Bluetooth 4.0
Divide single mode with dual mode.
Single mode can only be transmitted with BT4.0 to each other (not compatible with 3.0/2.1/2.0);D ual mode can be backwards compatible with BT4.0 transmission or 3.0/2.1/2.0 transmission
Ultra-low peak, average, and Standby mode power dissipation with enhanced coverage for up to 60 meters in maximum range.
Speed: Supports ultra-short packets at a 1Mbps data rate, at least 8 eight-bit, up to 27. All connections use the slow breathing mode (sniff subrating) added by Bluetooth 2.1 to achieve ultra-low working cycles.
Frequency hopping: minimizes crosstalk with other 2.4GHz ISM band wireless Technologies by using adaptive frequency hopping, which is common to all Bluetooth spec versions.
Master control: You can sleep longer and wake up only when you need to perform an action.
Delay: The minimum of 3 milliseconds to complete the connection settings and start transferring data.
Robustness: All packets use the 24-bit CRC checksum to ensure maximum protection against interference.
Security: Packet encryption and authentication using the AES-128 CCM encryption algorithm.
Topology: Each packet receives 32-bit addressing, theoretically connecting billions of devices, optimized for one-to-one connections, and supports a one-to-many connection to a star topology; with fast connections and disconnects, data can be transferred within a mesh topology without maintaining a complex mesh network.
