i have effect here drives me crazy. got windows 10 pc system in local network @ home ( typical 192.168.178.x network fritzbox dns , gateway) runs fine. windows pc can connect internet, can browse, play games in internet etc. playing around little device (esp8266 , oled) connected via wlan fritzbox, while windows pc via cable. device shall receive udp messages (no broadcast, direct) , display them on oled. programmed device , start it, doing test via android mobile (also in network via wireless), using udp tester app store. every udp packet received , displayed on device. want test windows pc. downloaded free tool internet (packet sender). entered address , port , gave text send. device not receive @ all. strange #1. little coding in java on pc now. simple "hello world udp sender". taken directly tutorial. (activated ipv4 parameter) device not receive anything. strange #2. on windows pc have virtualbox installed ubuntu guest. start netcat within , start udp session. every single text type in appears in device. strange #3. confused , need help. miss? there setting in windows prevents simple udp packets (no broadcast) being sent host in same network? googled net did not find clue.
edit: pc seems not problem (maybe). did packet recording fritzbox , udp packets arrive there. not seem reach wireless device in home network.
i still did not figure out exact problem, think related either fritzbox and/or computers "relation" it. after updated windows 10 anniversary update, pc got new ip assigned. works.
