It works, I just used a small test file so the ncurses went too fast -
poc was just print - this works with ncurses too!

#!/usr/bin/env python

stdscr = curses.initscr()
# I realize this is an infinite loop
# parse the CSV file
for line in open('foo-01.csv'):
# look for the line with the right MAC
index=line.find(':5a:84')
while index != -1:
start = index + 1
index = line.find(':5a:84', start)

# send the line to the screen
# print line
stdscr.addstr(0, 0, line)

sleep(2)

# redraw the screen
stdscr.refresh()

sleep added so I could see results.

That did not work for me. I did not see any results on the screen and it just went back to the command prompt. Also, sleeping for two seconds would be too much as I need to see the fluctuation of signal strength in real time as much as possible.

On the other hand, Edmond's suggestion of adding ":" to the if line in my original script did work. Thanks! An oversight on my part. There is still and unacceptable latency in the results. Any thoughts on how to speed it up? Here is the working code:

#!/usr/bin/env python

import curses
# create curses screen using whole display
stdscr = curses.initscr()
# I realize this is an infinite loop
while True:
# parse the CSV file
for line in open('foo-01.csv'):
    # look for the line with the right MAC
    if line.find(':5A:84') != -1:
      # send the line to the screen
      stdscr.addstr(0, 0, line)
      # redraw the screen
      stdscr.refresh()
# I realize I am not properly cleaning up, but will get to that later
