didn’t you should trigger GPIO36 to wake up the module? ---

I guess the GPIO36 is connected to the INT1 of the BMI160. No? ---

Nope… i dont have an oscilloscope here… But… when i shake i see yellow light blink for a second… See attached video… [https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/5/570cdb29015192207218e58ac89515cfd39acb25.mp4](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/5/570cdb29015192207218e58ac89515cfd39acb25.mp4) ---

I think INT1 is connected to GPIO38 according to schematic: ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/3/324cc5ecaec0563736d842d42cdc1e310104a1f3.png) ---

Yes… got same problem… but i need both interrupts active. I use gpio21 in software to handle movement alerts… and also i need INT1 to wake up when in ULPM. …big problem… ---

how about trying the timeout value in AT!POWERWAKE? Not sure if you need to trigger POWER\_ON\_N when module in ULPM mode, you can make some test on this pin ---

Hi, It looks like you are using WP7702 firmware version 12. ULPM cannot be enabled with GPIO36/38. I had the same problem.
