 I am developing a ble scanner using RADIO Peripheral. 
 I have 2 questions to ask 
 1.When is the END event triggered?, How does the hareware know the packet is received completely? 
 2.Is there any example for reference.

[quote user=""]1.When is the END event triggered?, How does the hareware know the packet is received completely?[/quote]
&lt;p&gt;The hardware listens for a packet matching its expected format, meaning:&lt;/p&gt;
&lt;p&gt;preamble, address, content, crc.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;When it receives a pattern it expects, with a corresponding correct checksum, it will fire the _END event. You can also read the RADIO peripheral chapter in the PS for more information.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
[quote user=""]2.Is there any example for reference.[/quote]
&lt;p&gt;No, unfortunately not.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
&lt;p&gt;Håkon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
