Thanks a lot! I think I will switch to Arduino at this point, it's probably more suitable for my application. I will give an update!

Cheers

M5.Power.setExtPower(true/false)

Hi Felix

Thank you so much for your response and the help!
I tried to change the code (I use UI Flow 1 and MicroPython), unfortunatelly there always occur errors… Is there maybe a library missing?

If I use the function: M5.Power.setExtPower(true/false) following error occurs:
Name ‘M5’ isn’t defined

If I use the function: power.setExtPower(true/false) following error occurs:
‘Axp2101’ object has no attribute ‘setExtPower’

Thanks!

Hi Guys

I have just received a new M5 Core2 with AXP2101 and have installed it in my setup, which has worked perfectly so far. In the setup (previously M5 Core2 with AXP192), I use the Mbus 5V output signal via step up to an external sensor and supply it with power. In the code I was able to supply the sensor with voltage or not with power.setBusPowerMode(). From other entries in the forum, I'm not sure whether this function is even intended for this, but it worked well in any case. I could only activate the sensor for the measurement to keep the power consumption low. With the new M5 Core2 model this no longer works and the sensor always has voltage. Is it because of the new AXP2101?
Is there a function how I can selectively activate or deactivate the Mbus 5V output?

Thank you very much
