BLE Advertising Packet Builder using BleuIO

What is a BLE Advertising Packet?

BLE advertising packets are small data broadcasts used by Bluetooth devices to announce their presence. A basic packet includes:

• Preamble (1 byte) - Usually handled by hardware
• Access Address (4 bytes) – Always 0x8E89BED6 for advertising packets
• Header (2 bytes) – Indicates packet type and length
• Payload (up to 31 bytes) – Includes device name, manufacturer data, etc.
• CRC (3 bytes) – Calculated by hardware

With BleuIO, we mostly control the payload and advertising parameters.

Note that certain Types have certain rules and conventions that should be followed, for example Complete Local Name should only be added once, in either the Advertising Data or the Scan Response Data.
By default the BleuIO Dongle already has a Complete Local name 'BleuIO' or 'BleuIO Pro' set in the Scan Response Data.
