I would like to control GPIO25 with WP76xx module. I am trying sample code as below URL . [image] mangOH/mangOH 524d0f9feae2ab6bb92bab03c346b08c4439f38f/samples/tutorials/hardwareInterfaces/gpio/Cf3GpioControl Primary mangOH git repository. Contribute to mangOH/mangOH development by c…

It seems you need to “app start” your application. You can also try this sample [image] legatoproject/legato-af master/apps/sample/gpioCf3Demo Legato Application Framework. Contribute to legatoproject/legato-af development by creating an account on GitHub.

Thanks for your reply. I tried sample and confirmed start. Apr 5 02:36:04 swi-mdm9x28-wp user.info Legato: INFO | gpioCf3Demo[12467]/gpioCf3PinComponent T=main | gpioCf3Pin.c _gpioCf3PinComponent_COMPONENT_INIT() 135 | This is sample gpioctl Legato CF3 GPIO app by using le_gpio.api But code sto…

You can debug the app and see where makes this: gpioSysfsUtils.c gpioSysfs_SetChangeCallback() 596 | Only one change handler can be registered

You might also try the application here [image] Is there a sample app using gpio pin? mangOH Yellow I used the sysfs command, but I don’t know what api can be used to produce the desired output on the digital pin through which function call can be used.
