Radio frequency communication (RFCOMM) The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port ...
Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs).
IEEE Std 802.15.3d-2017 defines an alternative physical layer (PHY) at the lower THz frequency range between 252 GHz and 325 GHz for switched point-to-point links is defined in this amendment. Two PHY modes are defined that enable data rates of up to 100 Gb/s using eight different bandwidths between 2.16 GHz and 69.12 GHz.
Apache Mynewt NimBLE is a full-featured, open source Bluetooth Low Energy 4.2 and 5.0 protocol stack written in C for embedded systems. NimBLE is one of the most complete protocol stacks, supporting 5.0 features including high data rate and extended advertising. The implementation supports all layers of the Bluetooth protocol.
That's going to change very shortly with the advent of Bluetooth's new 4.2 spec. If a sensor, smart light bulb or other low-power device supports the new technology, it can connect directly to the ...
