My Bad... I like to clear some mistake of my post.
Excuse for my bad english. What I'm saying is when I use python code like "wifi.connect(SSID, PW)". It will fail , unless reflash configurate setting with M5Burner to the same SSID and Password setting as code.
vlw font work perfectly when I change the code from "Buf=M5.Lcd.newCanvas(130,50,1,True)" to "Buf=M5.Lcd.newCanvas(130,50,16,True)". I think this might support 16bit sprite only.
That only happen when I use the second UART in M5StickC (although this could be done in UIFLOW1.0).
