The task is the tranfer binary file to ESP8266 from PC by TFTP
The problem: ESP8266 is configured as "TCP server" and listens to 69 port (AT+CIPSERVER=1, 69). Sending a file by PowerShell command "tftp -i 192.168.88.244 put testBin.bin" leads to "Connection request failed". Moreover, UART doesn't see any messages (no +IPD commands), though in this case the file transmission by TFTP has to start with client's write request WRREQ
Does anyone know what could be wrong?
