Data 180 (Scanned iBeacon Beacon Data)

The Beacons information collected by terminal. Each Beacon occupies 28 bytes, including Type, MAC, RSSI, etc.

The frame format of the Data 180 unit is as follows:

For example (Total 32 bytes):
80 B4 1D 01 0C 12 34 56 78 90 AB BB 11 22 33 44 AA BB 11 22 CC DD 00 11 22 33 44 55 00 01 00 01

Parts	Fields		Length (Byte)	Range/Format	Default

Length	Data Length		1 or 2	00H-7FH or 8080H-80FFH

	The first Beacon	Type	1

• Number

  Indicates how many Beacons the following data comes from.

  If the value of this field is 00H, no other fields are included.

• Type

  Indicates the type of the Beacon. It is refer to the parameter ‘Type’ in AT@BTBCN command.

  For example, 51H (i.e, 81) means the type is iBeacon.

• MAC

  The MAC address of a Beacon.

  For example, 1234567890ABH means the MAC address 12:34:56:78:90:AB.

• RSSI

  The received signal strength.

  Expressed as an 8-bit signed integer and the unit is dBm. When the RSSI value is less than -128 (80H), it is also filled in as 80H, and when the RSSI value is greater than -1 (FFH), it is also filled in as FFH. In particular, 63H means the signal strength is not known or not detectable.

  Typical values are as follows:

  Value	Signal Strength (dBm)	Level
  A7H to 80H	-89 or less	0
  A8H to ADH	-88 to -83	1
  AEH to B4H	-82 to -76	2
  B5H to BEH	-75 to -66	3
  BFH to FFH	-65 or greater	4
  63H	Not known or not detectable	/

• UUID

  Indicates the proximity UUID (Universally Unique Identifier) of the Beacon.

  For example, 11223344AABB1122CCDD001122334455H means the UUID “11223344-AABB-1122-CCDD-001122334455”.

• Major

  Indicates the Major value of the Beacon.

  For example, 0001H means the Major “0001”.

• Minor

  Indicates the Minor value of the Beacon.

  For example, 0001H means the Minor “0001”.
