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).
Current Device Services
...
Modbus (
...
Go):
...
Written with the Go SDK. Provides generic connectivity to read and write Modbus input status, coils, input registers and holding registers. This implementation works for both TCP and RTU connections.

...
...
MQTT (Go): Written with the Go SDK
...
. Provides the connectivity to listen to and publish to the specific MQTT topics.

...
Modbus SNMP (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)?and used to provide data ingestion and command/control of a Dell N-series PoE switch. Future development plans include abstraction for use with other switch types.

Grove (C): Written with the C SDK. A device service to communicate with the Grove PI sensors.
https://github.com/edgexfoundry/device-grove-c
Developed & In EdgeX Holding (approval needed by TSC to make part of EdgeX)
Virtual Device (Go): Written with the Go SDK. This device service simulates different kinds of devices with different data types to generate Events and Readings to the Core Data micro service, and allows sending commands through the Command micro service.
https://github.com/edgexfoundry/device-virtual-go
Camera 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 devicesaccess to still images and RTP video streams from ONVIF compliant IP cameras. Also provides access to metadata on Axis cameras.

In Development
Contact the party associated with the development to get more background, status and potentially early code drops.
REST(Go): Written with the Go SDK. This device service provides easy way for 3rd party applications, such as Point of Sale, CV Analytics, etc., to push data into EdgeX via the REST protocol. The current implementation is meant for one-way communication into EdgeX via async readings.

BACnet (C): Wirtten with the C SDKOPC UA (C): being developed by IoTech. A device service to communicate with OPC UA BACnet sensors/devices (IP and MSTP)
https://github.com/edgexfoundry/device-bacnet-c
CoAP BACnet (C): being developed by IoTechWritten with the C SDK. A device service to communicate with BACnet sensors/devices.do specialized Internet Application Protocol for constrained devices.
https://github.com/edgexfoundry/device-coap-c
GPIO Bluetooth Low Energy (Go): being developed by Dell Technologies. A device service to communicate with BLE devices/sensors.
Bluetooth Low Energy (C): being developed by IoTech. A device service to communicate with BLE devices/sensors.
Written with the Go SDK. GPIO is a standard interface used to connect microcontrollers to other electronic devices. It is also very popular with Raspberry Pi adopters given its availability on the devices.

LLRP / RFID (Go): Low Level Reader Protocol (LLRP) is a standardized network interface to many RFID readers.
https://github.com/edgexfoundry/device-rfid-llrp-go
In Development
Contact the party associated with the development to get more background, status and potentially early code drops.
UART (GoZigBee (C): being developed by IoTech. A device service to communicate with ZigBee devices/sensors.
...
Jianxing Intelligence in Go. Universal Asynchronous Receiver/Transmitter (UART) is serial data communications and is used in modems and can be used with USB in a USB to UART bridge.
https://github.com/edgexfoundry-holding/device-uart
OPC UA (C): being developed by IoTech using the C SDK. A device service to communicate with
...
OPC UA sensors/devices.

Archived (device services no longer supported or potentially functioning)
...
Bacnet (Java): https://github.com/edgexfoundry/device-bacnet
Random Number Generator (Go): https://github.com/edgexfoundry/device-random Archived and moved to edgex-examples. 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).
