RF4CE Network Processor Interface SubSystem

This page describes how to use the Network Processor Interface to interface with the RF4CE stack. RemoTI is the implementation of RF4CE for CC2xxx.

SubSystem IDs

There are two sub system IDs that can be used to interface with the RF4CE stack:

SubSystem ID SubSystem
0x0A RemoTI API
0x0B RemoTI Network Layer (RCN) API

Command ID to RemoTI API mapping

The APIs listed in the tables below are ordered by functionality, rather than ID.


  • Most APIs are asynchronous requests made by host that have an asynchronous confirmation.
  • They are typically called requests and confirmations.
  • Requests end with Req
  • Confirmations end with Cnf


  • Some APIs to host do not require a request. Some of those APIs require a response.
  • They are typically called indications and responses.
  • Indications end with Ind
  • Responses end with Rsp.
