Paper S3 wake on IMU?
-
The Paper S3 has a BMI 270 that should let it wake from sleep when moved. Has anyone figured out how to do this from deep sleep or light sleep? Me, ChatGPT, and the M5Stack chat tool have not been able to figure it out! We get it to sleep but cannot wake it from the IMU

Hello @alexxai
short answer: not possible
long answer: the IMU interrupt line (INT1) is not connected to any ESP32S3 GPIO and therefore it cannot wake up ESP32S3 from deep or light sleep. See schematics here.
That said IMU interrupt line is connected to the power on / off logic (IC PMS150 via E_TRIG) so it should be able to turn on M5PaperS3.

@felmue Thanks so much for your reply and clear info - and sorry for my delay in replying, I didn't get an email alert that there was a response.
Can you elaborate on the PMS150 idea - basically I should power off the device fully and then use the IMU int to power it up again when movement is sensed?
On the store page for the device it mentions "wake-up by lifting", which is why I thought I could kick it out of light or deep sleep with IMU movement. But I guess this is what they mean by that?
