I placed the Wisblock on a hill for a day and night to test as a go-between part of my mesh. When I left it, the connected 3000 mAH battery was fully charged and the solar panel was connected. For some reason, it shut itself down. I’m not certain if the battery was completely drained in just the over night’s time or if the board shut off by itself, but when I went to collect the board, it was on an “off” condition, ie not showing up on the phone app, all LEDs off. I was able to rouse it by hitting the reset button once. I don’t have the equipment to thoroughly test the battery.
Also, in attempting to upgrade the firmware to the 1.2.38 alpha, the file won’t copy to the board. When dragging the file onto the folder, I think the board boots Meshtastic before the new .uf2 is copied making it impossible to upgrade firmware.
