App Utility#

The App BT Mesh Utility provides collection of stateless utility functions and macros to solve recurring tasks in the BT Mesh components and examples. This component supports logging of missing application key binding and missing model publication data configuration errors. The logging level of these errors are configurable. This component is suitable for use in both NCP and SOC applications.

Function Documentation#

app_btmesh_nvm_init#

sl_status_t app_btmesh_nvm_init (void )

Parameters

Type	Direction	Argument Name	Description
void	N/A

Initializes the NVM interface.

Calls the default initializer of NVM3.

Returns

Status code

Return values

SL_STATUS_OK: In case of success
SL_STATUS_ALREADY_INITIALIZED: In case it was initialized earlier with parameters different from default

app_btmesh_nvm_read#

sl_status_t app_btmesh_nvm_read (uint16_t key, void * buf, size_t * len)

Parameters

Type	Direction	Argument Name	Description
uint16_t	[in]	key	Identifier of the data.
void *	[out]	buf	Buffer to the data to read.
size_t *	[inout]	len	Pointer to the length of the read data. As in input it takes the length of buffer. As an output it contains the length of the read data.

Reads data from NVM.

Returns

Status code

Return values

SL_STATUS_OK: In case of success
SL_STATUS_INVALID_STATE: In case NVM has not been initialized
SL_STATUS_INVALID_KEY: In case key is invalid
SL_STATUS_NOT_FOUND: In case key has not been found
SL_STATUS_INVALID_PARAMETER: In case any of the input parameters is invalid

app_btmesh_nvm_write#

sl_status_t app_btmesh_nvm_write (uint16_t key, const void * buf, size_t len)

Parameters

Type	Direction	Argument Name	Description
uint16_t	[in]	key	Identifier of the data.
const void *	[in]	buf	Buffer to the data to write.
size_t	[in]	len	Length of the data in the buffer.

Writes data into the NVM.

Returns

Status code

Return values

SL_STATUS_OK: In case of success
SL_STATUS_INVALID_STATE: In case NVM has not been initialized
SL_STATUS_FULL: In case NVM is full
SL_STATUS_NO_MORE_RESOURCE: In case NVM doesn't have the resources to store the data
SL_STATUS_FLASH_PROGRAM_FAILED: In case writing to NVM has failed
SL_STATUS_INVALID_PARAMETER: In case any of the input parameters is invalid

app_btmesh_nvm_erase#

sl_status_t app_btmesh_nvm_erase (uint16_t key)

Parameters

Type	Direction	Argument Name	Description
uint16_t	[in]	key	Identifier of the data.

Erases data from NVM.

Returns

Status code

Return values

SL_STATUS_OK: In case of success
