Re: [Discuss-gnuradio] Timer

[Roee Bar]

Thanks Nathan, that was a great advice.

Since I use python, it's very easy when using the 'threading' module:

def start_timer(self):
  self.timer = threading.Timer(seconds, self.callback)  # Setup a Timer thread
  self.timer.start()

def callback():
  # Do something if timeout

def msg_handler(self, msg):
  self.timers.cancel()  # Cancel timer if msg arrived before timeout

Spin off a thread inside your block that counts and calls the appropriate function. Boost bind might help abstract away a specific function.

Hello,

I have written a OOT module (in python) that receives and send PMT messages according to some state machine.

However, I need a timer so that the block will transmit a message after some timeout. I.e., if nothing happens for x seconds, a function is called.

Is there any built-in mechanism in gnuradio for this?
If not - I thought I should implement another block that act as a timer (i.e., it receives a message "wait x seconds" so it goes to sleep for x seconds and sends a message back when it wakes up). But there must by an easier way than this.

Thanks in advance,
Roee
