Unique ID (UID)
Functions§
- uid
- Get this device’s unique 128-bit ID. The datasheet (seems to) specify a 128-bit UID, while the SDK uses 96-bit. We read the full 128 bits to ensure uniqueness. Note that the last 4 bytes of the ID consist of unknown “internal coding” and fixed values.
- uid_hex
- Get this device’s unique 128-bit ID, encoded into a string of 32 hexadecimal ASCII digits. See documentation for
uidfor caveats. - uid_
hex_ bytes - Get this device’s unique 128-bit ID, encoded into 32 hexadecimal ASCII bytes. See documentation about
uidfor caveats.
