Hi,
I inquired about the related project in NCS2.3.0 with nRF7002-DK.
Error when using date_time on wifi
There was a problem when I updated it to NCS2.4.0.
The error occurred as shown below.
[00:00:11.323,516] <err> net_sntp: Failed to create UDP socket 23
[00:00:11.324,127] <wrn> date_time: sntp_init, error: -23
[00:00:11.324,157] <err> net_sock: invalid access on sock -1 by thread 0x200023b8
[00:00:11.336,303] <err> net_sntp: Failed to create UDP socket 23
[00:00:11.336,303] <wrn> date_time: sntp_init, error: -23
[00:00:11.336,303] <err> net_sock: invalid access on sock -1 by thread 0x200023b8
The UDP error occurs at \v2.4.0\zephyr\subsys\net\lib\sntp\sntp.c
int sntp_init(struct sntp_ctx *ctx, struct sockaddr *addr, socklen_t addr_len)
{
int ret;
if (!ctx || !addr) {
return -EFAULT;
}
memset(ctx, 0, sizeof(struct sntp_ctx));
ctx->sock.fd = zsock_socket(addr->sa_family, SOCK_DGRAM, IPPROTO_UDP);
if (ctx->sock.fd < 0) {
NET_ERR("Failed to create UDP socket %d", errno);
return -errno;
}
ret = zsock_connect(ctx->sock.fd, addr, addr_len);
if (ret < 0) {
(void)zsock_close(ctx->sock.fd);
NET_ERR("Cannot connect to UDP remote : %d", errno);
return -errno;
}
ctx->sock.fds[ctx->sock.nfds].fd = ctx->sock.fd;
ctx->sock.fds[ctx->sock.nfds].events = POLLIN;
ctx->sock.nfds++;
return 0;
}
zsock_socket uses z_impl_zsock_socket.
z_impl_zsock_socket seems to need POSIX.
So I use CONFIG_NET_SOCKETS_POSIX_NAMES, but it doesn't seem to work.
Is there a bug in NCS 2.4.0 or do I need additional settings?
I am attaching the tested code.
You need to change ssid and password.
Thank you.
