Hello all. I have another problem related with Modbus TCP communication. I use STM32VG board and W5500 ethernet IC. My problem is about after i establish connection, communication is broken one time in five seconds, another time in one minute. So, connection problem is not periodic or instant. I can share my codes below. First one is initialization of TCP, second one is sending data and last one is receiving data part. I don't know why connection was broken with arbitrary timing.
