 I have a project use nrf52 to have a purpose below. 
 Maybe after some pairing process with smartphone. 
 The user can trigger the device(nrf52, may press a button). 
 The smartphone can have a notification that the button has been pressed without</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Fri, 15 Sep 2017 07:09:48 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/25182/notification-feature" /><item><title>RE: Notification feature</title><link>https://devzone.nordicsemi.com/thread/99205?ContentTypeID=1</link><pubDate>Fri, 15 Sep 2017 07:09:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:0053304c-5caa-4faa-a5dd-d4d564c7ce75</guid><dc:creator>Petter Myhre</dc:creator><description>&lt;p&gt;&lt;a href="http://www.nordicsemi.com/eng/Products/Nordic-mobile-Apps"&gt;Here&lt;/a&gt; is a list of our iOS apps, the source code of some of them can be found &lt;a href="https://github.com/NordicSemiconductor?utf8=%E2%9C%93&amp;amp;q=ios&amp;amp;type=&amp;amp;language="&gt;here&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Notification feature</title><link>https://devzone.nordicsemi.com/thread/99204?ContentTypeID=1</link><pubDate>Fri, 15 Sep 2017 01:20:23 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:525f3841-dae0-488a-892b-5e23bc92b774</guid><dc:creator>Jax</dc:creator><description>&lt;p&gt;Maybe corebluetooth can implement this feature.

Thanks for your quickly reply.
I understand about ble_app_uart example.
ble_app_uart need user open the app and connect to the device then send uart command.
We have already use this for the product.
But in iOS app, it&amp;#39;s not allow background service in iOS, so i can&amp;#39;t run a background service to accept uart command and make some alarm to user when user pressed HOME Key on Iphone.
Even after Android 8.0 policy, it alse kill the background server after app onPause.
How to implement this feature on BLE?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Notification feature</title><link>https://devzone.nordicsemi.com/thread/99202?ContentTypeID=1</link><pubDate>Thu, 14 Sep 2017 09:24:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9aa64180-d118-406c-993b-6cdaf61dff8f</guid><dc:creator>Petter Myhre</dc:creator><description>&lt;p&gt;There is no standard button profile. I recommend using &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.0.0/ble_sdk_app_nus_eval.html?cp=4_0_0_4_1_2_24"&gt;ble_app_uart&lt;/a&gt; as a starting point.&lt;/p&gt;
&lt;p&gt;Then instead of sending a notification when something is received on the UART you can send a notification when a button is pressed.&lt;/p&gt;
&lt;p&gt;The button implementation can be done in several ways, one way is by using the &lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.0.0/bsp_example.html?cp=4_0_0_4_5_4"&gt;bsp example&lt;/a&gt; as a starting point.&lt;/p&gt;
&lt;p&gt;What do you mean by without open app? Never open app? Or having the app running in the background?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
