- Socket descriptor ID

Returns

Void

ROM_WL_rsi_get_application_socket_descriptor#

int32_t ROM_WL_rsi_get_application_socket_descriptor (global_cb_t * global_cb_p, int32_t sock_id)

Get the application socket descriptor from module socket descriptor. This is a non-blocking API.

Parameters

[in]	global_cb_p	- Pointer to the global control block
[in]	sock_id	- Module's socket descriptor

Returns

Positive value - Application index Negative value - If index is not found

ROM_WL_rsi_get_primary_socket_id#

int32_t ROM_WL_rsi_get_primary_socket_id (global_cb_t * global_cb_p, uint16_t port_number)

Get socket descriptor from port_number. This is a non-blocking API.

Parameters

[in]	global_cb_p	- Pointer to the global control block
[in]	port_number	- Port number

Returns

Positive value - Socket descriptor Negative value - If socket is not found

ROM_WL_calculate_buffers_required#

uint8_t ROM_WL_calculate_buffers_required (global_cb_t * global_cb_p, uint8_t type, uint16_t length)

Calculate number of buffers required for the data packet. This is a non-blocking API.

Parameters

[in]	global_cb_p	- Pointer to the global control block
[in]	type	- Type of socket to create
[in]	length	- Length of the message

Returns

The number of buffers required for a data packet

ROM_WL_calculate_length_to_send#

uint16_t ROM_WL_calculate_length_to_send (global_cb_t * global_cb_p, uint8_t type, uint8_t buffers)

Caluculate the msg length sent using available buffers. This is a non-blocking API.

Parameters

[in]	global_cb_p	- Pointer to the global control block
[in]	type	- Type of the socket stream
[in]	buffers	- Available buffers

Returns

Length - Length available in the buffer for msg.

rsi_socket_config#

int32_t rsi_socket_config (void )

Set the socket configuration parameters. Using this command (optional) is highly recommended. Based on the socket configuration, module will use available buffers effectively. This is a blocking API.

Parameters

N/A


Parameters	Description
total socket	Desired total number of sockets to open
total_tcp_sockets	Desired total number of TCP sockets to open
total_udp_sockets	Desired total number of UDP sockets to open
tcp_tx_only_sockets	Desired total number of TCP sockets to open which are used only for data transmission
tcp_rx_only_sockets	Desired total number of TCP sockets to open which are used only for data reception
udp_tx_only_sockets	Desired total number of UDP sockets to open which are used only for data transmission
udp_rx_only_sockets	Desired total number of UDP sockets to open which are used only for data reception
tcp_rx_high_performance_sockets	Desired total number of high performance TCP sockets to open. High performance sockets can be
allocated with more buffers based on the buffers availability. This option is valid only for TCP
data receive sockets. Socket can be opened as high performance by setting high performance bit in
socket create command.
tcp_rx_window_size_cap	Desired total to increase the TCP RX window size
tcp_ack_window_div_factor	In case of high latency networks to configure the TCP ACK division factor with respective to the
window size
Note:
Default value is tcp_rx_window_size_cap.

The following conditions must be met: total_sockets <= Maximum allowed sockets(10) (total_tcp_sockets + total_udp_sockets) <= total_sockets (total_tcp_tx_only_sockets + total_tcp_rx_only_sockets) <= total_tcp_sockets (total_udp_tx_only_sockets + total_udp_rx_only_sockets) <= total_udp_sockets total_tcp_rx_high_performance_sockets <= total_tcp_rx_only_sockets

Must be given after IP configuration command and before any socket creation.

Returns

Zero - Success Non-Zero Value - Failure If return value is greater than 0 0x0021,0x0025,0x002C,0xFF6D

Note
