Data basics

Data between Unio and the client is represented in JSON format like the following.

{"serial":NUMBER, "uuid":"UUID", "data":ByteArray}

Here,

• Number: Integer value. NUMBER >= 1. Unio will generate a corresponding serial number for each toio.
• UUID: UUID corresponding to the toio characteristic.
• BYTE_ARRAY: Array of byte values.

The following data sent from the client to Unio represents a request to start a connection toio.

{"serial":0, "uuid":"", "data":[]}
