I am using this code to work with the Bluetooth gatt services on raspberry pi. I would like to know how do I set multiple characteristics (like read, write, notify) to one service using the following function. Characteristic.__init__(self, bus, index, UART_TX_CHARACTERISTIC_UUID, [‘notify’], service)
Look at the code and table in the previous section before answering. A reserved range of 2^32 values can be represented using 32 bits (denoted uuid32). This is how you know what the value means.

A 16-bit Universally Unique Identifier (UUID) may be allocated by the SIG for use with a custom GATT-based service defined by the member. UUIDs are used in Bluetooth® protocols and applications. The SIG provides UUIDs for all the types, services, and profiles it defines. A fee of 2500 USD will be charged for each UUID.

In Bluetooth, attributes types, GATT service types, characteristic types and descriptor types, and other constants are identified through UUIDs. UUIDs are no more than identifiers, 128-bit identifiers. One given 128-bit value designates one given thing.
