RAK4631 Solar Charging / wake up from extended cloudy days

using a RAK 4631 with a RAK solar enclosure and running Meshcore 1.11 in repeater mode. The repeater’s battery was slowly depleted due to short days and overcast conditions to the point where the repeater went offline (lasted around 30 days). We finally had a few sunny days to absorb a recharge and the repeater stayed offline.

After climbing on the roof to retrieve the system and connecting it to a charging source it still didn’t power up. I had to cycle the switch to get it to wake up. It appeared to have ~33% battery upon initial power up.

Is there a setting that anyone knows about that allows it to power back up on it’s own after it sees some battery level?

Hi @megawatt ,

As for RAK4631 in baseboard, there is no protection circuit that stops the MCU. On the hardware side, there nothing that stops it in booting up. On the software side, Meshcore can provide clarify if they are some kind off undervoltage lockup configured or anything like that in the FW. Because based on your description, you have to fully remove the battery then put it back again.
