 We are using the NUS service to transmit some data. To comply with certain CEM tests and regulations, we need the ability to configure BLE to publish on specific frequencies for some test purposes. 
 Since BLE has 40 channels—3 for advertising</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Sat, 15 Feb 2025 11:44:08 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/118991/change-select-ble-channels" /><item><title>RE: Change/Select BLE channels</title><link>https://devzone.nordicsemi.com/thread/523123?ContentTypeID=1</link><pubDate>Sat, 15 Feb 2025 11:44:08 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f3f172ed-9dfa-4d66-ad4c-e60bdea4359e</guid><dc:creator>Ih3b</dc:creator><description>&lt;p&gt;Thanks for these examples that I will definitely look into in details.

Then you can test to send various patterns on various channels. When you are done with testing, reflash your device with your normal firmware.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
