pm_peer_data_load()

uint32_t pm_peer_data_load	(	uint16_t	peer_id,
		enum pm_peer_data_id	data_id,
		void *	data,
		uint32_t *	len )

#include <peer_manager.h>

Retrieve the stored data of a peer.

Note

The length of the provided buffer must be a multiple of 4 bytes.

Parameters

[in]	peer_id	Peer ID to get data for.
[in]	data_id	Which type of data to read.
[out]	data	Where to put the retrieved data. The documentation for pm_peer_data_id specifies what data type each data ID is stored as.
[in,out]	len	In: The length in bytes of data. Out: The length in bytes of the read data, if the read was successful.

Return values

NRF_SUCCESS	If the data was read successfully.
NRF_ERROR_INVALID_PARAM	If the data type or the peer ID was invalid or unallocated.
NRF_ERROR_NULL	If a pointer parameter was NULL.
NRF_ERROR_NOT_FOUND	If no stored data was found for this peer ID/data ID combination.
NRF_ERROR_DATA_SIZE	If the provided buffer was not large enough. The data is still copied, filling the provided buffer. Note that this error can occur even if loading the same size as was stored, because the underlying layers round the length up to the nearest word (4 bytes) when storing.
NRF_ERROR_INVALID_STATE	If the Peer Manager is not initialized.
