PcapPro pcap = null;
pcap = PcapPro.create(device);
BpFilter filter = pcap.compile(filterStr, true); // this line error

i see Pcap can add filter, is that PcapPro doesn't support?
this is the example code:
/* Automatically close Pcap resource when done */
try (Pcap pcap = Pcap.openOffline(PCAP_FILE)) {

		/* Compile packet filter to capture TCP packets only */
		BpFilter filter = pcap.compile("tcp", true);

		/* Set our packet filter and start the capture */
		pcap.setFilter(filter);

		/* Number of packets to capture */
		final int PACKET_COUNT = 10;

		/* Send packets to handler. The generic user parameter can be of any type. */
		pcap.dispatch(PACKET_COUNT, this::nextPacket, "Example 3");
	}

change to Pcap is the same.

Pcap pcap = Pcap.create(device);

[cq1982]

PcapPro.openOffline supports setFilter();

PcapPro.create doesn't support setFilter()

Are you running the example exactly as is or opening up a live interface with Pcap.create? If live capture you need to call Pcap.activate() before the filter is set.

When I run the example on offline file:

Example 3: timestamp=2011-03-01T20:45:13.266Z, wirelen=74   caplen=74   {00:26:62:2f:47:87}

Lets see if I can duplicate the problem you are seeing.

this is also fine...
pcap = PcapPro.openLive(device, snapLen, true, 100, TimeUnit.MINUTES);

thanks.
