Detailed Description

Macro Definition Documentation

#define RF_RADIO_OP_GET_STATUS

(

a

)

(((rfc_radioOp_t *)a)->status)

Returns the current status of a running Radio Op command.

Parameters

a	A pointer with the buffer used to initiate the command

Returns

The value of the Radio Op buffer's status field

This macro can be used to e.g. return the status of a previously initiated background operation, or of an immediate command

Function Documentation

static uint8_t get_cca_info ( void  )

static

Returns CCA information.

Returns

RF_GET_CCA_INFO_ERROR if the RF was not on

On success, the return value is formatted as per the ccaInfo field of CMD_IEEE_CCA_REQ

It is the caller's responsibility to make sure the RF is on. This function will return RF_GET_CCA_INFO_ERROR if the RF is off

This function will in fact wait for a valid RSSI signal

References rf_core_send_cmd(), and rf_is_on().

static radio_value_t get_rssi ( void  )

static

Reads the current signal strength (RSSI)

Returns

The current RSSI in dBm or CMD_GET_RSSI_UNKNOWN

This function reads the current RSSI on the currently configured channel.

References rf_core_send_cmd(), and rf_is_on().

static uint8_t rf_cmd_ieee_rx ( )

static

Set up radio in IEEE802.15.4 RX mode.

Returns

RF_CORE_CMD_OK Succeeded

RF_CORE_CMD_ERROR Failed

This function assumes that cmd_ieee_rx_buf has been previously populated with correct values. This can be done through init_rf_params (sets defaults) or through Contiki's extended RF API (set_value, set_object)

References rf_core_send_cmd(), RF_RADIO_OP_GET_STATUS, and RTIMER_NOW.

static uint8_t rf_is_on ( void  )

static

Checks whether the RFC domain is accessible and the RFC is in IEEE RX.

Returns

1: RFC in RX mode (and therefore accessible too). 0 otherwise

Definition at line 249 of file ieee-mode.c.

References rf_core_is_accessible(), and RF_RADIO_OP_GET_STATUS.

static uint8_t transmitting ( void  )

static

Check the RF's TX status.

Returns

1 RF is transmitting

0 RF is not transmitting

TX mode may be triggered either by a CMD_IEEE_TX or by the automatic transmission of an ACK frame.
