Function Documentation

RAIL_Status_t RAIL_ConfigPti ( RAIL_Handle_t railHandle,
const RAIL_PtiConfig_t * ptiConfig
)

Configures PTI pin locations, serial protocols, and baud rates.

Parameters
[in] railHandle A RAIL instance handle (currently not used).
[in] ptiConfig A configuration structure applied to the relevant PTI registers. A NULL ptiConfig will produce undefined behavior.
Returns
Status code indicating success of the function call.

This method must be called before RAIL_EnablePti() is called. Although a RAIL handle is included for potential future expansion of this function, it is currently not used. That is, there is only one PTI configuration that can be active on a chip, regardless of the number of protocols (unless the application updates the configuration upon a protocol switch), and the configuration is not saved in the RAIL instance. For optimal future compatibility, pass in a chip-specific handle, such as RAIL_EFR32_HANDLE .

RAIL_Status_t RAIL_EnablePti ( RAIL_Handle_t railHandle,
bool enable
)

Enables Packet Trace Interface (PTI) output of packet data.

Parameters
[in] railHandle A RAIL instance handle (currently not used).
[in] enable PTI is enabled if true; disable if false.
Returns
RAIL status indicating success of the function call.

Similarly to having only one PTI configuration per chip, PTI can only be enabled or disabled for all protocols. It cannot be individually set to enabled and disabled per protocol (unless the application switches it when the protocol switches), and enable/disable is not saved as part of the RAIL instance. For optimal future compatibility, pass in a chip-specific handle, such as RAIL_EFR32_HANDLE .

RAIL_Status_t RAIL_GetPtiConfig ( RAIL_Handle_t railHandle,
RAIL_PtiConfig_t * ptiConfig
)

Gets the currently active PTI configuration.

Parameters
[in] railHandle A RAIL instance handle (currently not used).
[out] ptiConfig A configuration structure filled with the active PTI configuration.
Returns
RAIL status indicating success of the function call.

Although most combinations of configurations can be set, it is safest to call this method after configuration to confirm which values were actually set. As in RAIL_ConfigPti, railHandle is not used. This function always returns the single active PTI configuration regardless of the active protocol. For optimal future compatibility, pass in a chip specific handle, such as RAIL_EFR32_HANDLE .

RAIL_Status_t RAIL_SetPtiProtocol ( RAIL_Handle_t railHandle,
RAIL_PtiProtocol_t protocol
)

Sets a protocol that RAIL outputs on PTI.

Parameters
[in] railHandle A RAIL instance handle.
[in] protocol The enumeration representing which protocol the node is using.
Returns
Status code indicating success of the function call.

The protocol is output via PTI for each packet. Before any protocol is set, the default value is RAIL_PTI_PROTOCOL_CUSTOM . Use one of the enumeration values so that the Network Analyzer can decode the packet.
