Macro Definition Documentation

#define LE_ECALL_MSD_MAX_LEN   282

MSD message length in bytes.

Typedef Documentation

typedef struct le_ecall_Obj* le_ecall_ObjRef_t

Reference returned by Create function and used by other functions

typedef void(* le_ecall_StateChangeHandlerFunc_t)(le_ecall_State_t state, void *contextPtr)

Handler for eCall state changes.

Parameters

state	eCall state
contextPtr

typedef struct le_ecall_StateChangeHandler* le_ecall_StateChangeHandlerRef_t

Reference type for le_ecall_StateChangeHandler handler ADD/REMOVE functions

Enumeration Type Documentation

enum le_ecall_State_t

eCall session states.

Enumerator
LE_ECALL_STATE_UNKNOWN	Unknown state.
LE_ECALL_STATE_CONNECTED	Emergency call is established.
LE_ECALL_STATE_MSD_TX_COMPLETED	MSD transmission is complete.
LE_ECALL_STATE_MSD_TX_FAILED	MSD transmission has failed.
LE_ECALL_STATE_STOPPED	eCall session has been stopped by the PSAP.
LE_ECALL_STATE_RESET	eCall session has lost synchronization and starts over.
LE_ECALL_STATE_COMPLETED	Successful eCall session.
LE_ECALL_STATE_FAILED	Unsuccessful eCall session.

Function Documentation

le_ecall_StateChangeHandlerRef_t le_ecall_AddStateChangeHandler	(	le_ecall_StateChangeHandlerFunc_t	handlerPtr,
		void *	contextPtr
	)

le_ecall_StateChangeHandler handler ADD function

Parameters

[in]	handlerPtr
[in]	contextPtr

void le_ecall_ConnectService

(

void

)

Connect the client to the service

le_ecall_ObjRef_t le_ecall_Create

(

void

)

Create a new eCall object

The eCall is not actually established at this point. It is still up to the caller to call le_ecall_Start() when ready.

Returns

A reference to the new Call object.

Note

On failure, the process exits, so you don't have to worry about checking the returned reference for validity.

void le_ecall_Delete

(

le_ecall_ObjRef_t

ecallRef

)

Call to free up a call reference.

Note

This will free the reference, but not necessarily stop an active eCall. If there are other holders of this reference then the eCall will remain active.

Parameters

[in]

ecallRef

eCall reference

void le_ecall_DisconnectService

(

void

)

Disconnect the client from the service

le_result_t le_ecall_End

(

le_ecall_ObjRef_t

ecallRef

)

End the current eCall session

Returns

LE_OK on success

LE_DUPLICATE the eCall session was started by another application

LE_FAULT for other failures

Parameters

[in]

ecallRef

eCall reference

le_ecall_State_t le_ecall_GetState

(

le_ecall_ObjRef_t

ecallRef

)

Get the current state for the given eCall

Returns

The current state for the given eCall

Note

The process exits, if an invalid eCall reference is given

Parameters

[in]

ecallRef

eCall reference

le_result_t le_ecall_ImportMsd	(	le_ecall_ObjRef_t	ecallRef,
		const uint8_t *	msdPtr,
		size_t	msdNumElements
	)

Import an already prepared MSD.

MSD is transmitted only after an emergency call has been established.

Returns

LE_OK on success

LE_DUPLICATE an MSD has been already imported

LE_FAULT for other failures

Note

On failure, the process exits, so you don't have to worry about checking the returned reference for validity.

Parameters

[in]	ecallRef	eCall reference
[in]	msdPtr	the prepared MSD
[in]	msdNumElements

void le_ecall_RemoveStateChangeHandler

(

le_ecall_StateChangeHandlerRef_t

addHandlerRef

)

le_ecall_StateChangeHandler handler REMOVE function

Parameters

[in]

addHandlerRef

le_result_t le_ecall_SetMsdPassengersCount	(	le_ecall_ObjRef_t	ecallRef,
		uint32_t	paxCount
	)

Set the number of passengers transmitted by the MSD.

MSD is transmitted only after an emergency call has been established.

Returns

LE_OK on success

LE_DUPLICATE an MSD has been already imported

LE_FAULT for other failures

Note

The process exits, if an invalid eCall reference is given

Parameters

[in]	ecallRef	eCall reference
[in]	paxCount	number of passengers

le_result_t le_ecall_SetMsdPosition	(	le_ecall_ObjRef_t	ecallRef,
		bool	isTrusted,
		int32_t	latitude,
		int32_t	longitude,
		int32_t	direction
	)

Set the position transmitted by the MSD.

MSD is transmitted only after an emergency call has been established.

Returns

LE_OK on success

LE_DUPLICATE an MSD has been already imported

LE_FAULT for other failures

Note

The process exits, if an invalid eCall reference is given

Parameters

[in]	ecallRef	eCall reference
[in]	isTrusted	true if the position is accurate, false otherwise
[in]	latitude	latitude in degrees with 6 decimal places, positive North
[in]	longitude	longitude in degrees with 6 decimal places, positive East
[in]	direction	direction in degrees (where 0 is True North)

le_result_t le_ecall_StartAutomatic

(

le_ecall_ObjRef_t

ecallRef

)

Start an automatic eCall session

Returns

LE_OK on success
