Public Member Functions
void	setup () override

void	loop () override

void	dump_config () override

float	get_setup_priority () const override

void	enable ()
	Bring up the LN882H BLE stack (one-time; the SDK has no teardown path).

bool	is_active () const

void	set_enable_on_boot (bool enable_on_boot)

void	get_mac_lsb_first (uint8_t out[6]) const
	Controller BLE address in the SDK's ln_bd_addr_t order: least-significant octet first (the BLE/HCI convention).

void	register_scan_listener (BLEScanListener *listener)
	Register a consumer for scan reports (delivered on the main task via loop()).

void	scan_start (uint16_t interval, uint16_t window, bool active)
	Start the controller scan.

void	scan_stop ()
	Stop the controller scan (no-op when not scanning).

BLEScanReport *	allocate_scan_report ()
	Internal, SDK rw-task event-callback context: allocate a pool slot for a scan report.

void	push_scan_report (BLEScanReport *report)
	Internal: hand a filled slot to the main-task queue (cannot fail — the pool is sized to the queue capacity).

void	count_rejected_report ()
	Internal, rw-task context: count a report rejected by the legacy-only filter, so a wrong assumption about the stack's report encoding shows up in verbose logs instead of as a scanner that silently reports nothing.

Member Function Documentation

◆ allocate_scan_report()

BLEScanReport * esphome::ln882h_ble::LN882HBLE::allocate_scan_report ( )

Internal, SDK rw-task event-callback context: allocate a pool slot for a scan report.

Returns nullptr (and counts the drop) when the queue is full; the callback fills the slot in place — no intermediate copy.

Definition at line 251 of file ln882h_ble.cpp.

◆ count_rejected_report()

void esphome::ln882h_ble::LN882HBLE::count_rejected_report ( )

inline

Internal, rw-task context: count a report rejected by the legacy-only filter, so a wrong assumption about the stack's report encoding shows up in verbose logs instead of as a scanner that silently reports nothing.

Definition at line 116 of file ln882h_ble.h.

◆ dump_config()

void esphome::ln882h_ble::LN882HBLE::dump_config ( )

overridevirtual

Reimplemented from esphome::Component.

Definition at line 377 of file ln882h_ble.cpp.

◆ enable()

void esphome::ln882h_ble::LN882HBLE::enable ( )

Bring up the LN882H BLE stack (one-time; the SDK has no teardown path).

Requires setup() to have run: rw_init() is handed the address resolved there. Blocks ~120 ms across the SDK's settle points, so calling it from loop() (enable_on_boot: false) trips the loop-blocking warning once.

Definition at line 285 of file ln882h_ble.cpp.

◆ get_mac_lsb_first()

void esphome::ln882h_ble::LN882HBLE::get_mac_lsb_first ( uint8_t out[6] ) const

Controller BLE address in the SDK's ln_bd_addr_t order: least-significant octet first (the BLE/HCI convention).

Reverse for printable form — the byte order is in the name so platform analogs cannot be confused (the bk72xx sibling exposes the same accessor).

Definition at line 375 of file ln882h_ble.cpp.

◆ get_setup_priority()

float esphome::ln882h_ble::LN882HBLE::get_setup_priority ( ) const

overridevirtual

Reimplemented from esphome::Component.

Definition at line 283 of file ln882h_ble.cpp.

◆ is_active()

bool esphome::ln882h_ble::LN882HBLE::is_active ( ) const

inline

Definition at line 81 of file ln882h_ble.h.

◆ loop()

void esphome::ln882h_ble::LN882HBLE::loop ( )

overridevirtual

Reimplemented from esphome::Component.

Definition at line 331 of file ln882h_ble.cpp.

◆ push_scan_report()

void esphome::ln882h_ble::LN882HBLE::push_scan_report ( BLEScanReport * report )

Internal: hand a filled slot to the main-task queue (cannot fail — the pool is sized to the queue capacity).

Definition at line 261 of file ln882h_ble.cpp.

◆ register_scan_listener()

void esphome::ln882h_ble::LN882HBLE::register_scan_listener ( BLEScanListener * listener )

inline

Register a consumer for scan reports (delivered on the main task via loop()).

Storage is codegen-sized: the consumer's codegen requests a slot via request_scan_listener_slot(), which emits LN882H_BLE_SCAN_LISTENER_COUNT.

Definition at line 95 of file ln882h_ble.h.

◆ resolve_mac_()

void esphome::ln882h_ble::LN882HBLE::resolve_mac_ ( )

protected

Definition at line 390 of file ln882h_ble.cpp.

◆ scan_start()

void esphome::ln882h_ble::LN882HBLE::scan_start	(	uint16_t	interval,
		uint16_t	window,
		bool	active )

Start the controller scan.

Interval/window are in BLE units (0.625 ms); active enables scan requests on the 1M PHY. Enables the stack first if needed. Scans the legacy 1M PHY only (extended/coded PHY advertisements exceed the legacy 62-byte framing consumers are sized for).

Definition at line 433 of file ln882h_ble.cpp.

◆ scan_stop()

void esphome::ln882h_ble::LN882HBLE::scan_stop ( )

Stop the controller scan (no-op when not scanning).

Definition at line 464 of file ln882h_ble.cpp.

◆ set_enable_on_boot()

void esphome::ln882h_ble::LN882HBLE::set_enable_on_boot ( bool enable_on_boot )

inline

Definition at line 83 of file ln882h_ble.h.

◆ setup()

void esphome::ln882h_ble::LN882HBLE::setup ( )

overridevirtual

Reimplemented from esphome::Component.
