At the moment I am using the following code to save energy.
screenlight turn off, not the backlight. axp.setLcdBrightness(0)
wifi turn off wlan = network.WLAN(network.STA_IF) wlan.active(False)
but still the total curent use is 150-200mA
If an I2C error occurs, I use M5Burner and then burn new software on it. the I2C error code only appears if you have the M5 stick in USB mode. If you have the M5stick in App mode, it does not happen. probably it is in the COM port that is active.
