 We are developing a proprietary application for Android tablets using the Android-BLE-Library and have been experiencing issues with scanning after a long period (&amp;gt; 12 hours) of successful operation. 
 Here is a brief overview of the problem</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 13 May 2020 09:19:40 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/61119/android-ble-library-scanner-stops-scanning-after-many-hours" /><item><title>RE: Android-BLE-Library scanner stops scanning after many hours</title><link>https://devzone.nordicsemi.com/thread/249633?ContentTypeID=1</link><pubDate>Wed, 13 May 2020 09:19:40 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:a02ceecf-7863-4783-b735-fa37ec6e9e25</guid><dc:creator>Simonr</dc:creator><description>&lt;p&gt;Hi Ken&lt;/p&gt;
&lt;p&gt;Sorry about the delayed reply. I&amp;#39;ve talked to one of our Android experts regarding your issue, and here are some notes we have:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;First, we assume you&amp;#39;re using the &lt;a href="https://github.com/NordicSemiconductor/Android-Scanner-Compat-Library"&gt;Android Scanner&amp;nbsp;Compat Library&lt;/a&gt;&amp;nbsp;for the scanning purposes, as the &amp;quot;regular&amp;quot; Android BLE Library doesn&amp;#39;t support scanning.&lt;/li&gt;
&lt;li&gt;The scanner compat library for Android just forwards requests to the native API, so if you&amp;#39;re seeing issues, this might be the Bluetooth stack that&amp;#39;s having issues.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;To your questions:&lt;/p&gt;
&lt;p&gt;a) We&amp;#39;re not familiar with this issue I&amp;#39;m afraid, as we generally do tests for ~1 minute, not 24 hours.&lt;/p&gt;
&lt;p&gt;b) We do not have a commercial version of this library I&amp;#39;m afraid.&lt;/p&gt;
&lt;p&gt;c) As stated above, we assume this might be the BLE stack&amp;#39;s interoperation with the library that&amp;#39;s causing this issue.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Simon&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Android-BLE-Library scanner stops scanning after many hours</title><link>https://devzone.nordicsemi.com/thread/248938?ContentTypeID=1</link><pubDate>Fri, 08 May 2020 12:18:50 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d302e698-fc7b-40cf-8089-e1fa3b0628a7</guid><dc:creator>Simonr</dc:creator><description>&lt;p&gt;Hi Ken&lt;/p&gt;
&lt;p&gt;I&amp;#39;ve asked our Android BLE library expert to take a look at this case, so please be patient and know that a reply is on its way.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
