I have a 20A smart socket (BL602/BL0937) I managed to load - BL602 UART Flash - OpenBL602_1.17.759.bin from https://github.com/openshwprojects/OpenBK7231T_App/releases. Unfortunately after assembling it, nothing works, it doesn't even turn on. The button doesn't work. Is there any easy way to configure the pins?
