Seeed Xiao nrf - Brownout condition

[G0BMH-HA]

I may be mistaken, but I was under the impression from details given regarding firmware v1.12, that a repeater suffering from loss of power due to a low battery should now be able to recover without a physical reset.

I have a couple of solar nodes that I was hoping I would no longer have to visit in order to get them back on air once the battery had recharged enough to reboot i.e. had reached at least 3.3v. Testing has unfortunately proved this to be untrue.

Is the documentation incorrect on this? Or is it just my understanding that is flawed?

Thanks.

Only the first phase is implemented (checking voltage on boot), no runtime monitoring yet. So we need to wait for phase 2 to get this sorted out

Right.

It might be worth making this clearer in the documentation as it appears to read that the feature is fully implemented.

Voltage Wake (LPCOMP + VBUS)

Configures the nRF52's Low Power Comparator (LPCOMP) before entering SYSTEMOFF
Enables USB VBUS detection so external power can wake the device
Device automatically wakes when battery voltage rises above recovery threshold or when VBUS is detected

"Board | Implemented | LPCOMP wake | VBUS wake
Seeed Studio XIAO nRF52840 (xiao_nrf52) | Yes | Yes | Yes "

Appears to indicate that the device in question is supported.
