Bluetooth
The Bluetooth feature enables wireless short-range communication using Bluetooth Low Energy (BLE) technology. This allows mobile device connectivity, sensor integration, and local device configuration.
Overview
Bluetooth connectivity enables:
- Mobile app control via LUIS
- Device configuration and provisioning
- Local data exchange
Bluetooth Low Energy (BLE)
AppBlocks uses Bluetooth Low Energy for:
- Low power consumption
- Modern smartphone compatibility
Configuration
Configure Bluetooth with these properties:
- Device Name: Visible name in Bluetooth scans
LUIS Mobile App Integration
The primary use of Bluetooth is connecting with the LUIS Mobile App:
- Monitor device variables and status
- Update settings and configuration
- Provision WiFi credentials
Range and Power
Typical Bluetooth LE range:
- Indoor: 10-30 meters
- Outdoor: up to 100 meters (with clear line of sight)
- Factors: Obstacles, interference, antenna design
Power consumption considerations:
- BLE uses minimal power when idle
- Advertising mode consumes more power
Linking to Settings
Bluetooth properties can be linked to settings for:
- Custom device naming
Related Features
- LUIS Mobile App: Mobile device management
- WiFi: WiFi provisioning via Bluetooth
- Settings: Configuration management
Use Cases
Common Bluetooth applications:
- Initial device setup and WiFi provisioning
- Mobile operator control panels
- Local diagnostics and troubleshooting
Bluetooth and WiFi Coexistence
When using both Bluetooth and WiFi:
- Both operate on 2.4 GHz band
- Modern chipsets manage coexistence automatically
- Minimal interference with proper firmware
Troubleshooting
Common Bluetooth issues:
- Cannot discover device: Check visibility settings and power
- Connection drops: Reduce distance or remove obstacles
- Interference: Move away from other 2.4 GHz devices
