 So we don&amp;#39;t need ATT,GATT,GAP,SDP,SMP and all high-level things. 
 As I can see from nrf52840 specification, we could set TX POWER, Mode and data rate, frequency</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 13 Feb 2020 10:15:24 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/57761/proprietary-low-level-development" /><item><title>RE: Proprietary low-level development.</title><link>https://devzone.nordicsemi.com/thread/234147?ContentTypeID=1</link><pubDate>Thu, 13 Feb 2020 10:15:24 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:bf7f92a0-3c72-4704-bed4-373949a8fe35</guid><dc:creator>haakonsh</dc:creator><description>[quote user=""] So, do it correct to say - all frequency hoping and TX Power adjustments is done in BLE stack by software means ???&amp;nbsp;[/quote]
&lt;p&gt;&amp;nbsp;Yes.&amp;nbsp;&lt;/p&gt;
[quote user=""]In this case I can myself perform frequency hoping and power adjust - Isn&amp;#39;t it ???[/quote]
&lt;p&gt;&amp;nbsp;Also, yes.&lt;br /&gt;&amp;nbsp;&lt;/p&gt;
[quote user=""]In the NRF5 SDK I see in folder examples/peripheral/radio&amp;nbsp; 2 projects for transmitter and receiver - is it right scratchpad project for low level development ???[/quote]
&lt;p&gt;&amp;nbsp;Correct.&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;
[quote user=""]Meanwhile I searched setting TX power and mode and frequency, but don&amp;#39;t find any, except in start config. Where these 3 parameters are manipulating ???[/quote]
&lt;p&gt;&amp;nbsp;TX power&amp;nbsp;is the output power of the radio, in dBm. See&amp;nbsp;&lt;a title="TXPOWER" href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html?cp=4_0_0_5_19_13_45#register.TXPOWER"&gt;TXPOWER&lt;/a&gt;&amp;nbsp;for details.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;Mode is the modulation scheme, see&amp;nbsp;&lt;a title="MODE" href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html?cp=4_0_0_5_19_13_46#register.MODE"&gt;MODE&lt;/a&gt;&amp;nbsp;for details.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;Frequency is the frequency of the carrier, it controls what channel you use, depending on your protocol/modulation scheme. See&amp;nbsp;&lt;a title="FREQUENCY" href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/radio.html?cp=4_0_0_5_19_13_44#register.FREQUENCY"&gt;FREQUENCY&lt;/a&gt;&amp;nbsp;for details.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
[quote user=""]If we decide to make classic mesh - where are the most suitable example project ??? In Mesh SDK ??? Whitch one ???[/quote]
&lt;p&gt;&amp;nbsp;What is a classic mesh? You need to specify your needs or we can&amp;#39;t really help you. What is your end-goal?&lt;br /&gt;&lt;br /&gt;The Mesh SDK uses BLE Mesh, that in turn requires the SoftDevice to run.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
