Message Strobe

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)

Parameters
(R): Run-time adjustable


 * 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.

Example 1
In this example, a Message Strobe block sends the string "Demo" once per second.



Example 2
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:



Example 3
Another example that uses a Message Strobe block can be found in gr-blocks/examples/msg_passing.
