My mc-Module 120 reports 2660 for Device.BatteryVoltage, yet when I use a digital multimeter on VDD and GND pins I read 2.96V. My multimeter seems to read 0.3V higher than the device.
Does anyone experience similar behavior with battery voltage?
Also (done with a different battery), does calling Device.BatteryVoltage substantially drain the battery? I ran a mc-Module 120 for only 12 days before the 3V CR2032 battery died. Granted, the battery may have been used for several firmware updates and is several months old, but it reported 2.865V 6 days ago. This mc-Module 120 reported temperature every 5 minutes and Device.BatteryVoltage every 1 day.
