If i use AT!POWERWAKE=2,38,5 devices shutsdown but never awake… it become blind to GPIO38… shaking have no effect at all. Also leds stop blinking. Only way to wakeup is poweron with button . … almost desperate… … i cant see any resolution to issue QTI9X06-192 … nor workaround i can use… g. ---

Did you compile the bmi160 driver? You might also try original gpio36 test and see if it blinks ---

Have you tried “leaf search”? ---

Using latest mangoH yellow firmware from here: [https://mangoh.io/mangoh-yellow-resources](https://mangoh.io/mangoh-yellow-resources) Mangoh Yellow latest firmware is a little bit older than Rel. 14.1 > root@swi-mdm9x28-wp:~# cm info > Device: WP7702 > IMEI: 352653090386178 > IMEISV: 5 > FSN: 4L033685021210 > Firmware Version: SWI9X06Y\_02.35.02.00 5208b3 jenkins 2020/06/10 00:30:12 > Bootloader Version: SWI9X06Y\_02.35.02.00 5208b3 jenkins 2020/06/10 00:30:12 > MCU Version: 002.014 > PRI Part Number (PN): 9909138 > PRI Revision: 001.010 > Carrier PRI Name: SIERRA > Carrier PRI Revision: 001.036\_001 > SKU: 1104405 > Last Reset Cause: Reset, User Requested > Resets Count: Expected: 151 Unexpected: 0 Anyway… no changes.

Jeremy can you share the solution that worked for you? Regards Gianmaria ---

Probably you need to solder a wire to gpio36 or gpip38 to change the state and see if this can wake up the module in ulpm mode This can isolate the problem in bmi160 ---

Maybe i have to review the driver for BMI160 and see if INT1 is enabled…and linked to some events (es. significat motion). And see if registers are set in the right way to keep config during ULPM. I’m sure INT1 is physically linked to GPIO38… we review the schematics a lot of times. Gian ---

from the schematic, GPIO36 is connecting to the light sensor’s interrupt. And gpio38 is connecting to the BM160’s interrupt. Not quite sure whether you shake the board is really related to the BMI160 as previously you are using GPIO36 for wake up pin… ---

Hi, We have abandoned the wake-up on GPIO. We now use wake up on ADC2 which serves us as wake up on GPIO: 0 or 1 Best Regards, Jeremy ---

Thanks anyway. I found my problem is in driver. On default .ko INT1 is not enabled. [Previous page](https://mangoh.discourse.group/t/mangoh-yellow-ulpm/9977.md?page=1)
