6. عملیاتي لارښوونې

The FSC-BT630 module operates primarily as a transparent UART bridge for Bluetooth Low Energy communication. Its functionality is typically controlled via AT commands or through a custom firmware application.

6.1. Initializing the Module

Upon power-up, the module will enter a default state, often discoverable or advertising. You can configure its behavior using AT commands sent over the UART interface. Common commands include setting the device name, baud rate, advertising parameters, and connection modes (e.g., peripheral, central).

6.2. د بلوتوث پیوستون

1. اعلانونه: The module can be configured to advertise its presence, allowing other Bluetooth devices (e.g., smartphones, other modules) to discover it.
2. سکینګ: If configured as a central device, the module can scan for other advertising Bluetooth devices.
3. د پیوستون تاسیس: Once discovered, a connection can be established. The module supports both BLE Client and Peripheral roles.
