W5500 UDP problem

Question

I am trying to interface W5500 with STM32f103c8t6 using UDP . Problem is I can’t send data trough UDP socket but I can receive data from the UDP socket . Please help me to solve the problem Thank you

There is not enough information in the question. You have now written a question on the W5500 Ethernet Shield category. Are you using the W5500 Ethernet Shield? Anyway, we need to know what code you used to help you. In addition, we need information about what settings you have set up to send and receive data.

Hi i have following Wiznet W5100 board http://www.ebay.in/itm/112321091012?aff_source=Sok-Goog and i am interfacing it following STM32 Board using UDP STMicroelectronics STM32VLDISCOVERY - STMicroelectronics STM32VLDISCOVERY - Discovery kit with STM32F100RB MCU, STM32VLDISCOVERY, STMicroelectronics I am trying to make an Echo server. Whatever data is sent to my chip via W5500 , data is returned back to the PC. I have a C# program written by myself to send and receive data using UDP socket. I am Monitoring communication by Wireshark. UDP send from PC is working ok. i can see the data sent in wireshark and data is received without any problem in my C program. But when i send the data back to the PC, Function SendData is stuck inside while(1) loop such that Sok_0_INTR_Value is always 0x04. I neither get timeout or send_ok.Please drop me a word if possible Thank You #define BSB_Common_Reg 0b00000 // Block Selection Bits - Common Reg #define BSB_Sok_0_Reg 0b00001 #define Wiz_CS GPIO_Pin_3 // Port A #define Wiz_RST GPIO_Pin_2 // Port A unsigned volatile char DataRecieved = 0 ; // To be changed by Socket Interrupt = Volatile int main(void) { LEDSetup(); SPI1_setup(); ExtInterruptLineConfig(); Wiz_Setup_A_INIT(); Wiz_Setup_B_OPEN(); unsigned short RecvCount = 0 ; unsigned short Count = 0 ; unsigned char Data[64]; unsigned char SCADAInfo[8]; while(1) { GPIO_SetBits(GPIOC, GPIO_Pin_8 | GPIO_Pin_9 ); Delay(1,500); GPIO_ResetBits(GPIOC, GPIO_Pin_8 | GPIO_Pin_9 ); Delay(1,500); RecvCount = DataRecievedCheck(); if( RecvCount ) { GetData(Data , &Count ,SCADAInfo); // Recieve Data SendData(Data ,Count ); __disable_irq(); RecvCount = 0 ; // Atomic __enable_irq(); Wiz_Setup_B_OPEN(); // Wiz UDP = Open-Close Socket every Time.

This is a working UDP code both by polling and interrupt , tested on STM32F100RB #include #include #include #include #include #include #include #include // ip.addr == 192.168.1.12 void Wiz_Write_Multi( unsigned short , unsigned char , unsigned char * , unsigned short ) ; // , , Pointer , Array Count void Wiz_Read_Multi( unsigned short , unsigned char , unsigned char *, unsigned short ) ; // , , Pointer , Array Count void LEDSetup(void); void SPI1_setup(void); void SPI_SendBye(unsigned char); unsigned char SPI_ReadByte(); void Tim2_init(unsigned char); void Delay( unsigned char , unsigned short); // 0 = Micro , 1 = Mili void Wiz_Setup_A_INIT(void); void Wiz_Setup_B_OPEN(void); void ExtInterruptLineConfig(void) ; void GetData(unsigned char* , unsigned short* , unsigned char*); unsigned char SendData(unsigned char* , unsigned short); unsigned short DataRecievedCheck(void); #define BSB_Common_Reg 0b00000 // Block Selection Bits - Common Reg #define BSB_Sok_0_Reg 0b00001 #define Wiz_CS GPIO_Pin_3 // Port A #define Wiz_RST GPIO_Pin_2 // Port A // __disable_irq();RecvCount = 0 ; // Atomic __enable_irq(); unsigned volatile char DataRecieved = 0 ; // To be changed by Socket Interrupt = Volatile int main(void) { LEDSetup(); SPI1_setup(); ExtInterruptLineConfig(); Wiz_Setup_A_INIT(); Wiz_Setup_B_OPEN(); unsigned short RecvCount = 0 ; unsigned short Count = 0 ; unsigned char Data[64]; unsigned char SCADAInfo[8]; while(1) { GPIO_SetBits(GPIOC, GPIO_Pin_8 | GPIO_Pin_9 ); Delay(1,500); GPIO_ResetBits(GPIOC, GPIO_Pin_8 | GPIO_Pin_9 ); Delay(1,500); // RecvCount = DataRecievedCheck(); // if( RecvCount ) Polling if( DataRecieved ) // Interrupt { DataRecieved = 0 ; GetData(Data , &Count ,SCADAInfo); // Recieve Data = Closes Soket in the end Wiz_Setup_B_OPEN(); SendData(Data ,Count ); // Send Data = Closes Soket in the end Wiz_Setup_B_OPEN(); // Wiz UDP =…

Well then develop the TCP code with Interrupt , test it and share it with me…
