Maybe you can check the TA logic in here/ https://github.com/frankie-zeng/ECUBus/blob/master/src/uds/ipuds.js

@ryanbaw Hi, I have setuped the doip server you used, If you doesn't change the server code, the server will show: NACK 03.
I change the build/install/doip-custom-simulation/EMS.properties physical address from 0x1001 to 0x1000. It can work.
