When I send > 200 Byte to the ESP32 it is reproducible every second time. If I try to send 1000 Byte I can reproduce it to 90%. It is very important, that the ESP32 receive Data on that UDP Port at the same time over WiFi! I am really sure that the STM sends data, because I add an printf to the func...

When I send data to a server via UDP (AT+CIPSENDEX) and at the same time the server sends data too, then the esp32 lost some byte of the data the STM32 sent and I do not get ...
