Function Documentation#

rsi_frame_read#

int16_t rsi_frame_read (uint8_t * pkt_buffer)

Reads response for every command and data from the module.

Parameters
[in]pkt_buffer

- pointer to buffer to which packet has to read

Returns

  • 0 - SUCCESS < 0 - FAILURE -1 - SPI busy / Timeout in case of SPI -2 - SPI Failure in case of SPI

Note

  • Enable DEBUG_PACKET_EXCHANGE macro for spi level packet exchange debug prints and MAX_PRINT_PAYLOAD_LEN for configuring no.bytes of payload to print, by default it will print 8 bytes of payload.

rsi_frame_write#

int16_t rsi_frame_write (rsi_frame_desc_t * uFrameDscFrame, uint8_t * payloadparam, uint16_t size_param)

Process a command to the wlan module.

Parameters
[in]uFrameDscFrame

- Frame descriptor

[in]payloadparam

- Pointer to the command payload parameter structure

[in]size_param

- Size of the payload for the command

Returns

  • 0 - SUCCESS < 0 - FAILURE -1 - SPI busy / Timeout in case of SPI -2 - SPI Failure in case of SPI

Note

  • Enable DEBUG_PACKET_EXCHANGE macro for spi level packet exchange debug prints and MAX_PRINT_PAYLOAD_LEN for configuring no.bytes of payload to print, by default it will print 8 bytes of payload..
