@helium/proto v2.2.0

Using this repository requires protobuf's protoc to be installed. The package to be installed differs per host platform.

Contributing

• Protobuf message definitions live in either:
  • src/service/*.proto if only used in gRPC service definitions, or
  • src/*.proto if used by service-free code or shared across gRPC services
• Avoid float in Protobufs because representations differ across hardware architectures
  • There are many floating point representations from IEEE, plus others
  • i.e., some range of interior digits are random per float spec
• Frequency should use uint32 and should be in Hz
• rssi or signal is always negative, thus use sint32 and is in deci-dbm (aka ddbm) which is dbm * 10
• snr is signal-to-noise ratio and should be uint32
• Fetch and share time in nanos, then truncate to appropriate granularity as needed
  • e.g., get from OS in nanos
• Reject any PR unless units are documented inline within Protobuf definition
• Document units of fields
• When exceptions to the above occur, please explain why within comments
