In a single-channel configuration, only one module at a time can transfer information to the CPU. In multi-channel configurations, multiple modules can transfer information to the CPU at the same time, in parallel. FPM, EDO, SDR, and RDRAM memory was not commonly installed in a dual-channel configuration.
The host stack is generally implemented as part of an operating system, or as an installable package on top of an operating system. For integrated devices such as Bluetooth headsets, the host stack and controller stack can be run on the same microprocessor to reduce mass production costs; this is known as a hostless system.
A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack. Bluetooth stacks can be roughly divided into two distinct categories: General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers .
It includes Classic Bluetooth, Bluetooth high speed and Bluetooth Low Energy (BLE) protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols. Bluetooth Low Energy, previously known as Wibree, [95] is a subset of Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple ...
For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies. A host operating system can expose a basic set of profiles (namely OBEX, HID and Audio Sink) and manufacturers can add additional profiles to their drivers and stack to enhance what their Bluetooth devices can do. Devices such as mobile phones can ...
32-bit MIPS-M4K PIC32MX processor boards (40-80 MHz). The Arduino libraries have been implemented natively for the PIC32MX and these kits run in a fork of the standard Arduino IDE, MPIDE [228] and are compatible to most shields.

Bluetooth V4.0 with standard protocol and with low energy protocol; IEEE 802.15.4-2006 (low-level protocol definitions corresponding to the OSI model physical and link layers. Zigbee, 6LoWPAN, etc. build upward in the protocol stack and correspond to the network and transport layers.) Thread (network protocol) UWB; Wireless USB; Zigbee; ANT+
Cypress also provides a complete Bluetooth Low Energy stack licensed from Mindtree with both Peripheral and Central functionality. [8] The PSoC 6 series includes versions with BLE including Bluetooth 5 features including extended range or higher speed.
