Have you tried using the debugger to see what happens and if the application asserts?

I'm not sure what you mean by this.

Thank you for taking the time to answer. I tried to use app_button, which seems to conflict with the BSP button module. I ca n’t find how to close the BSP button alone. When I commented out buttons_leds_init (& erase_bonds); or err_code = bsp_init (BSP_INIT_LEDS | BSP_INIT_BUTTONS, bsp_event_handler) ; Changed to err_code = bsp_init (BSP_INIT_LEDS, bsp_event_handler); can work very well. And when I disconnect the power of nRF52 DK and connect it again, windows10 can't connect, repeatedly disconnect, the android device can click to connect again.
Try to modify sdk.config.h / BSP_BTN_BLE_ENABLED to 0, but it doesn't seem to work

(Sorry, my English is not good, I need an interpreter :D

Hi,

The example generates only one event per time a button is pressed. Which means that you would have to check if the button is still pressed if you want the cursor to keep moving. One way is by calling bsp_button_is_pressed() after a button pressed event is generated. You could then call mouse_movement_send() as long as bsp_button_is_pressed() returns true for that button. Just make sure that you don't do it in interrupt context as it might interfere with Softdevice operations. I suggest that you rather set a flag in interrupt context after the button has been pressed and then check the flag in a loop in main context. Probably not the most elegant solution, but it should work 🙂
