Re: Query regarding Bluetooth Controller Porting

Pankaj,

If you are using a dual-chip solution, then as long as you controller complies with standard HCI there is no "porting" to do whatsoever.
In order to better understand what you need, can you let us know which transport do you plan on using (UART/H4, 3-wire/H3 or SPI) and whether it is a single-mode or dual-mode controller?

Unless your controllers has special requirements it should all be a matter of configuring the right Kconfig options and Devicetree nodes.

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

ku7XtLCnOWo%3D&amp;reserved=0. 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
