Key Considerations When Choosing Bluetooth Solutions

  1. Range: Use Bluetooth 5.0+ for up to 100m line-of-sight. Add repeaters or mesh for larger areas.
  2. Power: Opt for BLE devices with long battery life (e.g., 2–5 years).
  3. Integration: Ensure compatibility with existing gateways (e.g., LoRa, Wi-Fi) or cloud platforms (AWS, Azure).
  4. Cost: BLE sensors are affordable (10–10–50 per node) compared to cellular IoT.

Complementary Hybrid Solutions

Pair Bluetooth with long-range tech for full coverage:

  • Bluetooth + LoRa: Sensors send data via BLE to a LoRa gateway for long-distance transmission.
  • Bluetooth + Satellite IoT: Remote farms use Bluetooth for local data collection and satellite for global connectivity.

Future-Ready Bluetooth Innovations

  • AI-Enabled Edge Devices: Bluetooth sensors with onboard AI (e.g., disease detection in crops).
  • 5G-Bluetooth Convergence: Ultra-reliable connectivity for autonomous farm machinery.
