https://devzone.nordicsemi.com/f/nordic-q-a/69331/i-d-like-to-cut-off-the-bluetooth-connection-and-stop-advertisingHello I&#39;m using nrf52832 and sdk v17.0 and I&#39;m testing in the example of ble_app_uart. I&#39;m creating a feature that Bluetooth disconnecting and then stops advertising. I use &#39;sd_ble_gap_disconnect&#39; and &#39;adverting_stop&#39; to do these two things.

If the handler runs at a priority above 4, you will not be allowed to call SD APIs. In that case, try setting a flag in the handler and call the functions in main loop whenever the flag is set.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
