Send message at defined interval.
Takes a PMT message and sends it out every milliseconds. Useful for testing/debugging the message system.
The PMT to send seems to be settable also from the input port (please confirm that)
- Message PMT (R)
- The message to send as a PMT. For example, the following message creates a payload of a simple vector of 16 bytes that contains all 1's.
pmt.cons(pmt.PMT_NIL, pmt.make_u8vector(16, 0xFF))
- Period (ms) (R)
- The specified time interval after which data is sent at the output repeatedly.
In this example, a Message Strobe block sends the string "Demo" once per second.
In another example, we change the frequency of a signal source to 1kHz after 5 seconds.
The message strobe settings in the above example are as follows:
Another example that uses a Message Strobe block can be found in gr-blocks/examples/msg_passing.
