Product review using several NRF52840 IC and USB Hub IC

[Danny.KIM]

Hello

I am considering a product that connects several NRF52840s to a USB 2.0 7-ch HUB and works with 30 BLE devices.
When reviewing a product like this, there are some questions

1. Was there a product made like this? I wish you could share some data for reference

2. And I plan to use multiple NRF52840s. How should I do image (FW) download?
I want you to tell me if you need to download images by connecting each one or if there is a way to download multiple images at once.

Please confirm

Thank you

I am a bit confused by your question: "Product review" suggests that you have a product, and you are going to review it. But then you ask if the product exists.

So are you reviewing existing product(s), or just searching to see if such a thing exists?

Drawing a diagram of your requirement would help.

Note that a single nRF52840 can support up to 20 simultaneous BLE connections.

Sure, you could run multiple instances of the programmer.

Or google "production programmer" ...
