Function

Description

SF_ChangeNetworkStandard

Changes the up-link and down-link frequency and bit rate, depending on which of the following

standards is enabled: European ETSI standard (default setting), USA FCC standard, Japanese/

Korean ARIB standard and South American FCC standard. Uses

Change_To_RCZ1 (European

ETSI),

Change_To_RCZ2 (USA FCC),Change To RCZ3 (Japanese/Korean ARIB) and

Change_To_RCZ4 (South American FCC) to set the appropriate standard.

SF_SwitchToPrivateKey

Sends the

Switch_to_Private_Key command in order to switch to the private key provided by

SIGFOX. It is used for normal RF transmission.

SF_SwitchToPublicKey

Sends the

Switch_to_Public_Key command in order to switch to the public key provided by

SIGFOX. It is used for protocol tests using SFXIQ or SNEK emulator.

SF_TransmitZeroSeq

Sends modulated zeros at currently set frequency using

PSK_ASK_Zero_Sequence command.

SF_TransmitAAAASeq

Sends modulated 0xAA at currently set frequency using

PSK_ASK_AAAA_Sequence command.

SF_SetDlFrequency

Sets down-link frequency of the SIGFOX device via

Set_DL_Frequency command.

SF_GetDlFrequency

Gets down-link frequency of the SIGFOX device via

Get_DL_Frequency command.

SF_SetFCCMacroChannel

Sets the FCC macro channel by sending the

Set_FCC_Macro_Channel command.

SF_GetFCCMacroChUsage

Gets the FCC macro channel usage by sending the

Get_FCC_Macro_Channel_Usage

command.

SF_ResetFCCMacroChannel

Restores the default macro channel settings using

Reset_FCC_Macro_Channel command.

SF_CalibrateFreqStatic

Calibrates TX frequency using

Static_Frequency_Calibration command. The passed drift offset

measured in Hz is added or subtracted to the LO when doing RF TX.

SF_UpdateTempFreqCalTable

Updates temperature frequency calibration table using the

Temperature_Frequency_Calibration

command.

SF_ReadTempFreqCalTable

Reads temperature frequency calibration table using the

Temperature_Frequency_Calibration

command.

SF_SetDefaultTempFreqCalTable

Sets default temperature frequency calibration table using the

Temperature_Frequency_Calibration command.

SF_GetLastSentRSSI

Gets the recently computed RSSI using the

Get_Last_Sent_RSSI command.

SF_GetLast30SentRSSI

Sends the

Get_Last_Sent_RSSI command to get the recently computed RSSI measure for 30

frames during RX GFSK test. This is the receiver sensitivity test.

SF_ResetLastSentRSSIBuffer

Sends the

Get_Last_Sent_RSSI command to reset the buffer, which holds the recently computed

RSSI for 30 frames during RX GFSK test. This is the receiver sensitivity test.

SF_ReadCurrentPATable

Reads current ETSI/FCC PA table using the

Update_PA_Curve command.

SF_UpdatePATable

Updates the ETSI/FCC PA table using the

Update_PA_Curve command.

SF_SetDefaultPATable

Sets default ETSI/FCC PA table using the

Update_PA_Curve command.

SF_CalibrateInitialRSSI

Sets the initial RSSI drift offset using the

Initial_RSSI_Calibration command.

SF_SendCommandNonBlock

Sends a command to the device, but does not wait for an acknowledgment. Use the

SF_HAS_CMD_ACK macro to check if the selected command has issued an ACK. Then use the

SF_Is_Ack_Frame_Ready and SF_Read_Ack_Frame_NonBlock functions to receive the ACK.

SF_IsAckFrameReady

Checks if the SIGFOX device is ready to send an acknowledgment. It checks the ACK pin value,

which is active low. The user can use the

SF_HAS_CMD_ACK macro to check if a command has

issued an acknowledgment.

SF_ReadAckFrameNonBlock

Receives an acknowledge frame. Should be used in conjunction with the

SF_Send_Command_NonBlock and SF_Is_Ack_Frame_Ready functions. Use the

SF_HAS_CMD_ACK macro to check if a command has an acknowledgment.

Peripherals setup

The following functions are placed in the sf_setup.h header file.

SF_SetupSPI

Configures a SPI module used by the SIGFOX device.

SF_SetupGPIOs

Configures the GPIOs used for the SIGFOX device. Note that this function should not be used in

SDK S32 when using the pin_mux component.
