4 Test and Verification

To allow for accurate comparison between Standby and Sensor Controller system solutions, the HDC2010 sampling code with periodic RF transmission was implemented also on the main Arm Cortex-M4F MCU instead, while the SCE is left unused. Using the same duty-cycle of 60 seconds and same RF parameters and packet length, also the Duty-cycling approach as in the TIDA-00484 reference design was added.
