Dear Sebastian, thank you very much for the detailed answer. I already tested its working better now.
I don't want to bother you, but is there a way to get the details (like the dump when I type udp send fe80::212:4b00:14b5:f3da 8080 0x1[data]) actually the RSSI and LQI with UDP sock API (sock_udp_recv)?
