Establishing a BLE 2M PHY connection between the nRF8240 and a MacBook Pro M1 running Mac OS Montereyhttps://devzone.nordicsemi.com/f/nordic-q-a/90976/establishing-a-ble-2m-phy-connection-between-the-nrf8240-and-a-macbook-pro-m1-running-mac-os-montereyDear Nordic, We&#39;re developing an application using the nRF52840 as a peripheral. In the role of central we have three different devices we&#39;re using:.

However, the peripheral can request a PHY update by doing a PHY update procedure. Have you tried that? If using the nRF5 SDK and SoftDevice, you can use&nbsp;sd_ble_gap_phy_update(), and if using nRF Connect SDK, use&nbsp;bt_conn_le_phy_update().</p> <p>Einar</p><div style="clear:both;"></div>
