From 33b42e8af9fd3aa0887ea7cc03616e5df353d5e4 Mon Sep 17 00:00:00 2001 From: Tom Fifield Date: Sun, 28 Apr 2024 12:47:19 +0800 Subject: [PATCH] shutdown after losing power - check power detection status before setting As described in meshtastic/firmware#3743 , some users were discovering that their devices unexpectedly powered down after setting "Shutdown on battery delay", despite their devices being connected to USB. This was due to the devices not correctly detecting that they were connected to USB. This can be resolved by altering the ADC_MULTIPLIER per existing instructions. This commit adds a note to encourage users to check the power status before enabling "Shutdown on battery delay". fixes meshtastic/firmware#3743 --- docs/configuration/radio/power.mdx | 3 +++ 1 file changed, 3 insertions(+) diff --git a/docs/configuration/radio/power.mdx b/docs/configuration/radio/power.mdx index 7621cfd9..7ddc1bcf 100644 --- a/docs/configuration/radio/power.mdx +++ b/docs/configuration/radio/power.mdx @@ -30,6 +30,9 @@ When activated, this feature disables Bluetooth, Serial, WiFi, and the device's Automatically shut down a device after a defined time period if power is lost. +Before setting this, ensure your board correctly detects when it is connected to external power (the "🔌" icon in the app).
