I am not sure if I am doing something wrong or if there is a bug in esp8266’s firmware.
My esp8266 is able to connect to my WiFi and when using tcp, all works fine. But I really want to use udp.
What I tried:
Now, when I try to send a udp packet to this port, I receive an ICMP packet (port unreachable). And
leads to a “type error”.
The firmware installed on esp8266 is 0018000902-AI03. Is there something wrong with it?
Does anyone has an idea about it? If it is a bug in the firmware, who knows a working firmware in terms of using udp?
