You can build your own wireless colour sensor in 5 seconds using Blebricks: just stack the BLE-B, the BLE-RPS and the BLE-RGB with the help of a horizontal mounting base.
OTA Firmware Update
The Over The Air Firmware Update feature allows you to always keep your BLE-B up-to-date, wirelessly.
What you need to do is:
Near Field Communication
Our BLE-B can emulate a Near Field Communication tag that you can read or write using your smartphone.
Apps such as “NFC Tools” allow you to write different information on the tag such as text, URL links, global coordinates, and even instructions for triggering a call or a SMS on the reading smartphone.
