 my chip is NRF52832 (512k FLASH + 64k RAM). 
 I want to triggle ESB send process by PPI + TIMER ,but i can&amp;#39;t find the function like esb_task_address_get()，but i found some info in the datasheet: 
 
 so i write like this: 
 
 but its seems not work</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 06 Jun 2019 10:29:27 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/47946/how-could-i-start-esb-tx-by-using-ppi-timer" /><item><title>RE: how could i start ESB tx by using PPI + TIMER</title><link>https://devzone.nordicsemi.com/thread/191302?ContentTypeID=1</link><pubDate>Thu, 06 Jun 2019 10:29:27 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:2a79d874-af8e-472b-bea2-7802cebe1f18</guid><dc:creator>zyj</dc:creator><description>&lt;p&gt;Thank you very much! i have solve the problems.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: how could i start ESB tx by using PPI + TIMER</title><link>https://devzone.nordicsemi.com/thread/190448?ContentTypeID=1</link><pubDate>Mon, 03 Jun 2019 09:11:05 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:6c23d569-b886-47a0-8829-fb2c472e49f8</guid><dc:creator>H&amp;#229;kon Alseth</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;PPI task and events can only be used on a peripheral level. nrf_esb is a higher level protocol, which sets up buffers and other protocol related logic, so PPI cannot be hooked up against the function to start the radio in a certain ESB mode.&lt;/p&gt;
&lt;p&gt;You will have to involve the CPU in order to push a packet to the nrf_esb FIFO.&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>
