Typedef Documentation

adv_data_t

using esphome::ble_device_base::adv_data_t = std::vector<uint8_t>

Definition at line 37 of file ble_device.h.

RawAdvertisementCallback

using esphome::ble_device_base::RawAdvertisementCallback

Initial value:

 
    std::function<void(const uint8_t *mac, int rssi, uint8_t addr_type, const uint8_t *data, uint16_t data_len)>

Callback for raw advertisements (the bluetooth_proxy path).

mac[] is least-significant octet first (BLE controller convention); the hub delivers on the ESPHome main loop.

Function Documentation

aes128_encrypt_block()

void esphome::ble_device_base::aes128_encrypt_block	(	const uint8_t	key[16],
		const uint8_t	in[16],
		uint8_t	out[16] )

AES-128 single-block encrypt (the same software cipher CCM uses).

Used by ESPBTDevice::resolve_irk() for the Bluetooth "ah" RPA hash, so IRK matching works identically on every platform with no chip crypto dependency.
