5.3 Bluetooth Client App Workflow
The following sections describe a suggested workflow for the Bluetooth Client to connect and transfer
data.

5.3.1 Bluetooth Client Establishing a Connection

The Bluetooth Client searches for the DLP NIRscan Nano using the GAP for discovery. Once the
Bluetooth Client detects a DLP NIRscan Nano, the Bluetooth Client reads the DLP NIRscan Nano
advertized packets, establishing a connection.
