Assuming you're not getting an exception thrown, that doesn't look like a complete packet. You need to include every layer (including the Ethernet frame for example) and not just a TCP/UDP payload since the buffer
you're sending here is what will be literally transmitted by the network card.

Great! Thank you for the quick reply. Cap is great. I cannot believe the capture part just work without any problem.
So the send part. Seems the filter does nothing. I thought set filter to TCP means you can send TCP packet. So what filter I should set for sending?
from cap.
The filter is only for the traffic you want to capture. send()
literally just sends the provided data over the network card and is not affected by anything else.

I just tested, in Wireshark, I captured a packet sent from an app from my machine to a remote server. The packet size is 81, so I copied the Hex stream, and send it out. But I did't capture it in Wireshark. Any idea? Thanks!
var buffer = Buffer.from("a84e3f6c6642281878fe6aeb08004500004319c4400080060000c0a801a1ca27f132eb5b4e235bbc04e725b9a329501802007dd900008295872d0c178e280e10872d0c17872d0c1ea9370d17841c3e2487");

Same issue, The library can not do any .send() with any data, as example here is my full packet :
var buffer = Buffer.from("01005E0000FB0A0027000011080045000051CB700000FF111686C0A83801E00000FB14E914E9003D119F000000000001000000000000095F7733787032373266045F737562095F626C697A7A617264045F756470056C6F63616C00000C0001");
