The packet is in customize format and it describe the device information. It also advertises iBeacon protocol data. Which information do you need about the beacon? ---

Hi, Is my device April Bacon N02? Or what device is it? I am trying to decode this advertising message following the iBeacon format (described in [https://en.wikipedia.org/wiki/IBeacon#Packet\_Structure\_Byte\_Map](https://en.wikipedia.org/wiki/IBeacon#Packet_Structure_Byte_Map)): Data: 00 12 3B 6A 1B 5A A3 C4 02 01 06 03 03 F5 FE 14 FF D2 00 01 E5 73 38 E6 D8 54 58 10 75 82 83 BF 31 54 02 40 As per shown here [https://wiki.aprbrother.com/en/User\_Guide\_For\_AB\_BLE\_Gateway\_V4.html](https://wiki.aprbrother.com/en/User_Guide_For_AB_BLE_Gateway_V4.html) Advertising type: 00 Mac addr: 12 3B 6A 1B 5A A3 Rssi: C4 iBeacon raw advertising data Standard ble flags: 02 01 06 The following bytes are the iBeacon data, but II don’t know in which way the are formatted,a nd you don’s specify it anywhere on your site. 03 03 F5 FE 14 FF D2 00 01 E5 73 38 E6 D8 54 58 10 75 82 83 BF 31 54 02 40 Your Android app decodes it into UUID, major, minor, and distance. But I want to build my own app. How is this done? Thanks ---

hi, It advertises 3 iBeacon protocol data and 1 customized device data. You should filter out the customized device data first. Please also check the link about [iBeacon profile](https://stackoverflow.com/questions/18906988/what-is-the-ibeacon-bluetooth-profile)
