This week, I mostly worked with my team on selecting the right components, eg. the microphone, the battery, the altimeter, the BLE chip… Thomas did a great schematic to sum it up. We are now focusing on the PCB design to be able to send the PCB to production as soon as possible.
This weekend, I worked on my nRF51822 evaluation kit. I was able to flash a proximity app example. I can connect to it using my Android smartphone (Samsung Galaxy SIII / Android 4.3) and the app nRF Toolbox from the Google Play Store. I can light up a LED on the board from the phone or ring the phone from the board, all using Bluetooth Low Energy. It works really great!
I also started to work on the Android app. More to come very soon!
