• Bluetooth 5.x. With respect to BLE, it provides options that can double the
speed (2 Mb/s burst) at the expense of range, or up to fourfold the range at
the expense of data rate, and eightfold the data broadcasting capacity of transmissions, by increasing the packet lengths. The increase in transmissions could
be important for IoT devices, where many nodes connect throughout the same
environment. Bluetooth 5 adds functionality for connectionless services such as
location-relevant navigation of low-energy Bluetooth connections. Bluetooth 5.1
introduces direction-finding to improve localization accuracy.
To specify interoperability between Classic Bluetooth and BLE, Bluetooth 4.0
introduces two different configurations:
• Single-mode (BLE, Bluetooth Smart) device. A device that implements BLE and
can communicate with single-mode and dual-mode devices, but not with devices
supporting Classic Bluetooth only.
• Dual-mode (BR/EDR/LE, Bluetooth Smart Ready) device. A device that implements both Classic Bluetooth and BLE and can communicate with any Bluetooth
device.
Figure 3.10 in three different columns shows logos, protocol stacks, and interoperation modes of Classic Bluetooth, Bluetooth Smart Ready, and Bluetooth Smart.
