setRxCallback(rx_callback_t fp)

Whenever a valid advertising packet is detected (based on any optional filters that are applied in the BLEScanner

class), a dedicated callback function (see rx_callback_t ) will be called.

The callback function has the following signature:

NOTE: ble_gap_evt_adv_report_t is part of the Nordic nRF52 SDK and is defined in ble_gap.h (https://adafru.it/y4F).

typedef void (*rx_callback_t) (ble_gap_evt_adv_report_t*);

typedef void (*stop_callback_t) (void);

bool isRunning(void);

void useActiveScan(bool enable);

void setInterval(uint16_t interval, uint16_t window);

void setIntervalMS(uint16_t interval, uint16_t window);

void restartOnDisconnect(bool enable);

void filterRssi(int8_t min_rssi);

void filterMSD(uint16_t manuf_id);

void filterUuid(BLEUuid ble_uuid);

void filterUuid(BLEUuid ble_uuid1, BLEUuid ble_uuid2);

void filterUuid(BLEUuid ble_uuid1, BLEUuid ble_uuid2, BLEUuid ble_uuid3);

void filterUuid(BLEUuid ble_uuid1, BLEUuid ble_uuid2, BLEUuid ble_uuid3, BLEUuid ble_uuid4);

void filterUuid(BLEUuid ble_uuid[], uint8_t count);

void clearFilters(void);

bool start(uint16_t timeout = 0);

bool stop(void);
