Bridge communication - part1

Some first trials with the Arduino Bridge. Starting simple with put and gets.
A first trial:

• the Linino puts random characters using key1  (then waits 3 seconds)
• the Sketch side gets on key1, and puts the same message on key2 (should happen in the 3 seconds)
• the Linino gets on key2 and compares with what it had put on key1. If OK, it restarts with a longer message. If it fails it tries another get.

At a message length of 266 (always that length) it seems to FAIL:

From that length onwards, I keep on receiving the previous message...did the Arduino side crash??
If I reset the Arduino side, things are ok again.

This is the python script:

def id_generator(size=6, chars=string.ascii_uppercase + string.digits):
    return ''.join(random.choice(chars) for x in range(size))

sys.path.insert(0, '/usr/lib/python2.7/bridge/')
from bridgeclient import BridgeClient as bridgeclient
bc = bridgeclient()                          

for x in range(250,300):
 myrand = id_generator(x)
 print "Trying length",x
 print "put", myrand
 bc.put('to_slave',myrand)
 # wait for identical returned message
 while True:
     time.sleep(3)
     r = bc.get('from_slave')
     if r is None:
        print "No answer key found yet"
     else:
        print "got", r
        if r==myrand:
            print "OK"
            break
        else:
            print "FAIL"

This is the sketch:

#include <Bridge.h>

char value[512];

void setup() {
  pinMode(12,OUTPUT);
  Bridge.begin();
}

void loop() {
  Bridge.get("to_slave",value,512);
  Bridge.put("from_slave",value);
  delay(100);  
}
