Upon running the modified flowgraph (and tuning to an RDS-capable FM station), RFtap packets should start flowing to localhost interface (127.0.0.1). We will use the “Custom Dissector” option, and specify the dissector name as rds (Wireshark dissector names are typically all-lowercase). This can be specified in the RFtap block itself (option: Custom Dissector), or as part the incoming PDU metadata, as “dissector” field. For example, Wi-Fi packets would have a DLT of 105.Īlternatively, if the packet type isn’t listed in the DLT list, you can specify a Wireshark dissector name to be used for dissecting the packets. If the packet is of one of the standard types appearing in the Data Link Type (DLT) list, you can just specify the DLT value in the RFtap block itself, or in the PDU metadata as “dlt” field. In order to be able to correctly interpret the (RDS) data packets, Wireshark needs to know the type of packet (Wi-Fi, Bluetooth, RDS, etc). Sidenote: Data Link Type (DLT) or Dissector Name?
