About BLE SMP
SMP message decoding identifies pairing phase and cryptographic control flow between peers, useful for security troubleshooting.
SMP handles BLE pairing, bonding, and key exchange for encrypted links and authenticated access.
BLE SMP Header Structure
- SMP Code (1 byte): pairing/key-distribution message type.
- SMP Parameters: method-specific fields and capability flags.
- Optional key material in later exchanges.
