This has been so helpful , thankyou so much for this 5 min video!

[@steve_____K307]

Interesting. Thank you. Do those TI devices require any special library be built in such that HomeKit can add the accessory to the user's HomeKit accessory database? I know that in the [recent] past TI offered the HomeKit Plug-in library (to be used with the TI SDK) that implements the Apple HomeKit Accessory Protocol (HAP) for normal 2.4GHz wifi networks. Is there another sort of library that TI offers that supports HomeKit for Thread devices implemented with the TI chips and SDKs?

How many devices can be supported in a border router? Since IEEE802.15.4 has only 250kbps bandwidth, and 6LowPAN stills has a much bigger overhead than other proprietary RF packets? Is there any method to get the topology of current mesh network?

[@matthewforan6397]

According to Nordic Semiconductor's video on the topic, you can have "up to 32 routers per network and up to 511 end devices per router". Since Thread is targeting low-power IoT devices, bandwidth is typically not an issue. If you do run into problems you could use additional border routers. On large networks that would be advisable anyways to minimize the number of hops needed to reach the border. To answer your second question, Nordic created a tool called the nRF Thread Topology Monitor.

IEEE 802.15.4 conforming bands are 868/915/2.4g which frequency band is this demo in? If 2.4g aren't the battery demands a bit steep? oh ugh!!! the device link says Bluetooth was used. Is that correct?.

[@matthewforan6397]

Yes, that device uses 2.4GHz since the band is available worldwide. A home mesh network allows you to use low power radios because the devices are typically close together. In Thread you can also use a "Sleepy End Device" which only wakes up occasionally to check for messages. The TI device supports Bluetooth but this video is about Thread, which is a different network protocol.

I just bought Amazon Eero which Support the thread protocol - but I can't find any devices to buy on Amazon.. Does anybody may have a hint for me where to buy compatible (light bulbs)?

[@crwblyth]

Nanoleaf just announced their Essentials range that are Bluetooth or Thread compatible. Whether they work with the Amazon Eero, I have no idea.

[@craftrobot]

@@crwblyth Soon. Call Nanoleaf. They have a beta program. Same for Eero. Good future roof decision to rush case that router. The thread chip is in there. BTW these already work with the HomePod mini. :)

Can I use thread and rtls code in same code ? If yes what I need to do?
