sonnyyu: Did you like try this?
... recvmsg=sock.recv(1024) #print recvmsg sock.close()
I have just modified the Python code to include recvmsg=sock.recv(1024)
and I still do not get a reply sent across to the Arduino side of the bridge. What does #print recvmsg do?
uncomment "#print recvmsg" for debug code at Yun console.
The code send reply back to Yun:
...
import sys
sys.path.insert(0, '/usr/lib/python2.7/bridge/')
from bridgeclient import BridgeClient as bridgeclient
...
bc = bridgeclient()
bc.put('to_arduino',recvmsg)
...
I'm sorry but I don't understand what the complete Python code should be now.
Please would you post the complete code for me.
Regards, Richard
At Yun:
nano /mnt/sda1/udp.py
#!/usr/bin/python
import socket
UDP_IP = "192.168.0.230" #Uno IP address
UDP_PORT = 8888
MESSAGE = "G"
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.sendto(bytes(MESSAGE), (UDP_IP, UDP_PORT))
recvmsg=sock.recv(1024)
print recvmsg
sock.close()
/mnt/sda1/udp.py
make sure return value from nano.
#!/usr/bin/python
import socket
import sys
sys.path.insert(0, '/usr/lib/python2.7/bridge/')
from bridgeclient import BridgeClient as bridgeclient
UDP_IP = "192.168.0.230" #Uno IP address
UDP_PORT = 8888
MESSAGE = "G"
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.sendto(bytes(MESSAGE), (UDP_IP, UDP_PORT))
recvmsg=sock.recv(1024)
#print recvmsg
sock.close()
bc = bridgeclient()
bc.put('to_arduino',recvmsg)
Thank you once again. I have tried your code that uses the Yun Bridge and it works. I am using it to control my Wi-Fi lights and to retrieve the reply sent by the Uno controlling them.
Without your help I would have given up long ago. I have learnt a lot about the Yun with your help.

Hey, been following this trying to get it to work, and I think I'm very slowly understanding this.
I've got nano /mnt/sda1/udp.py to run, and that's to edit a file on the sd card right? To do that I need to use
export TERM='xterm-color'
To stop the error
Error opening terminal: xterm-256color.
So it opens fine, but when I try and write the next line of code I get [ Error writing /mnt/sda1/udp.py: No such file or directory ]
Have I just done something really silly somewhere?
Thanks! John
vi /etc/profile
export TERM=xterm-colo
exit ssh then relogin

Plan B:
Start from fresh (backup your own file!):
/usr/bin/reset-to-factory-anyway
reboot
If I try
vi /etc/profile
export TERM=xterm-colo
I get
#!b/in/sh
rt TERM=xterm-colo
[ -f /etc/banner ] && cat /etc/banner
export PATH=/bin:/sbin:/usr/bin:/usr/sbin
export HOME=$(grep -e "^${USER:-root}:" /etc/passwd | cut -d ":" -f 6)
export HOME=${HOME:-/root}
export PS1='\u@\h:\w\$ '
[ -x /bin/more ] || alias more=less
[ -x /usr/bin/vim ] && alias vi=vim || alias vim=vi
[ -z "$KSH_VERSION" -o \! -s /etc/mkshrc ] || . /etc/mkshrc
[ -x /usr/bin/arp ] || arp() { cat /proc/net/arp; }
[ -x /usr/bin/ldd ] || ldd() { LD_TRACE_LOADED_OBJECTS=1 $*; }

I /etc/profile [Modified] 2/16 12%
and every time i enter it increases both sides by 1, 3/17 etc And I'm still getting the error no file or directory. Thanks!
Plan B: ...
That was after trying plan b.
Post
uname -a
vi /etc/profile
modify file:
...
export PS1='\u@\h:\w\$ '
export TERM=xterm-colo
...
On it now! Thank you so much for taking the time to help me!
Okay, so nothing to reset is coming up on the arduino.local page. I used my computer to put the file on the SD card. The SD card is called SD and I put the file in the root folder
EDIT: Tried using terminal too, same message as before, no such file or directory

PC is no needed for helping create file or directory at linino.
Next issue ,followed the steps in that link, I can't see the sd coming up with fdisk -l. Just keep asking if I specified it correctly.
Looking at this link I think it may be faluty.

Going to try this all with a flash drive... I read they mount in similar ways, so thinking that should work the same?
Tried with the USB flash drive and I can now write the lines of code! (success) but when I try and run it I now get permission denied! (aww)
Any ideas?
chmod 755 run.py
Awesome, I can receive the G over on another laptop running Max, woo. Now I'm trying to send 4 analogue pins over it (and ideally a couple of digital things, but not essential at the moment). Looking into bridge etc, but I can't work out how to get it from the arduino sketch into the python sketch (then onto Max). I'm guessing that I'll need to change MESSAGE into something? Again, thankyou!
