The SensorTag kit connects six (6) sensors to TI’s CC2541 Wireless MCU that features Bluetooth Low-Energy (BLE) connectivity. The sensors are temperature, humidity, pressure, accelerometer, gyroscope and magnetometer. It seems to me that connecting some of these to a BeagleBone Black could be pretty handy for collecting environmental data, so I decided to try it out. (disclosure: I work on BeagleBone Black and for TI, so I figure my employers wouldn’t mind me doing this on company time either.)
It turns out grabbing data from the SensorTag using a Bluetooth dongle and Node.JS on BeagleBone Black was rather easy. Working with the MQTT tools still remains a bit of a challenge for me.
