gr-pdu: Upstreaming PDU Blocks
summary
GNU Radio 3.10 adds gr-pdu with concrete PDU processing blocks, type checks, standardized metadata keys and a pdu lambda block that runs arbitrary functions on PDUs. The motivation is explicit: receive bursty modem packets and transmit different packets at a chosen time/frequency, which is simpler as a single PDU than with streaming workarounds. Tradeoffs are measured: some throughput loss, infinite queue risk. Working examples and a GitHub demo (baby monitor receive) exist and do work.
