Hi,

We want to port our custom Bluetooth controller to run on Zephyr RTOS (not using the default zephyr ble controller support). I went through the Bluetooth documentation https://docs.zephyrproject.org/latest/guides/bluetooth/index.html ,https://docs.zephyrproject.org/latest/guides/bluetooth/bluetooth-arch.html. The link’s talks about Bluetooth host in detail and it was helpful. We want to use Dual Chip configuration mode (use Zephyr Bluetooth host + custom Bluetooth controller support) .

From link it talks about various host only build configuration
o CONFIG_BT =y
o CONFIG_BT_HCI =y
o CONFIG_BT_CTLR =n


My query is in order to port custom controller what steps, build configuration we need to take care of. If there is a link/document that helps to describe porting of custom Bluetooth controller to Zephyr it will be helpful.

-thanks
