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; Increases the ACK frequency for asynchronous sockets

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

  • Refer to Error Codes section for the description of the above error codes Error Codes.
