If the taps need to be changed exactly at the tag, then I think you'll have to make your own version of the filter block you're using, adding handling for a "set_taps" tag. None of the filter blocks pay any attention to tags and a call to set_taps() would take effect "approximately" when you mean it to.

If the taps need to change at approximately the time of the tag, then you could just either (1) forget about tags and drive the changes from your Python program, or (2) make a block (e.g., Python Embedded) that just looks for tags in the stream and calls set_taps() on your filter.

Hi, I am looking for comments/thoughts/advice on how to combine (fan in) untagged and tagged streams.

Basically my goal is to make a sample synchronous filter with adjustable taps, where the data to be filtered is a untagged stream that periodically has a tag flag saying "update taps" when this flag is seen the block will look at the other input (tagged) and use the next pdu block there as the taps for the newly configured filter. I do not want to define the filter length before runtime, and that as the number of filter taps can change between update calls. Also because there is no packet type structure It does not make sense for the data stream to be tagged (though that is my current fallback plan).
