Mehfuz just published an initial NativeScript Plugin to call into the RFID libraries in the Invengo XC-1003 (see Part I for details of the device). Mehfuz also published a simple NativeScript App that uses the Plugin to read a tag and display it.
Our ThingMagic Sargas just arrived. This is a small (87mm x 80 mm x ) fixed RFID reader that packs a nice punch. It has 2 high performance UHF RFID antenna ports capable of reading 750 tags a second at distances over 9 meters and an ethernet port, but it also has a BLE, USB, 4 GPIOs, micro-SD, and HDMI. Inside there is a 1GHz ARM Cortex 8 running Linux (Debian) where you can run your own code.
The Invengo XC-1003 is an Android Smartphone (KitKat) with an UHF RFID reader/writer. Ours just showed up yesterday from AtlasRFID. Invengo positions it as a Mobile IoT device, advertising it as working on “the RAIN RFID Frequency 865-868MHz (ETSI) – 902-928MHz (FCC)”.
The CSUMB Capstone project for Fall 2016 is a Digitally Connected Capstone Festival App using RFID Tags and Antennas, iBeacons and Mobile Apps.
The basic architecture is sensors connected to an Activity Management platform to track the real-time activities interacting with a Mobile Application used by the public and presenters at the Festival. The project will leverage lessons learned from the Capstone project in Spring 2016, Quantifying the BIT Building, and two previous projects: the ProgressNEXT app and a NativeScript MeetUp in Palo Alto.
The bulk of the sensor data will be from RFID tags worn by the attendees to the Festival, but additional data may come via mobile apps, reading BLE beacon proximity data and/or Geolocation data. The Activity information will be used by mobile applications that may also provide information on the different presentations and events.
I put together a quick presentation on Using IOT for Digital Activity Monitoring. I’ll refine it when I have an opportunity of presenting it, but, for now, check the slides at Slideshare. See this Umbrella Post for quick links to some other related posts.
IOT-based Activity Monitoring can be used in a very large number of applications, often relying on related services like geolocation, spatial operations (“close-to”, “within”) and notifications (sending mail). A practical product needs strong security, performance, scalability, support for many protocols (sensors and server-side), administration and flexibility of deployment options.
The AMTech M2MBridge is a node.js service that implements the AMTech IOT Protocol. The M2MBridge can run in a variety of devices; for our demos we currently have it running on a Raspberry Pi 3 using Ubuntu MATE.
The M2MBridge includes a core and an extensible plugin architecture, plus a growing set of plugins. The bridge is a common component of most real-life IOT applications connecting edge devices to the sensor and reasoning layers of the AMTech platform, providing intelligence at the edge, and supporting security, access control, auto-configuration and other key properties of real-life deployments.
Here is a sketch of the Bridge Functionality:
