Can I use a smaller connection interval value than 7.5ms?https://devzone.nordicsemi.com/f/nordic-q-a/85879/can-i-use-a-smaller-connection-interval-value-than-7-5msHi Nordic, I have 2 devices - nrf52840. One is Central and another is peripheral. I want to set a quicker data response time - shortest connection interval. As far as I know, the BLE standard min CI is 7.5ms. However, since I am using my own customizeden-USTelligent Community 13Wed, 16 Mar 2022 10:35:23 GMTRE: Can I use a smaller connection interval value than 7.5ms?https://devzone.nordicsemi.com/thread/358371?ContentTypeID=1Wed, 16 Mar 2022 10:35:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4994cd56-bb1b-4397-a9be-7371c527cf18LeonWu<p>Hi Vincent,</p> <p>For standard BLE, that will be challenging, but you can refer our latest LLPM to achieve the target:</p> <p><a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/nrf/samples/bluetooth/llpm/README.html?highlight=llpm">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/nrf/samples/bluetooth/llpm/README.html?highlight=llpm</a></p> <p>The LLPM needs to be with NCS, and you can check the development guideline here, it is written by Nordic FAE manager in China:</p> <p><a href="https://www.cnblogs.com/iini/p/14174427.html">https://www.cnblogs.com/iini/p/14174427.html</a>&nbsp;</p> <p>My understanding that you are using a nRF52840 based module, right? So you should be able to adopt it, we also have some successful story on mice:&nbsp;<a href="https://www.nordicsemi.com/News/2022/02/G-Wolves-uses-nRF52840-in-The-Hati-ACE-computer-peripherals">https://www.nordicsemi.com/News/2022/02/G-Wolves-uses-nRF52840-in-The-Hati-ACE-computer-peripherals</a></p> <p>Thanks!</p> <p>Leon</p><div style="clear:both;"></div>
