Q1Domain Verified
In the context of the ESP32 BLE Mastery Course, which architectural component of the ESP32 is primarily responsible for managing the Bluetooth Low Energy stack, including connection establishment, data transfer, and event handling?
The ULP (Ultra-Low Power) Coprocessor
The Xtensa LX6 CPU cores
The dedicated Bluetooth/Wi-Fi radio module and its associated firmware
The internal SRAM and Flash memory
Q2Domain Verified
When implementing a custom BLE service on an ESP32 using the ESP-IDF BLE API, which of the following is the most accurate representation of the hierarchical structure of BLE attributes, and what is the typical role of the ESP32 in this structure?
Profile -> Service -> Characteristic -> Attribute; ESP32 typically acts as a Central.
Device -> Profile -> Service -> Characteristic; ESP32 acts as a Peripheral.
Device -> Service -> Characteristic -> Descriptor; ESP32 can act as a Central or Peripheral.
Service -> Characteristic -> Descriptor -> Handle; ESP32 can act as a Broadcaster.
Q3Domain Verified
In the context of ESP32 BLE security, specifically regarding pairing and bonding, what is the primary security implication of using "Just Works" pairing mode, and how does it differ from "Numeric Comparison" or "Passkey Entry"?
"Just Works" is primarily used for encrypted connections and does not involve pairing, making it suitable for scenarios where initial authentication is not critical, while Numeric Comparison and Passkey Entry are for initial authentication.
"Just Works" is a deprecated pairing method and should not be used in modern BLE applications, while Numeric Comparison and Passkey Entry are the recommended secure methods.
"Just Works" is vulnerable to Man-in-the-Middle (MITM) attacks because it lacks an authentication mechanism to verify the identity of the connected device, unlike Numeric Comparison and Passkey Entry which provide such verification.
"Just Works" offers the strongest security by automatically exchanging keys without user interaction, whereas Numeric Comparison and Passkey Entry require user input and are less secure.
