IoT/M2M gateways are critical to make robust Iot solutions. They must react locally even if the network is down, must ensure security functions are handled, be responsive and minimize traffic. Programming these gateways can become quite challenging. Reactive Blocks combines simplicity of visual programming with the flexibility of manual coding and advanced error-free code generation to build robust applications
