I have the following code to update wallpaper with custom base64 encoded image. I am confident this is correct, but I keep getting the error "Problem sending command, prior command may be pending, or device may not be capable."
I can't seem to find any indication what would cause this. Any thoughts or ideas would be appreciated.
