Body:
Board / hardware
LilyGo T-Echo (nRF52840 + SX1262, e-ink display)
Firmware
MeshCore Companion BLE firmware, v1.16.0 (official release, 2026-06-06)
Description
When triggering hibernate via the on-device menu (double-press bottom button → select Hibernate), the e-ink display shows "hibernating..." — but this text remains on screen indefinitely rather than the display going blank, refreshing to a static screen, or otherwise indicating the device has reached a powered-down state.
The Bluetooth LED is off during this state (so the LED issue previously fixed for T-Echo in #957 does not appear to be present here), but the persistently displayed "hibernating..." text suggests the device may not be reaching a true system-off / deep sleep state on the MCU and/or e-ink controller — it looks more like the device is paused mid-transition rather than fully powered down.
Steps to reproduce
Flash T-Echo with Companion BLE firmware v1.16.0
From the device menu, double-press the bottom button to open the menu
Select "Hibernate"
Observe: display shows "hibernating..." and stays in this state indefinitely (observed for several hours)
Expected behavior
After triggering hibernate, I would expect the device to reach a true low-power/system-off state, with the e-ink display either going blank or retaining its last static image without an active "hibernating..." message implying an in-progress or stuck transition.
Actual behavior
Display permanently shows "hibernating..."
Device can only be woken by a single press of the top (reset) button, which triggers a full reboot rather than a quick resume — consistent with the device not being in a resumable sleep state
