void wiz_send_data ( uint8_t  sn,
uint8_t *  wizdata,
uint16_t  len 
)

It copies data to internal TX memory.

This function reads the Tx write pointer register and after that, it copies the wizdata(pointer buffer) of the length of len(variable) bytes to internal TX memory and updates the Tx write pointer register. This function is being called by send() and sendto() function also.

Note
User should read upper byte first and lower byte later to get proper value.
Parameters
(uint8_t)snSocket number. It should be 0 ~ 7.
wizdataPointer buffer to write data
lenData length

void wiz_recv_data ( uint8_t  sn,
uint8_t *  wizdata,
uint16_t  len 
)

It copies data to your buffer from internal RX memory.

This function read the Rx read pointer register and after that, it copies the received data from internal RX memory to wizdata(pointer variable) of the length of len(variable) bytes. This function is being called by recv() also.

Note
User should read upper byte first and lower byte later to get proper value.
Parameters
(uint8_t)snSocket number. It should be 0 ~ 7.
wizdataPointer buffer to read data
lenData length

void wiz_recv_ignore ( uint8_t  sn,
uint16_t  len 
)

It discard the received data in RX memory.

It discards the data of the length of len(variable) bytes in internal RX memory.

Parameters
(uint8_t)snSocket number. It should be 0 ~ 7.
