Zephyr HCI amount of concurrent central connections

Hello @josef. Have you found an answer to this very good question? I'm currently struggling with HCI_USB being able to only handle one connection and throwing "Memory capacity exceeded" in btmon... While some cheap generic BLE dongles with fraction of memory from nRF52840 don't complain up to 5 connections so I'm quite puzzled by that.

-- Update

Just after writing this message I've found this https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_BT_MAX_CONN.html So for anyone else burning the midnight oil in search for the answer, hope that helps.

Hi Kenneth,
Understood. Since Nordic did the Qualification of the Zephyr BLE controller for nRF52, I thought someone here might know an answer...

Zephyr project is maintained by the zephyr community. I'd recommend asking them directly about this:
