Kona Currents, LLC offers a unique Remote Education and IoT processing app for creation, collection, processing, search, and messaging of optical visual markers we call Semantic Marker (R). An innovative text and optical search engine is included, along with an API for processing optical labels, barcodes and two-dimensional codes. These optical image and data files are downloadable for internal and external use. This app interacts through published API's with Cloud Computing services. The app will communicate via MQTT messaging among a suite of IoT devices, as well as using Bluetooth Low Energy (BLE) directly to devices, which is especially useful to set credentials such as WIFI passwords for the IoT devices (ie. ESP 32 devices). See SemanticMarker.org for more on the abilities use.
