This documents the binding structure and common properties for serial
|
|
attached TI Bluetooth devices. The following chips are included in this
|
|
binding:
|
|
|
|
* TI CC256x Bluetooth devices
|
|
* TI WiLink 7/8 (wl12xx/wl18xx) Shared Transport BT/FM/GPS devices
|
|
|
|
TI WiLink devices have a UART interface for providing Bluetooth, FM radio,
|
|
and GPS over what's called "shared transport". The shared transport is
|
|
standard BT HCI protocol with additional channels for the other functions.
|
|
|
|
TI WiLink devices also have a separate WiFi interface as described in
|
|
wireless/ti,wlcore.yaml.
|
|
|
|
This bindings follows the UART slave device binding in ../serial/serial.yaml.
