NRF52 hard fault when calling xQueueSend for another task while the BLE connection is activehttps://devzone.nordicsemi.com/f/nordic-q-a/104565/nrf52-hard-fault-when-calling-xqueuesend-for-another-task-while-the-ble-connection-is-activeHi, I&#39;m developing an application which uses BLE softdevices and 2 other created tasks. The problem is that when I call xQueueSend to send an event to one task, I get a hard fault error: &lt;error&gt; hardfault: HARD FAULT at 0x000482BC &lt;error&gt; hardfaulten-USTelligent Community 13Thu, 12 Oct 2023 00:56:08 GMTRE: NRF52 hard fault when calling xQueueSend for another task while the BLE connection is activehttps://devzone.nordicsemi.com/thread/449938?ContentTypeID=1Thu, 12 Oct 2023 00:56:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:176c5085-537a-4189-aaf4-f17f6a23e206EAkeila<p>Thanks a lot Vidar.

The stack size is harcoded through the&nbsp;NRF_BLE_FREERTOS_SDH_TASK_STACK define in /components/softdevice/common/nrf_sdh_freertos.c</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
