Hey Simon 👋🏻

Thank you so much for your guidance and examples!

To answer your question, the number of remote devices will be limited, typical 1-3, updated 30-60min, so there won't be too much frequent communication happening.

I like example 2 as well, as it will be more flexible for configuration and future updates — no need to update HW, just the app on Mac or Win. Btw. good point on the HID overload, I did not think about it that way, that it could be a bottleneck.

Have a great day,

Cheers,
Tom

Do you have any idea how many remote devices you would be looking to have in this network? You might not need a mesh network if the amount of remote devices is limited.

For convenience sake I personally would go for example 2 here I think. As example 1 would need the HID device to take care of all communication from the remote devices, which might make the HID experience falter if it's a lot of data to process simultaneously as acting as a HID device, while the computer should be able to handle multiple peripherals. This would have the computer be the client and the HID device and all remote devices be servers.

Please check out the HID examples in our SDK, and something like the BLE Blinky or heart rate application for an example of how the remote devices could be used.

Best regards,

Simon
