Hi there,
Yes it’s confirmed that the Sleep does NOT work after updating to 2.9.2. the Battery does read and track well, the
notice the 0 in the lower left corner of display shows usb cable PLUGGED in charging “0”
which is great, but not helpful if the SLeep function that worked in all previous BSP’s
does NOT work anymore.
Try any of the TAP to wake demo’s on here.
the MCU won’t stay asleep until tap’d.
So for me BSP 2.9.2 is Broken
I combined the test and the Battery read . One should load with 2.9.1 BSP , Sleep works
(3button presses)
load BSP 2.9.2 battery read works , but 3 button presses (User Button) Xiao won’t stay sleeping. Until double tap “wakeUp”
