Remote procedure call library (nRF RPC)
nRF RPC is a remote procedure call library for nRF Connect SDK enabling inter-processor communication on Nordic Semiconductor SoCs. The library is RTOS-agnostic and implements serialization of function calls. It is designed to be used with an underlying transport layer, for example OpenAMP.
The nRF RPC library allows for calling a function on remote processors from a local processor, in both synchronous and asynchronous way.
Depending on the transport layer, the remote processor is not limited to a single device. It can also be a separate device of any type (for example, a PC), or another core on the same system.
The nRF RPC library simplifies the serialization of user APIs, such as a Bluetooth stack, and executing of functions implementing those APIs on a remote CPU. The library is operating system independent so it can be used with any operating system after porting the OS-dependent layers of the library.
The API layer on top of the core nRF RPC API uses the TinyCBOR library for serialization. nRF RPC requires the Zephyr Project fork of TinyCBOR, because of API differences.
