This is news to me and, although it might be expected, I would like to check with a couple of people. So I think this deserves being tracked. Would you mind opening a “Question” issue on GitHub so I can copy the relevant people and we can investigate a bit further? If you have any code snippets that you can attach to the issue that would be most helpful as well.

After implementing a throughput test for BLE using #nrf52840 hardware and Zephyr 1.14-rc1, notice some curious behavior in data we are collecting. The test seems to show that sending data from the central (client) to peripheral (server)
throughput performance is relatively balanced per connection but one peripheral seems to get little data and one peripheral get more. In data flow from the peripherals to the central, it is much more unbalanced with one or two peripherals having all the throughput
and the others having none.
