&lt;p&gt;The error message indicates that the MAC address you&amp;#39;re trying to program is invalid.&lt;/p&gt;
&lt;p&gt;Please ensure that the MAC address you&amp;#39;re trying to program is a valid unicast MAC address. For example, the MAC address&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code dir="ltr"&gt;F0:CE:36:00:00:4A&lt;/code&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;can be programmed to MAC[0] by using the Wi-Fi Radio test command&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;code dir="ltr"&gt;wifi_radio_ficr_prog otp_write_params 0x120 0x0036CEF0  0x4A00&lt;/code&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;as shown in this &lt;a href="https://docs.nordicsemi.com/bundle/nan_043/page/APP/nan_043/mac_address_programming.html#ariaid-title1"&gt;Program the MAC address&lt;/a&gt;&amp;nbsp;doc.&lt;/p&gt;
&lt;p&gt;&lt;span&gt;If you&amp;#39;re unsure about the validity of your MAC address, you may want to consult with your network administrator or refer to the IEEE guidelines for MAC address assignments.&lt;/span&gt;&lt;/p&gt;
