Sensortag

BTLE TI Sensortag snapcraft yaml file to buils a sensortag snap

Build and run the snap

Clone or dowload the repo to a Linux device running snapcraft 2.x and build the snap with snapcraft. Run the snap installing on a snapd capable system. More info at http://snapcraft.io/create/

Usage and examples

Use hcitool lescan to get the sensortag address:

~$ sudo hcitool lescan
LE Scan ...
A0:E6:F8:B6:E7:86 (unknown)
A0:E6:F8:B6:E7:86 CC2650 SensorTag

Connect the interfaces so sensortag can use the btle stack:

sudo snap connect mysensortag:bluetooth-control core:bluetooth-control

Call sensortag with --all to get reading from all the sensors and -n 2 to get two readings, do specify the address of your sensortag device.

~$ mysensortag.sensortag --all -n 1 A0:E6:F8:B6:E7:86
Connecting to A0:E6:F8:B6:E7:86

This snap works with the TI CC2650 multi-standard SensorTag.

  • Temp: Ambient and Object temperature (Cs)
  • Humidity: Ambient temperature (Cs) and relative humidity (%)
  • Barometer: Temperature (Cs) and Air Pressure (hPa)
  • Accelerometer: X,Y,Z axis with a default period for the data is one second. (Gs)
  • Magnetometer: Strength of a magnetic field in the three axis (uT)
  • Gyroscope: Rotational motion (degrees/second)
  • Light: Ambient Light (Lux)

Sensortags with older firmware versions might not work properly with --all.
