https://devzone.nordicsemi.com/f/nordic-q-a/100682/problems-with-homekitDear Support Team, Please help confirm the following three points: 1. The nRF5 SDK only supports HomeKit ADK V4. Will there be any technical risks when porting the latest ADK to the nRF5 SDK? What is the approximate workload? 2.Thread homekit needs toen-USTelligent Community 13Mon, 12 Jun 2023 10:23:57 GMThttps://devzone.nordicsemi.com/thread/430429?ContentTypeID=1Mon, 12 Jun 2023 10:23:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:34cdf294-ef87-4e41-bd26-1e4e2ea34a84Susheel Nuguru[quote user=""]1.

We do not know the efforts and risks that is involved in porting nRF5SDK for Homekit to use ADKv5 since we have not done those efforts inhouse.</p> [quote user=""]2.Thread homekit needs to use BLE to configure the network, does it also support BLE homekit?[/quote] <p></p> <p>Can you be more specific in what you mean here? Thread can use BLE for configuring and provisioning the device into the network. But the device being a thread homekit device can also be a BLE homekit device. I am not sure if we support that on all devices due to memory constraints.</p> [quote user=""]3. NCS adopts A/B partitions. For the space that does not need to be upgraded, such as the protocol stack or user data, it should not occupy the backup space, right?[/quote] <p>Yes, that is my understanding aswell.</p><div style="clear:both;"></div>
