Higher than expected power consumption in idle mode #13

The same Low Power Home Network Weather Monitoring application on the CC1350 SensorTag and the CC1352 LPSTK shows very different power consumption levels measured with EnergyTrace when the node without screen is in idle mode.

Board	Idle mode (mA)
CC1352 LPSTK	1.864
CC1350 SensorTag	0.014

Configuration

Energia with EasyLink and Galaxia libraries
EnergyTrace with USB XDS110 probe

How to lower power consumption in idle mode?

The issue has been reported at the E2E forum under CCS/LPSTK-CC1352R: Large standby current consumption (1.7 mA) with LPSTK-CC1352R as sensor.
