Collected in a package described as VSCP & friends a complete solution framework for measurement and control, also popular known as m2m (machine to machine) and IoT (Internet of Things), is described in this paper. VSCP (Very Simple Control Protocol) defines the protocol and the framework, “Friends” is the many software tools, examples and api's the are freely available. The protocol was placed in the public domain in year 2000 when the project first was started and is therefore free to use and implement for everyone commercially or otherwise. VSCP solves the uniform discovery and uniform configurations problems for small devices. It also uses a very well specified event format and supports global unique identifiers for nodes making a node identifiable wherever it is installed in the world. It has a register model to give a flexible common interface to node configuration and a model for controlling node functionality. VSCP does not assume anything about the lower level system. It works with different transport mechanism such as Ethernet, TCP/IP, Wireless, Zigbee, Bluetooth, CAN, GPRS, RS-232, USB. Every control and measurement situation can be described and implemented using VSCP.
