Configure RPi 3 running HypriotOS v1 to run as a beacon

README.md

Setup RPi as iBeacon HypriotOS

On a fresh HpryotOS image, bluez is already installed and running. If you run the following command:

$ sudo hciconfig dev
hci0:	Type: BR/EDR  Bus: UART
	BD Address: B8:27:EB:B0:55:A9  ACL MTU: 1021:8  SCO MTU: 64:1
	UP RUNNING 
	RX bytes:724 acl:0 sco:0 events:43 errors:0
	TX bytes:1568 acl:0 sco:0 commands:43 errors:0

Open and initialize HCI device:

sudo hciconfig hci0 up

Enable LE advertising. The 3 means non connectable undirected advertising:

sudo hciconfig hci0 leadv 3

Prevent scanning:

sudo hciconfig hci0 noscan

Start advertising:

$ sudo hcitool -i hci0 cmd 0x08 0x0008 1E 02 01 1A 1A FF 4C 00 02 15 63 6F 3F 8F 64 91 4B EE 95 F7 D8 CC 64 A8 63 B5 00 00 00 00 C8 00
< HCI Command: ogf 0x08, ocf 0x0008, plen 32
  1E 02 01 1A 1A FF 4C 00 02 15 63 6F 3F 8F 64 91 4B EE 95 F7 
  D8 CC 64 A8 63 B5 00 00 00 00 C8 00 
> HCI Event: 0x0e plen 4
  01 08 20 00

Beacon UUID:

63 6F 3F 8F 64 91 4B EE 95 F7 D8 CC 64 A8 63 B5
