Packet Trace (PTI)#

RAIL_PtiProtocol_t#

RAIL_PtiProtocol_t

The protocol that RAIL outputs via the Packet Trace Interface (PTI).

RAIL_ConfigPti#

RAIL_Status_t RAIL_ConfigPti (RAIL_Handle_t railHandle, const RAIL_PtiConfig_t *ptiConfig)

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

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.

PTI should be configured only when the radio is off (idle).

Note

• On EFR32 platforms GPIO configuration must be unlocked (see GPIO->LOCK register) to configure or use PTI.

RAIL_GetPtiConfig#

RAIL_Status_t RAIL_GetPtiConfig (RAIL_Handle_t railHandle, RAIL_PtiConfig_t *ptiConfig)

Get the currently-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_EnablePti#

RAIL_Status_t RAIL_EnablePti (RAIL_Handle_t railHandle, bool enable)

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

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.

PTI should be enabled or disabled only when the radio is off (idle).

Warnings

• On EFR32 platforms GPIO configuration must be unlocked (see GPIO->LOCK register) to configure or use PTI, otherwise a fault or assert might occur. If GPIO configuration locking is desired, PTI must be disabled beforehand either with this function or with RAIL_ConfigPti() using RAIL_PTI_MODE_DISABLED.

RAIL_SetPtiProtocol#

RAIL_Status_t RAIL_SetPtiProtocol (RAIL_Handle_t railHandle, RAIL_PtiProtocol_t protocol)

Set a protocol that RAIL outputs on PTI.

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.

Note

• This function cannot be called unless the radio is currently in the RAIL_RF_STATE_IDLE or RAIL_RF_STATE_INACTIVE states. For this reason, call this function early on before starting radio operations and not changed later.

RAIL_GetPtiProtocol#

RAIL_PtiProtocol_t RAIL_GetPtiProtocol (RAIL_Handle_t railHandle)

Get the protocol that RAIL outputs on PTI.

Returns

• PTI protocol in use.
