1# BTstack Port for POSIX Systems with Intel Wireless 8260/8265 Controllers
2
3Same as port/libusb, but customized for Intel Wireless 8260 and 8265 Controllers.
4These controller require firmware upload and configuration to work. Firmware and config is downloaded from the Linux firmware repository.
5
6## Compilation
7
8Requirements:
9- [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/)
10- [libusb-1.0](http://libusb.info)
11
12On a recent Debian-based system, all you need is:
13
14 apt-get install gcc git libusb-1.0 pkg-config
15
16
17When everything is ready, you compile all examples with:
18
19 make
20
21## Environment
22
23On Linux, the USB Bluetooth dongle is usually not accessible to a regular user. You can either:
24- run the examples as root
25- add a udev rule for your dongle to extend access rights to user processes
26
27To add an udev rule, please create `/etc/udev/rules.d/btstack.rules` and add this
28
29 # Match all devices from CSR
30 SUBSYSTEM=="usb", ATTRS{idVendor}=="0a12", MODE="0666"
31
32 # Match DeLOCK Bluetooth 4.0 dongle
33 SUBSYSTEM=="usb", ATTRS{idVendor}=="0a5c", ATTRS{device}=="21e8", MODE="0666"
34
35 # Match Asus BT400
36 SUBSYSTEM=="usb", ATTRS{idVendor}=="0b05", ATTRS{device}=="17cb", MODE="0666"
37
38 # Match Laird BT860 / Cypress Semiconductor CYW20704A2
39 SUBSYSTEM=="usb", ATTRS{idVendor}=="04b4", ATTRS{device}=="f901", MODE="0666"
40
41 # Match Intel Wireless 8260 8265
42 SUBSYSTEM=="usb", ATTRS{idVendor}=="8027", ATTRS{device}=="0a2b, MODE="0666"
43
44On macOS, the OS will try to use a plugged-in Bluetooth Controller if one is available.
45It's best to to tell the OS to always use the internal Bluetooth Contoller.
46
47For this, execute:
48
49 sudo nvram bluetoothHostControllerSwitchBehavior=never
50
51and then reboot to activate the change.
52
53## Running the examples
54
55BTstack's HCI USB transport will try to find a suitable Bluetooth module and use it.
56
57On start, BTstack will try to find a suitable Bluetooth module. It will also print the path to the packet log as well as the USB path.
58
59 $ ./le_counter
60 Packet Log: /tmp/hci_dump.pklg
61 USB Path: 03-01-04-03
62 Firwmare ./ibt-12-16.sfi
63 Firmware upload complete
64 Firmware operational
65 Done 1
66 BTstack counter 0001
67 USB Path: 03-01-04-03
68BTstack up and running on F8:34:41:D5:BE:6F.
69
70If you want to run multiple examples at the same time, it helps to fix the path to the used Bluetooth module by passing -u usb-path to the executable.
71
72Example running le_streamer and le_streamer_client in two processes, using Bluetooth dongles at USB path 6 and 4:
73
74 ./le_streamer -u 6
75 Specified USB Path: 06
76 Packet Log: /tmp/hci_dump_6.pklg
77 USB Path: 06
78 BTstack up and running on 00:1A:7D:DA:71:13.
79 To start the streaming, please run the le_streamer_client example on other device, or use some GATT Explorer, e.g. LightBlue, BLExplr.
80
81 $ ./le_streamer_client -u 4
82 Specified USB Path: 04
83 Packet Log: /tmp/hci_dump_4.pklg
84 USB Path: 04
85 BTstack up and running on 00:1A:7D:DA:71:13.
86 Start scanning!
