enter their choice once, then run the program.

full code, issues on lines 58-73

I am trying to export a string output to notepad on lines 19 and 20.

Code section, lines 1-21

I am attempting to set up a while loop with this script. The Script will ask the end user to input a choice. The Script will then run a function based on the end user input.

I have created an if/elif/else statement in lines 43-48. As you can see, on line 47-48 if the end user enters the incorrect command, the shell will print "incorrect input"

When the user enters the incorrect input the script ends, I wish for the script to instead reask the question on line 45.

I want to run this command:
././pscan `cat ips` 22
but the script don't run corectly

I have an embedded Bluetooth 4.0 module (A Laird BT900 with uses a CSR 8811). I am trying to debug some issues that occur during discovery and connection with other devices. So I am trying to understand exactly what this device is communicating about its capabilities to others during an inquiry.

On my embedded module if I disable pairing, and then run hcitool info I see the following
