 We have designed board with nrf52840 and nrf21540. Right now I am finding out that nrf21540 is actually not compatible with BLE?? Our main case is ESB communication, so can nrf21540 work with that? We are also using DFU over BLE, so that would be</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 08 Mar 2023 08:25:14 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/75386/nrf21540-with-esb" /><item><title>RE: nrf21540 with ESB</title><link>https://devzone.nordicsemi.com/thread/414019?ContentTypeID=1</link><pubDate>Wed, 08 Mar 2023 08:25:14 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:37d4e02c-327d-4de5-9af7-e9dfaedcabf0</guid><dc:creator>Einar Thorsrud</dc:creator><description>&lt;p&gt;No, unfortunately not.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrf21540 with ESB</title><link>https://devzone.nordicsemi.com/thread/413967?ContentTypeID=1</link><pubDate>Tue, 07 Mar 2023 22:05:51 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:3a840366-99a2-4a82-a10d-871c4d5e8370</guid><dc:creator>enukic</dc:creator><description>&lt;p&gt;Thank you Einar.&lt;br /&gt;And what about nRF5 SDK?&amp;nbsp;Would it work at all?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrf21540 with ESB</title><link>https://devzone.nordicsemi.com/thread/413750?ContentTypeID=1</link><pubDate>Tue, 07 Mar 2023 09:34:16 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:92e789ae-aff3-4263-96e8-bdcd37443782</guid><dc:creator>Einar Thorsrud</dc:creator><description>&lt;p&gt;Hi Emir,&lt;/p&gt;
&lt;p&gt;Yes, for the most part it is fixed, though &lt;a href="https://infocenter.nordicsemi.com/topic/ps_nrf21540/chapters/device_control/doc/state_transition_timing.html"&gt;state transition timings&lt;/a&gt; (particularly from power-down are a bit long). I recommend you use nRF Connect SDK 2.3.0 or later, as that has the most recent fixes, including a fix that prevented Tx power from being correctly configured in nRF Connect SDK 2.2.0 and older.&lt;/p&gt;
&lt;p&gt;Regarding HW you should use revision 2 (build code G).&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrf21540 with ESB</title><link>https://devzone.nordicsemi.com/thread/413709?ContentTypeID=1</link><pubDate>Tue, 07 Mar 2023 07:24:31 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d49d1afe-3a52-4388-a8ed-78023905f9fe</guid><dc:creator>enukic</dc:creator><description>&lt;p&gt;Hi &lt;a href="https://devzone.nordicsemi.com/members/einar-jenssen"&gt;Einar Jenssen&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;could you please check if this issue is fixed in a more recent revision? If so, which revision is that?&lt;br /&gt;&lt;br /&gt;Thanks&lt;/p&gt;

I don&amp;#39;t understand what are you trying to do here? My question is related mainly to ESB support not BLE, which does not have clear answer on devzone. Also I am not trying to find out WHEN nrf21540 will be supported but rather HOW I can deal with current hardware.&lt;/p&gt;
&lt;p&gt;If you have some useful input on of these, please share it.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrf21540 with ESB</title><link>https://devzone.nordicsemi.com/thread/310694?ContentTypeID=1</link><pubDate>Thu, 20 May 2021 10:36:35 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:957fb117-9b88-4971-9cc5-7505857364f1</guid><dc:creator>awneil</dc:creator><description>&lt;p&gt;OK.&lt;/p&gt;

&lt;p&gt;Yes, that is certainly what it says:&lt;/p&gt;
