Function Documentation

rt_nfc_init()

rd_status_t rt_nfc_init

(

ri_comm_dis_init_t *const

init_data

)

Initializes NFC and configures FW, ADDR and ID records according to application_config.h constants.

Return values

RD_SUCCESS	on success.
RD_ERROR_NULL	if init_data is NULL
RD_ERROR_INVALID_STATE	if NFC is already initialized.

Returns

error code from stack on error.

rt_nfc_is_connected()

bool rt_nfc_is_connected

(

)

check if NFC is connected, i.e. a reader is in range. NFC data cannot be changed during connection, setup data to be sent while NFC is not connected.

Returns

true if NFC is connected, false otherwise.

Definition at line 319 of file ruuvi_task_nfc.c.

rt_nfc_send()

rd_status_t rt_nfc_send

(

ri_comm_message_t *

message

)

Sets given message to NFC RAM buffer. Clears previous message.

NFC data cannot be sent while NFC is connected, setup data before reader enters range.

Returns

RD_SUCCESS on success

error code from stack on error

rt_nfc_set_on_connected_isr()

void rt_nfc_set_on_connected_isr

(

const ri_comm_cb_t

cb

)

Setup connection event handler.

The event handler has signature of

void(*rt_comm_cb_t)(void* p_event_data, uint16_t event_size) 

where event data is NULL and event_size is 0. The event handler is called in interrupt context.

Parameters

[in]

cb

Callback which gets called on connection in interrupt context.

rt_nfc_set_on_disconn_isr()

void rt_nfc_set_on_disconn_isr

(

const ri_comm_cb_t

cb

)

Setup disconnection event handler.

The event handler has signature of

void(*rt_comm_cb_t)(void* p_event_data, uint16_t event_size) 

where event data is NULL and event_size is 0. The event handler is called in interrupt context.

Parameters

[in]

cb

Callback which gets called on disconnection in interrupt context.

Definition at line 304 of file ruuvi_task_nfc.c.

rt_nfc_set_on_received_isr()

void rt_nfc_set_on_received_isr

(

const ri_comm_cb_t

cb

)

Setup data received event handler.

The event handler has signature of

void(*rt_comm_cb_t)(void* p_event_data, uint16_t event_size) 

where event data is NULL and event_size is 0. The event handler is called in interrupt context.

Parameters

[in]

cb

Callback which gets called on data received in interrupt context.

Definition at line 309 of file ruuvi_task_nfc.c.

rt_nfc_set_on_sent_isr()

void rt_nfc_set_on_sent_isr

(

const ri_comm_cb_t

cb

)

Setup data sent event handler.

The event handler has signature of

void(*rt_comm_cb_t)(void* p_event_data, uint16_t event_size) 

where event data is NULL and event_size is 0. The event handler is called in interrupt context.

Parameters

[in]

cb

Callback which gets called on data sent in interrupt context.
