Running on Arduino, this program can send sensor data to Raspberry Pi.

Built for BlueSense-NG. For previous versions, refer to legacy branch.

These libraries are embedded in this project.

• serialpb (BufferProtocol.[h|cpp])
• protobuf generated files (sense.pb.[c|h])

You'll need to install the following dependencies yourself.

• nanopb (use vcpkg or other tools to install protoc plugin, and also install it in Arduino libraries folder)
• BME280 https://github.com/finitespace/BME280
• Python 2.7 and protobuf (required by nanopb generator plugin)

All packets are encapsuled in serialpb buffer protocol. For each packet,

The first byte indicates channel.

• nanopb packet begins with 0x00, then follows raw nanopb (protobuf) data.
• PM2.5 sensor data begins with 0x01, then follows raw serial data.
• log message begins with 0x02, then follows the byte string.
