RE: Issue Facing on Sending Data Through TCP Socket Client on WiFi Network

No, unfortunately we don't have a sample project for a TCP client over Wi-Fi other than the TCP test you seem to have based your sample from, but could the http_client sample be of any use to you here perhaps.

The error message seems to indicate that there is no more buffer space available, so please try increasing the buffer size for either the Packet count or buffer count configs or potentially the NET stack size and possibly the main stack size.

Best regards,

Simon

Code:

memset(&server_addr, 0, sizeof(server_addr));

server_addr.sin_family = AF_INET;

server_addr.sin_port = htons(CONFIG_TRAFFIC_GEN_REMOTE_PORT_NUM);

if (inet_pton(AF_INET, CONFIG_TRAFFIC_GEN_REMOTE_IPV4_ADDR, &server_addr.sin_addr) <= 0)

{

LOG_ERR("Failed to set server address ");

close(sockfd);

return;

}

/* Create socket */

sockfd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

if (sockfd < 0)

{

LOG_ERR("Failed to create socket: %d", errno);

return;

}

/* Connect to the server */

err = connect(sockfd, (struct sockaddr *)&server_addr, sizeof(server_addr));

if (err < 0)

{

LOG_ERR("Failed to connect to server: %d", errno);

close(sockfd);

}

else

{

LOG_INF("Successed connect to server: %d", errno);

}

After every 1 sec send data

const char message[10] = "Hello";
ssize_t len = send(sockfd, message, sizeof(message), MSG_DONTWAIT);
if (len < 0)
{
LOG_ERR("Failed to send data: %d", errno);
} else {
LOG_INF("Sent %zd bytes to server ", len);
}

k_sleep(K_MSEC(500));
