Hello, tring to put mangoH yellow in ULPM. Steps: sent AT!POWERWAKE=2,36,1 AT!POWERMODE=3 on console i read: [ 794.449680] swimcu_pm_wusrc_config: check statep->gpio_pin_mask 0x1 [ 799.463291] MCU Protocol Command 0xC2 failed, retry=11 [ 799.467513] swimcu_pm_wusrc_config: failed to GPIO…

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

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

have you checked if there is interrupt on GPIO36? you can also see here for more information: [image] [WP7702] ULPM Led mangOH Yellow Hi, I use a Mangoh Yellow with a WP7702 chip Firmware + Legato: root@swi-mdm9x28-wp:/sys/bus# cm info Device: WP7702 IMEI: 352653090211…

Nope… i dont have an oscilloscope here… But… when i shake i see yellow light blink for a second… See attached video…

I think INT1 is connected to GPIO38 according to schematic: [image]

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…

Will try now with GPIO38… gimme some minutes…

Exact same behaviour with GPIO38. Led blinks… no boot.

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
