This page contains a list of device services that currently exist, are under development, or are considered archived (potentially serving as example code at best).
Virtual Device (Java): written pre-EdgeX days in Java and only partially under the Java SDK, but this service still functions as a full fledged, database driven, device service that simulates different kinds of devices to generate Events and Readings to the Core Data micro service, and allows sending commands through the Command micro service.

Random Number Generator (Go): Written with the Go SDK and demonstrates the simplest of device services - generating a random number (ints of different size) on a scheduled interval and sends the number as an Event/Reading to Core Data. It also allows the random number range to be set through a request via the Command micro service (demonstrating commands).

Modbus (Go): Written with the Go SDK. Provides generic connectivity to read and write Modbus registers and coils. This implementation works for both TCP and RTU connections (Steve O and Cloud - is this last statement true)?

Grove (C): Written with the C SDK. A device service to communicate with the Grove PI sensors.

SNMP (Go): Written with the Go SDK and used to provide data ingestion and command/control of an SNMP driven Patlite signal tower, but could easily be copied and modified to support other SNMP supported devices.
