https://devzone.nordicsemi.com/f/nordic-q-a/97231/about-llpm-s-protocolHi： May I ask 2 questions about LLPM&#39;s protocol. 1. BLE have 3types : 1M 、2M and BLE coded 。 During the application of LLPM in nRF52xxx chip, which type do you use, and why ? 2. Does LLPM support power control which been added in BT 5.2 ?

So using the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/bluetooth/hci_pwr_ctrl/README.html">HCI power control </a>you should be able to mix these two. I haven&#39;t verified this myself though.</p><div style="clear:both;"></div>
