Socket configuration options.

These options can be set using Socket::set_option to configure various aspects of socket behavior including timeouts, TLS settings, PDN binding, and protocol-specific options.

Variants

ReuseAddr(i32)

Non-zero requests reuse of local addresses in bind (protocol-specific).

ReceiveTimeout(nrf_timeval)

Timeout value for socket receive and accept operations.

Minimum supported resolution is 1 millisecond.

SendTimeout(nrf_timeval)

Timeout value for socket send operation.

Minimum supported resolution is 1 millisecond.

BindToPdn(i32)

Bind this socket to a specific PDN ID.

ExceptionalData(i32)

Send data on socket as part of exceptional event.

Requires network support and PDN configuration with AT%EXCEPTIONALDATA.

KeepOpen(i32)

Keep the socket open when its PDN connection is lost, or the device is set to flight mode.

Rai(i32)

Release Assistance Indication (RAI).

Values: NRF_RAI_NO_DATA, NRF_RAI_LAST, NRF_RAI_ONE_RESP, NRF_RAI_ONGOING, NRF_RAI_WAIT_MORE

SilenceAll(i32)

Non-zero disables ICMP echo replies on both IPv4 and IPv6.

IpEchoReply(i32)

Non-zero enables ICMP echo replies on IPv4.

Ipv6EchoReply(i32)

Non-zero enables ICMP echo replies on IPv6.

Ipv6DelayedAddrRefresh(i32)

Non-zero delays IPv6 address refresh during power saving mode.

TcpServerSessionTimeout(i32)

Configure TCP server session inactivity timeout (0-135 seconds).

TlsHostName(&'a str)

Set the hostname used for peer verification.

TlsPeerVerify(i32)

Set the peer verification level.

Values: 0 (disabled), 1 (optional), 2 (required)

TlsSessionCache(i32)

Non-zero enables TLS session caching.

TlsTagList(&'a [nrf_sec_tag_t])

Set/get the security tag associated with a socket.

TlsCipherSuiteList(&'a [i32])

Set/get allowed cipher suite list.

TlsRole(i32)

Set the role for the connection (client or server).

Values: 0 (client), 1 (server)

TlsSessionCachePurge(i32)

Delete TLS session cache (write-only).

DtlsHandshakeTimeout(i32)

Set the DTLS handshake timeout.

Values: 0 (no timeout), or specific timeout values

DtlsCid(i32)

Set DTLS Connection ID setting.

Values: 0 (disabled), 1 (supported), 2 (enabled)

DtlsConnSave(i32)

Save DTLS connection (write-only).

DtlsConnLoad(i32)

Load DTLS connection (write-only).
