Key Features of Bluetooth 5.x

5.4
5.3
5.2
5.1
5.0

Bluetooth 5.x Version	Feature	Advantages	Improvement	End User Examples
v5.0	LE Coded	Robust, reliable connections indoors and outdoors	4 x Range	Whole house/building coverage/outdoor e.g. Nordic Semi tests drone connectivity to 750m outdoor range
	2M PHY	Faster data transfer, reduced TX/RX time	2 x Speed	Lower latency, increased performance & faster data transfer for critical data e.g. swifter FW updates, download of logged sensor data
	Advertising Extension (AE)	More data capacity in Connectionless Services	8 x Increase broadcast message capacity	Beacons & location/tracking services can be improved for greater data & information e.g. enhanced user experiences in facility tours
	Periodic Advertising	A more power-efficient way to perform scanning	A more power-efficient way to perform scanning	Bluetooth LE in connectionless scenarios, such as broadcast audio applications.
	High Duty Cycle Non-connectable Advertising	Reduced the minimum advertising interval for non-connectable advertising	Reduces the minimum allowed Advertising Interval from 100ms to 20ms	Allows a rapid recognition of and response to advertising packets from devices like beacons
	LE Channel Selection Algorithm #2	Improved Frequency Hopping	Improve communication reliability through reducing the probability of packet collisions	Improves performance in busy radio environments. More optimal for LE Audio and co-location of devices operating in the 2.4GHz ISM band such as Wi-Fi and other BT devices
v5.1	Enhanced Direction Finding	Angle of Arrival/Departure (AoA/AoD).	Allows Bluetooth devices to determine the direction of a Bluetooth signal transmission	AoA and AoD in conjunction with RSSI create high accuracy, interoperable positioning systems such as real-time locating systems (RTLS) and indoor positioning systems (IPS).
	GATT Caching Enhancements	Consumes less energy by allowing clients to skip service discovery when nothing has changed.	Improved Energy efficiency and user experience issues for some types of products	Bluetooth smart locks, Service discovery need only be performed the first time the user attempts to pass through a door with a smart lock. The user may perceive a delay during this first occasion but all subsequent times the user will experience a near instantaneous response from the smart lock.
	Advertising Enhancement 1: Randomized Advertising Channel Indexing	Reduces the potential for advertising packet collisions occurring	Improved scalability and reliability in busy radio environments	Improves performance in busy radio environments for co-location of devices operating in the 2.4GHz ISM band such as Wi-Fi and other BT devices
	Advertising Enhancement 2: Periodic Advertising Sync Transfer	Scanning device more energy efficient and can make possible some use cases that require precise timing in the exchange of data.	Allows resource constrained devices to utilize periodic advertising	A smartphone could scan for sync packets from a TV and then pass them over a connection to an associated smart watch so that the watch can then benefit from using periodic advertising and scanning to acquire data from the TV.
v5.2	LE Isochronous Channels (LE Audio)	Designed to support LE Audio	Allows the communication of time-bound data to one or more devices for time-synchronized processing.	LE Audio Music sharing, new standard for hearing aids and support assisted hearing systems in diverse locations, such as theaters, conferences, lecture halls, and airports, multilanguage audio systems
	Enhanced Attribute Protocol	EATT supports concurrent transactions from different applications and has security advantages over unenhanced ATT	Provides an improved user experience on devices where there are multiple applications using the Bluetooth Low Energy (LE) stack at the same time	Multiple concurrent applications such as announcements, audio and data
	LE Power Control	Possible for devices to dynamically optimize the transmission power used in communication between connected devices.	Maintain an optimal signal strength from both a signal quality and low- power-use perspective	Improves performance in busy radio environments for co-location of devices operating in the 2.4GHz ISM band such as Wi-Fi and other BT devices
v5.3	Periodic Advertising Enhancement	Improved energy efficiency and RX duty cycle	Reduced number of packets received from the controller and the associated processing requirements	All applications
	Connection Sub-Rating	Able to switch up to a high duty cycle more quickly. Connections are also able to handle variable packet rates or bursty traffic in an efficient way.	Improved user experience	Bluetooth LE Audio products such as hearing aids and monitoring systems which use sensors. Sensors which can switch the connection up to a high duty cycle quickly so that accumulated sensor data can be uploaded over a higher bandwidth connection.
	Channel Classification Enhancement	Channel classification in Bluetooth LE may now be performed by the Peripheral device as well as the Central	Improve throughput and reliability through reducing the number of potential collisions	Bluetooth LE Audio products such as streaming audio.
v5.4	Periodic Advertising with Response (PAwR)	Exchange of application data using connectionless communication	Energy efficient (Battery Life), bi-directional, communication in a large-scale one-to-many topology	Electronic Shelf Label (ESL) and applications needing to send and receive messages between a central hub device and a large number of other devices in a network
	Encrypted Advertising	Secure broadcasting of data in advertising packets	Connectionless communication or encrypted advertising and scan response packets	Broadcast topologies allowing portions of advertisement packet be exposed to any observer while other portions needing confidentiality can be read by an intended observer.
	LE GATT Security Levels Characteristic	Devices may now indicate the security mode and level required for all their GATT functionality	Adds Attribute Permissions	Door Lock for multitenant dwelling where only authorized users can access entry based on user list.
	Advertising Coding Selection	LE Extended Advertising now allows CODED Phy Selection	Longer range or higher throughput Extended Advertisement	Beacons & location/tracking services can be improved for greater data & information at longer distances or greater throughput
