Hi, I am facing an issue my product contains Ble dfu update, I tested my code without enabling DFU and it runs fine ... but after enabling dfu and creating package... I update the device using dfutrg file gets uploaded successful and restart to new firmware version but after 7-8 seconds it restart itself multiple times then SHUTDOWN permanently, Also my code also faces issue on Sending data over ble, at first it sends data without any error and works correctly... Later on it start returning NRF_ERROR_NOT_FOUND from function -> sd_ble_gatts_hvx(conn_handle, &hvx_params);
