No battery to supply the S6SAE101A00SA1002
I am testing a S6SAE101A00SA1002 evaluation kit, and I need to test the Bluetooth communication in a dark environment, so the solar cell cannot supply the board. Since there is a VBATT input for an optional coin cell battery, I connected a CR2032 battery to it, but I cannot make the board work when it is supplied both with battery and battery+solar cell. The only way to supply the board seems to be the solar cell, although the S6AE101A datasheet says it is possible to connect a battery alongside the solar cell.
How can I supply the board with a battery?
