Before anything can be sent to the ‘backend’ messaging software and into Bluemix, we need to handle a series of inputs. This week I took delivery of some hardware from our friends at Freescale. The Telemetry process and equipment provided they kindly sent me for testing their Freescale IOT unit. This unit is self-contained and as per the architecture diagram below, receives, handles and transmits feed from various sources, either wirelessly or by direct connection.

The Freescale LS1021A – Internet of Things unit.

Preliminary testing: The unit in my garage hooked up to a 12v car battery, with both cameras, heartrate monitor, GPS system all connected. Using my laptop and mobile, I could see the data graphically and numerically having been passed to and processed by MQTT and Bluemix.
The data could be seen on-line via the bluemix cloud server or picked up on my mobile via 4G. We are setup as ‘Vehicle 6/G’.

The system also has a graphical display, where live feed output from the camera is shown, along with everything else being recorded. Currently we are looking to add to the graphical display data from GPS location to cover our Altitude in the mountains and also using a Bluetooth sensor tag to read and record engine temperature. As we are already reading heartrate via Bluetooth, we should be able to hook into this feed in the car.

The next day I set the system up in my Jaguar and drove to work, far more modern that the Riley and also sporting a 12v supply. When I got to the office I had a look at the data that had been sent through.

Must not forget the ‘other’ piece of hardware, the Riley. This week we were out testing the car for the first time. With only two weeks to go before the tour start, we have a number of teething problems to overcome as we go through ‘shakedown’ testing… Quite literally which bolts fall of and from where!

The joy of working a project like this is very much experimental and trying different scenarios and solutions to gain success. Mechanical Engineering and Software Engineering, no difference really, plenty of testing, reworking and testing again. It is the very nature of Development.

The 1933 Riley, almost tour ready!
