 To send data to the Memfault cloud through a Bluetooth gateway, you must configure a project key using the :kconfig:option:`CONFIG_MEMFAULT_NCS_PROJECT_KEY` Kconfig option.
 You can find your project key in the project settings at `Memfault Dashboards`_.
-You also need to set the :kconfig:option:`CONFIG_MEMFAULT_NCS_DEVICE_ID` static Kconfig option for this sample
+Use the :kconfig:option:`CONFIG_MEMFAULT_NCS_DEVICE_ID`, to set the static device ID. For this sample, it is ``ncs-ble-testdevice`` by default.
