&lt;pre&gt;&lt;code&gt;typedef struct
{
  uint16_t conn_handle;                   /**&amp;lt; Connection Handle (only applicable for get) */
  uint8_t ch_map[5];                      /**&amp;lt; Channel Map (37-bit). */
} ble_gap_opt_ch_map_t;
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Please take a look &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v2.0.0/structble__gap__opt__ch__map__t.html?cp=2_3_0_1_0_3_0_47"&gt;here&lt;/a&gt; for details.&lt;/p&gt;
&lt;p&gt;There is also Direct Test Mode (DTM) profile but I have never tried it. If you have question on fixed frequency, I suggest reading this page: &lt;a href="http://large.stanford.edu/courses/2012/ph250/roth1/"&gt;large.stanford.edu/.../&lt;/a&gt; on Frequency Hopping&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
