UDP port 5554 #4

Closed woobagooba closed 9 years ago

woobagooba commented 9 years ago

Can't get any data from this port.

Using the simulated 0183 input from file and nast to monitor ports 5554-5557...

  1. TCP 5557 is streaming 0183
  2. UDP 5556 streams 0183, but only after pressing the return key
  3. TCP 5555 does stream the heartbeat and is further able to accept a subscription.
  4. UDP 5554. Unable to get anything from it.

typo nast -> ncat

The UDP implementation is Netty, using nio. So far Ive only managed to be able to recognise that a UDP client has attached after it sends some data - hence your [CR] triggers it. Any-one with experience of Netty UDP?

Port 5554 also requires input which would normally be the subscription. I need to do some more work on it it seems. Bit short of time at present so it may not be soon.

Port 5554 now works after a [CR] is sent after connection. It replies with the expected heartbeat. Sending a subscription message returns the expected results. Closing this and opening a [CR] related bug
