Power Configuration
The power config options are: Charge Current, Power Saving, Shutdown after losing power, ADC Multiplier Override Wait Bluetooth Interval, Mesh Super Deep Sleep Timeout, Super Deep Sleep Interval, Light Sleep Interval and Minimum Wake Interval. Power config uses an admin message sending a Config.Power protobuf.
Power settings are advanced configuration, most users should choose a role under Device Config to manage power for their device and should never need to touch any of these settings.
Power Config Values
Charge Current
Tbeam 1.1 only setting
Sets the current of the battery charger using the AXP power chip on the Tbeam 1.1
Power Saving
If set, we are powered from a low-current source (i.e. solar), so even if it looks like we have power flowing in we should try to minimize power consumption as much as possible.
Shutdown after losing power
Automatically shut down a device after a defined time period if power is lost.
ADC Multiplier Override
Fixes issues on Heltec v2
Ratio of voltage divider for battery pin eg. 3.20 (R1=100k, R2=220k)
Overrides the ADC_MULTIPLIER defined in the firmware device variant file for battery voltage calculation.
Should be set to floating point value between 2 and 4
Wait Bluetooth Interval
How long wait before turning off BLE in no Bluetooth states
0 for default of 1 minute
Mesh Super Deep Sleep Timeout
While in Light Sleep if this value is exceeded we will lower into super deep sleep
or Super Deep Sleep Interval (default 1 year) or a button press
0 for default of two hours, MAXUINT for disabled
Super Deep Sleep Interval
While in Light Sleep if Mesh Super Deep Sleep Timeout Seconds is exceeded we will lower into super deep sleep or this value (default 1 year) or a button press
0 for default of one year
Light Sleep Interval
ESP32 Only Setting
In light sleep the CPU is suspended, LoRa radio is on, BLE is off an GPS is on
0 for default of five minutes
Minimum Wake Interval
While in light sleep when we receive packets on the LoRa radio we will wake and handle them and stay awake in no Bluetooth mode for this interval
0 for default of 10 seconds
