Posted on August 16, 2017 at 00:58Dear Forum,
I bring forth a frustration question yet I'm uncertain how to approach it.
I have STM32F402, and I can communication over UDP . In cube I reviewed every options but my problem do not solved.
If I can
sending data over UDP
smaller than 1514 byte is every OK - I have Java applicaton to
receive and
monitoring data from UDP and works good , but if I can send over 1514 byte in wireshark seeing every fragmented data and full packet good . But in PC doesnt see any packet. Maybe problem is in header or fragmentation .. I dont know.
Please help me.
My code :
void udpinit(void){
udp_p = udp_new();
udp_bind(udp_p,IP_ADDR_ANY,port);
udp_connect(udp_p, IP_ADDR_BROADCAST, port);
}
void packet_send(void){
struct pbuf *TxBuffer_p;
TxBuffer_p = pbuf_alloc(PBUF_TRANSPORT, sizeof(adc_data), PBUF_RAM);
memcpy(TxBuffer_p->payload,adc_data,sizeof(adc_data));
udp_send(udp_p,TxBuffer_p);
pbuf_free(TxBuffer_p);
}
