Hi Luiz Augusto von Dentz,
Thank you very much for your reply. This should give me sufficient direction to go further.
The idea for our BLE central oriented platform (two boards solution) is to run on the BLE Host board Linux and thus depending on BlueZ. The BLE controller runs on a Nordic board Zephyr (HCI_UART).
Both boards will be bridged via a HCI uart(h4) transport layer.
Our BLE peripheral oriented platform might be a pure single board Nordic BLE Host Controller approach depending on Nordic's SoftDevice for the BLE stack.
