Eurotech has just released its next step beyond simple low bandwidth MQTT publish-subscribe device connectivity – Everywhere Software Framework (ESF) 3.0 , its Java OSGi software framework for M2M multiservice gateways and smart devices. It is now available for download.
According to Andrea Ceiner, Group Product Marketing Manager for the M2M/IoT line of business at Eurotech, starting with ESF release 3.0, ESF is leveraging Kura 1.0, the mature open source project donated by Eurotech to the Eclipse Foundation.
“ESF acts as the bridge between the private device network and the local network, public Internet, or cellular network,” she said. “It provides a secure, reliable and optimized data transmission mechanism between edge nodes (sensors, actuators and human-machine interfaces)and cloud platforms through M2M/IoT optimized protocols like MQTT.
She said Java software developers focused on M2M and IoT applications can take advantage of ESF software framework (Figure below ), which is fully supported by Eurotech, natively integrated with Everyware Cloud (the Eurotech’s M2M/IoT Integration Platform) and tightly integrated with industrial and rugged hardware like ReliaGATE 10-20, ReliaGATE 15-10, ReliaSENS 18-12 by Eurotech or other hardware platforms by 3rd party OEMs.
“The new features included in ESF enable a complete set of powerful remote device management operations, over MQTT, ” said Ceiner, “either on demand or on schedule, interacting with the Everyware Cloud Web Console. These include device provisioning, device update, device control, device configuration, device diagnostics and device monitoring.
“ESF offers a development environment for Java programmers that radically simplifies the creation of embedded applications,” she said, providing a set of common services for Java developers building M2M applications, including I/O access, data services, network configuration and remote management. Other new features enabled by ESF 3.0 include:
(1) PCN Bundles: the People Counter smart sensor, by Eurotech, is used in several vertical applications, from mass transportation vehicles to public places (like airports, railway stations, shopping malls) to count and monitor the flow of people in real time and perform data analysis and intelligence.
(2) Reverse NAT: this feature makes ESF's networking capabilities more powerful. Now you can hide an entire private net set of addresses/ports behind a single valid Internet address and manage the translation locally and centrally.
(3) BeagleBone Black and RaspberryPi support.
(4) Java Runtime Environment (JRE) 1.7 : always up-to-date with JRE(5) I2C, PWI, SPI, GPIO (P4J) support : the ESF’s device abstraction layer gets richer and richer and makes them available through the Java API.
(5) Eclipse Concierge OSGI Support : in addition to Equinox, ESF now supports also the new Concierge lightweight container provided under the Eclipse IOT Working group.
(6) PPP Link improvements : A new and improved version of the Paho MQTT client, included in ESF to enhance the reliability of the MQTT sessions.
(8) Everyware VPN: ESF now includes a new software service, the Everyware VPN, which allows the remote connection to devices within secure networks, enabling easy remote access to your devices through the cloud.
