Hi all,
I am using Intel Edison Breakout Board. I am getting data from photodetectors and my aim is displaying these signals as a graph. I can do it on my computer via serial port, however; I want to do it wirelessly.
I programmed Edison with Python and MRAA library to receive the data and plot but since breakout board does not have any display, it cannot show the graph. Can I see the graph on my computer without using serial communication?
Here is the code that I use:
# !/usr/bin/env python
import mraa
import time
import sys
import urllib
import re
import matplotlib.pyplot as plt
import matplotlib.animation as animation
plt.ion()
fig = plt.figure()
ax = fig.add_subplot(111)
data = []
led = mraa.Gpio(13)
led.dir(mraa.DIR_OUT)
det = mraa.Aio(0)
while True:
led.write(1)
time.sleep(2)
value = int(det.read())
print value
led.write(0)
time.sleep(0.5)
value = int(det.read())
print value
data.append(value)
secPlot = ax.plot(data)
fig.canvas.draw()
What should I add it to send the graph to computer wirelessly?

Hi GCay,
In order to do this, you will need to store the data from the photodetectors and then use some kind Wireless communication protocol in order to transfer this data to the computer and then graph it. One protocol that may be useful is the P2P connection this documentation might be of interested to you:

I could not try it yet because of internet connection problem. I will try it and let you know.
I have another question actually. Does Edison Breakout Board have MAC address? If so, how can I find it?

Hi GCay,
Is there a reason why you need the Edison MAC address? If you are looking just to pair up the Edison with another device you can use the BlueZ commands in order to achieve this.

We will be waiting for your reply, have a nice day!

I installed nmap 7.50 both Edison and my computer. it has ncat inside it.
I am using it in Edison as connect mode by typing ncat and it connects properly.
But in Windows, I am trying to connect it as listen mode by typing ncat --listen . It gives this error.
"The requested address is not valid in its context. . QUITTING."
I scanned Edison's IP address by nmap and it returns without any problem.
So do you have any idea about the reason of getting this error?
I am using Windows 10.

Hi GCay,
Personally, I don't have too much experience with Nmap, I would encourage you to post your questions on this community http://seclists.org/nmap-dev/ Nmap Development Mailing List . They might be able to help you further with your inquiries.

Ok, I sent them an email.
Also I am trying to install Virtual Machine on my computer with Ubuntu. I'll let you know about the results.

I was able to establish TCP/IP connection between Edison and computer. It is sending string successfully now.
The problem is that I cannot send integer value.
Here is my code:
TCP Server
import socket
import mraa
import time
# file = open("data2.txt","w")
host = '172.30.212.118'
port = 22
x = mraa.Gpio(20)
x.dir(mraa.DIR_OUT)
s = socket.socket()
s.bind((host, port))
s.listen(1)
c, addr = s.accept()
print "Connection from: " + str(addr)
while True:
for i in range(0,20):
x.write(1)
data = int(x.read())
if not data:
break
print "sending: " + str(data)
c.send(data)
for i in range(0,5):
x.write(0)
data = int(x.read())
if not data:
break
print "sending: " + str(data)
c.send(data)
s.close()
TCP Client
import socket
import urllib
import sys
import re # for regular expressions
from time import sleep
from collections import deque
import matplotlib.pyplot as plt
import matplotlib.animation as animation
# import serial
plt.ion()
# Turn on interactive plotting
fig = plt.figure() # handle to figure
ax = fig.add_subplot(111) # handle to axis
data = []
host = '172.30.212.118'
port = 5000
s = socket.socket()
s.connect((host,port))
while True:
data = s.recv(1024)
print 'Received from server: ' + str(data)
# secPlot = ax.plot(data, 'b-')
# fig.canvas.draw()
s.close()
It should send 1 and 0. It establishes the connection, turn on the LED, get the value '1' and print it to screen but then I am getting this error:
Connection from: ('172.20.34.172', 9037)
sending: 1
Traceback (most recent call last):
File "tcpServer.py", line 27, in
c.send(data)
TypeError: must be string or buffer, not int
How can I send 1 and 0? Or float value because in further, I need to send analog values like 0.1, 0.3 etc.
Thanks.

Hi GCay,
Personally, I don't have too much experience with TCP/IP. I looked for the error "TypeError: must be string or buffer, not int" and in most cases this was because libraries that you are using only accepts a string. My advice would be to create a decoder, so that when a string arrives, it will be able to give the correct analog value.
Hope this helps, have a nice day!
