I have been testing an Argon to see how long it can run waking up every hour from deep sleep.
Was working great, had a LiPo battery attached. However, once battery (as reported by the argon) dropped under 3.3v (3.2 ish reported a few times, then stopped waking up. pulled the battery, plugged back in, it woke up, but then after deep sleep it won’t wake again
I have it plugged in and charging now, will see if it can wake from sleep while charging.
