Apple

the iBeacon is sent through manufacturer option in Advertisement packet.

1A Message Length (26 bytes), including 0xFF and all following bytes
FF Manufacturer option

4C 00 Manufacturer ID (Apple's)

02 15 Apple specific, maybe defining the message type as "iBeacon" and it length (0x15 = 21 bytes = 16+4+4+1)

E2 C5 6D B5 DF FB 48 D2 B0 60 D0 F5 A7 10 96 E0 (16bytes for UUID)
00 42 (2bytes for major)
00 58 (2bytes for minor)

Subject: Decoding iBeacon BLE message
To: email@hidden

I try to understand the BLE message send by an iBeacon (from Apple sample app)

I have installed a BLE sniffer and I get the following message I have tried to decode

- Can someone help me to understand the remaining ?

- In addition I do not see any serviceID send in the message: Does it mean that the iBeacon can not be visible when the app is not in foreground ?

02 (length)
01 (GAP_ADTYPE_FLAGS)
1A ?
1A Longueur (message length)
FF 4C 00 02 15 ?

E2 C5 6D B5 DF FB 48 D2 B0 60 D0 F5 A7 10 96 E0 (16bytes for UUID)
00 42 (2bytes for major)
00 58 (2bytes for minor)
C5 (?)
