--A random new thought-- I was looking through some example code for unrelated reasons, and I noted that some new stuff has the Power class / utility initialized near the normal M5 Begin. e.g.M5.Power.begin() (With some comments about that statement needing to be there.) I'm digging through Power's source files, but am somewhat unfamiliar with the class in general- so I'm not exactly certain of what properties or functions are available within it. (I know it's mostly in charge of interfacing with the I2C power controller on P21/P22- but not the specifics beyond that) Considering the Go Base has some different battery properties, AND tosses some extra items onto GPIO/I2C -- could this Connectivity issue perhaps be related to something needing to be set within the Power class, or within "M5.begin()" in general? Just a thought...maybe it'll spark an idea...
