Nordic nRF52832 for Bluetooth Mesh Network

• To use system both indoors and outdoors, LoRa "Long Range" is the best option. Bluetooth can be used for network
  • Need to find microcontroller to be slave controller.
• Chips that GenOptic said they're using:
  • Nordic Semiconductors Bluetooth Low-Power Modules
  • Nordic Semiconductors Github
• Nordic nRF52832 should be capable enough for the local modules.
  • Nordic nRF52832
  • This chip has a development board that is currently available on Digikey. There is a lot of documentation for getting started in the link above.

Bluetooth Mesh Network Configuration

Bluetooth Mesh Overview

• sensor_client: collecting all the sensor data from nodes
• sensor_server: collecting data from sensors and sending it to mesh (server_client)
• Raspberryi Pi 5 does not possess a Bluetooth mesh stack so a proxy node is needed
• Proxy node: allows legacy Bluetooth LE devices to participate in the mesh network by establishing a GATT connection to a mesh device that has the proxy feature enabled (Proxy node)
