-You can also set the regulatory domain using an API call, the regulatory information can be passed using the ``nrf70_bm_init()`` API.

+The Scan and Radio test combo sample demonstrates how to switch between the Scan and Radio test operational modes, using different regulatory domains, at runtime.
+It does the following:
+
+ * Uses the regulatory domain ``WIFI_REG_DOMAIN``
+ * Initializes radio test mode and does continuous TX for 5 seconds, followed by a display of the statistics.
+ * Switches to scan mode and scans for the access points.
+ * Changes the regulatory domain to ``WIFI_REG_DOMAIN_2`` and repeats the above steps.
