Power management (nRF52)

BOOTLOADER · POWER SOURCE · BOOT REASON · BOOT VOLTAGE

Five read commands for nRF52 boards. The official documentation lists them under Bridge, but in the firmware they depend on the platform: NRF52_PLATFORM and NRF52_POWER_MANAGEMENT (CommonCLI.cpp r.884–928).

[!NOTE] Source. This page was verified against the firmware itself: MeshCore v1.16.0, commit 03b6ef4, 28 July 2026 — files src/helpers/CommonCLI.cpp, src/helpers/NRF52Board.cpp, variants/sensecap_solar/platformio.ini, and the official docs/cli_commands.md. Line numbers refer to this commit and can be reproduced with tools/cli-commands.py.

Overview

The markers in the Role column are explained in the CLI reference. An empty cell means: works on repeater, room server and sensor.

Command	Role	Default	Serial only	Source
get bootloader.ver	build flag	—		CommonCLI.cpp r.884
get pwrmgt.support	build flag	—		CommonCLI.cpp r.903
get pwrmgt.source	build flag	—		CommonCLI.cpp r.909
get pwrmgt.bootreason	build flag	—		CommonCLI.cpp r.915
get pwrmgt.bootmv	build flag	—		CommonCLI.cpp r.923

Commands

bootloader.ver

Bootloader version, or > unknown. On other platforms: ERROR: unsupported.

Example (ESP32):

get bootloader.ver
  -> ERROR: unsupported

pwrmgt.support

> supported if the build sets NRF52_POWER_MANAGEMENT, such as the SenseCap Solar (variants/sensecap_solar/platformio.ini r.13), otherwise > unsupported.

Example (SenseCap Solar):

get pwrmgt.support
  -> > supported

pwrmgt.source

> external or > battery. Without power management: ERROR: Power management not supported.

Example:

get pwrmgt.source
  -> > battery

pwrmgt.bootreason

Reason for the last reset and the last shutdown, as text (NRF52Board.cpp r.69 onwards).

Example (board without power management):

get pwrmgt.bootreason
  -> ERROR: Power management not supported

With power management the form is > Reset: <reason>; Shutdown: <reason>, for example with reset reason Reset Pin.

pwrmgt.bootmv

Voltage at start-up, as > <n> mV.

Example (board without power management):

get pwrmgt.bootmv
  -> ERROR: Power management not supported
