Detailed Description

List for storing and printing BLE scan results.

Note: This scanlist implementation is not thread safe. So calling nimble_scanlist_update() in between nimble_scanlist_get*() calls is not a good idea.

Files
file	nimble_scanlist.h
	List for keeping scanned BLE devices.

Data Structures
struct	nimble_scanlist_entry_t
	Data structure for holding a single scanlist entry. More...

Macros
#define	NIMBLE_SCANLIST_SIZE (20U)
	Default number of list entries that are allocated in RAM.

Functions
void	nimble_scanlist_init (void)

Function Documentation

nimble_scanlist_entry_t* nimble_scanlist_get_by_pos ( unsigned pos )

Get an entry of the scanlist by its position.

Parameters

[in] pos position in the list

Returns: the scanlist entry at position pos; NULL if there is no entry a the given position

nimble_scanlist_entry_t* nimble_scanlist_get_next ( nimble_scanlist_entry_t * e )

Get the next entry from the list, pass NULL for getting the first entry.

Parameters

[in] e any entry in the list

void nimble_scanlist_print_entry ( nimble_scanlist_entry_t * e )

Dump a single scanlist entry to STDIO.

Parameters

[in] e entry to dump

Add/update the entry for the a scanned node.

If the list is already full, the scanned node is simply ignored.

Parameters

[in]	type	type of the advertising packet received
[in]	addr	BLE address of the scanned node
[in]	rssi	RSSI of the received advertising packet
[in]	ad	the payload of the advertising packet
[in]	len	length of `ad`
