Beacon_CC2640_with_SensorController_HDC1080

Sensor beacon with the HDC1080 temperature and humidity sensor. Based on the Ti CC2640R2F SoC.

The project used:

• Micro Eddystone Beacon
• HDC1080-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.

How to change TX output power.

• To change TX output power, you need to change the TX_POWER constant in the micro_eddystone_beacon.c file.
• Possible values are defined in the urfc.h file. Maximum value = TX_POWER_5_DBM (5 dbm). Minimum value = TX_POWER_MINUS_21_DBM (-21 dbm).
