My setup of consists of two identical NRF5340 based custom boards, running FW based on the nrf SDK v1.7.1. The devices are bonded, directed advertising one the 1Men-USTelligent Community 13Tue, 18 Oct 2022 15:26:51 GMThttps://devzone.nordicsemi.com/thread/391266?ContentTypeID=1Tue, 18 Oct 2022 15:26:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f14392a-728f-4b75-8ec0-5416b8150698Armin Schmidt<p>Thank you very much for your quick reply Simon!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/391228?ContentTypeID=1Tue, 18 Oct 2022 14:13:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7041ddb7-6081-4def-9dad-398cefae17b4Simonr<p>Hi</p> <p>This is a limitation of the Bluetooth spec. as directed advertising is designed to connect to a scanning device as quickly as possible, while the Coded PHY does all advertising and data transfers at ~1/8th the speed due to transmitting all advertisements multiple times on different secondary channels. Which is how Coded PHY increases the range of connections. See<a href="https://novelbits.io/bluetooth-long-range-how-to-achieve-results-over-1km/"> this blog post</a> on Coded PHY at NovelBits and the official &quot;<a href="https://www.bluetooth.com/blog/advertising-works-part-1/">how advertising works</a>&quot; blog on Bluetooth.com for info on directed advertising.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
