Beacon_CC2640_with_SensorController_HTU21D

Sensor beacon with the HTU21D temperature and humidity sensor. Based on the Ti CC2640R2F SoC.

The project used:

• Micro Eddystone Beacon
• HTU21D-sensor-controller

Software Tools:

• Sensor Controller Studio v2.7.0.155
• Code Composer Studio v10.1.0
• XDCtools v3.51.03.28_core
• simplelink_cc2640r2_sdk_4_20_00_04

Temperature and humidity advertising:

• Eddystone TLM frame is used for temperature advertising. This makes it possible to use applications such as Beacon Scaner or similar for viewing.
• Fot humidity advertising, TLM format expanded, additional two bytes are added(bytes offset 14,15). Humidity, measured by the beacon, is expressed in a unsigned 8.8 fixed-point notation. Range of the humidity 0-100%. To view humidity, you need an application that can work with the extended TLM format.
