HCI controlling interface nRF52

[Oleg]

Hi dear Nordic Engineers.

We going to move from FN-LINK (Realtek) I.C. BLE to nRF52. FN-LINK uses HCI (UART) BLE the Interface to communicate with our embd. LINUX. How to up HCI interface with nRF52 to move in the easiest way ? Maybe some existing source codes / examples / libraries ? (we assume to use S132 because Peripheral & Central roles work concurrently)

Thanks you!

sorry I'm a little confused... , Nordic does not prov. example, but DOES fully provide HCI ? I found (in SDK 12.1.0) the HCI Transport module:

QUOTE: "... HCI transport module implementation. This module implements certain specific features from the three-wire UART transport layer, defined by the Bluetooth specification version 4.0 [Vol 4] part D. ... "

and from BT official spec.:

is SDK 12xx HCI compatible with BT official UART HCI ? does SDK12 supports HCI fully ?

The transport layer, meaning the physical layer, is supported, but the actual commands that goes over is not compatible with linux. There is a serialization protocol available from Nordic, but it is not pluggable into linux. Zephyr and NimBLE is compatible with the linux bluetooth stack bluez.
