Our first video is a small overview of the components.

Iphone connected with audio jack to our breadboard prototype (pcb prototype comming next week or so) 

The breadboard prototype has a wire with IR transceiver positioned atop the Kamstrup heating meter ( see white ribbon cable and improvised supporting "op" box)

The app starts in device list mode and we select the demo device. We see that the PIC mcu interprets the audio via the red debug leds on the breadboard.

We then via same red leds see that the Kamstrup answers and in the end we see the refreshed view on the iphone app.
