Texas Instruments RF4CE application for a Linux host using a CC253x RNP
This repository contains the UART, SPI and I2C drivers, and associated make files and header files for interfacing with a Texas Instruments CC253x RF4CE device configured in RemoTI Network Processor (RNP) mode. It also contains the RemoTI (RTI) API to be used by the application developer when communicating with the CC253x, and a sample application to illustrate the use of the RTI API. All these files are delivered under the TI BSD license with the license terms included at the top of each file.
RemoTI is the implementation of the RF4CE specification by Texas Instruments. The RemoTI software installer can be downloaded at http://www.ti.com/remoti. Note that this installer is delivered under different terms than the TI BSD license. You must accept the RemoTI terms and conditions separately during the installation process.

RemoTI-Linux is a multiprotocol driver. It supports all physical serial protocols supported by CC253x devices, s.a. UART, I2C, SPI and USB. The driver is divided in two parts. The first part, the NPI Server, converts the physical serial protocol to a socket. The second part, generally called NPI Client, constitutes converting the serial commands to C API. These C APIs can be added to your own application. Multiple NPI Clients can connect to a single NPI Server. This allows multiple applications to use RF4CE data, s.a. Consumer Control, Keyboard and Mouse.
Please see http://processors.wiki.ti.com/index.php/RF4CE,_simple_linux_target_application for more details.
The makefile in /Projects/tools/LinuxHost/ will build the NPI_Server for the following
platforms:
- Current host platform using default gcc
- BeagleBoard xM using arm-none-linux-gnueabi-gcc
- BeagleBone using arm-arago-linux-gnueabi-gcc
If you are missing any of the arm compilers the compilation will exit with error. However, the current platform is still built.
$ cd Projects/tools/LinuxHost
$ make
The makefile in /Projects/tools/LinuxHost/application/Simple will build a simple console
application to configure and control a RemoTI Network Processor (RNP).
$ cd Projects/tools/LinuxHost/application/simple
$ make
If you are testing the driver for an RNP built on CC2531 then first lookup what device it has
enumerated as. Typically this will be ttyACM0. You can have RNP on CC2531 by flashing the image
C:\Texas Instruments\RemoTI-CC253xDK-1.3.1\bin\RNP-CC2531F256.hex. See http://www.ti.com/remoti
and http://www.ti.com/tool/packet-sniffer. To modify the device change the path inside the .cfg file.
Then to execute the driver;
$ sudo ./out/NPI_lnx_x86_server configuration/x86/RemoTI_RNP_ACM0.cfg
If you have an NPI_Server running locally you can run the simple application like this;
$ ./out/SIMPLE_lnx_x86_client -D 127.0.0.1:2530
If you want to connect and control an NPI_Server running on another platform you need to its IP address
and port. This address and port is found in the output from the NPI_Server at startup. Alternatively
you can find the port by reading the configuration file used by the NPI_Server, and find the IP address
by typing $ ifconfig on the platform running the NPI_Server.
