8.2 G​ATT Specifications

In BLE, an attributes is the smallest data entity defined by GATT. Attributes are used to describe the hierarchical data organization, such as Services and Characteristics, and pieces of the user data. A Service conceptually groups all the related Characteristics together, and each Characteristic always contain at least two attributes: Characteristic Declaration and Characteristic Value.

cc-bnp will automatically parse the attributes if they are publicly SIG-defined ones or BIPSO-defined ones by using ble-packet module.
