Logging Remote Procedure Call

The Logging Remote Procedure Call (RPC) library enables receiving and managing log messages from a remote device or processor.

Overview 

The library supports the following main features:

Log streaming, which allows for receiving log messages over RPC in real-time as they are generated by the remote device.

Log history, which allows for saving log messages in a ring buffer in RAM or persistent memory, and retrieving them over RPC when needed.

The library also supports retrieving a core dump stored in the remote device’s memory, and setting the current time used for log timestamping.

Implementation 

The logging RPC consists of the following components:

Zephyr’s Logging backend that implements sending log messages using Remote procedure call library (nRF RPC). It also accepts RPC commands for managing the logging backend.
A log forwarder, which implements receiving log messages from a remote device and passing them to the local logging subsystem. It also implements RPC commands for managing the logging backend on the remote device.
