 I am new to nRF5x BLE devices. 
 I need to create a project and would like you to help me out. 
 I need to connect two nRF51822 devices. If one of the devices goes away from the proximity (5m) one of it beeps with a buzzer.

I just received my BK and DK. Will start developing soon.
I have another question, What is the best way to connect these two devices and performing this task(Bonding, beacon advertisement etc)?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF51822 to nRF51822 proximity buzzer help</title><link>https://devzone.nordicsemi.com/thread/56015?ContentTypeID=1</link><pubDate>Thu, 23 Jun 2016 10:32:43 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d5146864-fdc7-4a16-a3c9-2af94b3bb25c</guid><dc:creator>&amp;#216;yvind Karlsen</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;This is possible, the simplest way to implement this would be using the received signal strength indication (RSSI) and calibrating this for the real life usage scenario. This is similar to what you suggest in 3.2.&lt;/p&gt;
&lt;p&gt;I do not recommend using the arudino IDE for this, instead have a look at our &lt;a href="https://devzone.nordicsemi.com/tutorials/2/"&gt;getting started tutorials&lt;/a&gt; using the Keil IDE.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
