The main usage of the Radio Tool is to serve as a control panel for direct access to the Radio. It can be used for the RF evaluation and for certification purposes (Like FCC, ETSI, Telec etc.). The tool is expected to work seamlessly on TI evaluation platforms: Boosterpack+ FTDI emulation board for 3100 and Launchpad for 3200. If customers want to use the tool on their final platform please refer to the section 10 "Hardware connections on Non TI EVMs". The IO levels of these lines should be kept at VBAT level (same voltage that powers the 3100/3200 device).

Please refer to CC31xx Datasheet and CC32xx Datasheet for reference RF numbers.

NoteNote: The Radio Tool version matches SDK verion. For example, if the Radio Tool has a version as 0.5.x.x, you'll need to flash the devices with Service Pack 0.5.x.

Exclamation-icon.jpg Warning: We found a flaw in SDK 1.1.0 causing the Carrier Wave(CW) to malfunction. In general, you'll experience the following problem when using RadioTool 1.1:
  • Cannot stop CW after starting CW TX
  • Cannot change CW tone

This is partially fixed in the version 1.1_fix. For CC3100, the fix is already incorporated in the source code and binary. For CC3200, only the provided binary file has this fix applied because this requires the user to modify the simplelink\source\driver.c source file as provided in the SDK. If you are using the provided cc3200 binary, no action is required from your end.

If you need to compile your own radio tool binary file with the corrected CW mode functionality, please incorporate the following change: In line 805 of simplelink\source\driver.c, please change from:

if (pCmdExt && pCmdExt->RxPayloadLen < 0 && pCmdExt->TxPayloadLen)


if (pCmdExt && pCmdExt->RxPayloadLen < 0)

Please note that this change is only for fixing the CW issue for radio tool (or transceiver mode). If your application does not utilize this functionality, please change it back to default as we do not know the side effect of this change outside of radio tool context.


Software downloads

NoteNote: These are required in order to run the Radio Tool application. A DLL error during running with regards to MSVCR100.dll will occur if any of these are missing.


See the latest complete list of supported hardware at CC31xx Release Notes and CC32xx Release Notes.

Radio Tool Installation Directory

The installation process is pretty straight by following the steps. The default installation location is C:\TI, but you are able to change it to anywhere you want.

Here's the file directory structure after installation:

  • Installation directory
  • RadioToolApplication
- The Radio Tool GUI application (RadioToolGUI.exe), Radio Tool CLI application (RadioToolCLI.exe), and 3 pre-compiled DLL files (CC3100Lib.dll, CC3100LibUART.dll, CC3200Lib.dll).
  • RadioToolApplication_Source
- The Radio Tool application source for development. Use Visual Studio to open the file RadioToolApp.sln.
  • CC32xxBoardApplication_Binary
- CC32xx MCU images. Use these with Uniflash in order to flash a MCU image onto the device. See Flashing the board section.
  • CC32xxBoardApplication_Source
- CC32xx MCU image source for development. Place the radiotool folder under your CC3200 SDK example directory, and use CCS to open the project in the ccs folder inside.

Hardware connections

3100 Booster pack + Emulation board

Connect the RF connector (J2 or J3) to a WLAN tester/RF equipment for measurements and the J1 USB connector on the emulation board to the PC. Make sure the RF connection to the instrument in made BEFORE powering ON the board so that the right load impedance is provided during power ON.

The RF path to J3 (murata RF switch) is always present. In case you want to use J2 (uFL)for RF measurements the path to the antenna needs to be disconnected (depopulate R6) and path to J2 connector is enabled by populating R7.

  • Using UART interface

The emulation board would enumerate the following UART ports on the PC , select the 3rd COM port in the tool.

Emulationboard COMports.png

  • Using SPI interface

SPI interface doesn't require users to choose a specific COM port. Simply select the "CC3100 SPI" option in the tool to start connection. Warning Warning: With SPI connection, only one CC3100 can be connected to a PC at the same time because the Radio Tool doesn't know which CC3100 device to connect to if multiple CC3100 devices are present.

For large number testings, we recommend using the "CC3100 UART".

3200 LaunchPad

Connect the RF connector (J18 or J24) to a WLAN tester/RF equipment for measurements and the USB connector on the LaunchPad to the PC.Make sure the RF connection to the instrument in made BEFORE powering ON the board so that the right load impedance is provided during power ON.

The RF path to J24 (murata RF switch) is the default. Incase you want to use J18 (uFL) for RF measurements you need to disconnect the J24 path (depopulate R111) and enable the J18 path by populating R110.

The LaunchPad would enumerate the following COM port on the PC. Select that COM port in the GUI.

Flashing the board

The devices need to be flashed with the correct firmware in order to operate this tool correctly. Please refer to the #Releases section for the correct servicepack and/or application binary to be flashed.


Please refer to the CC31xx & CC32xx UniFlash for instruction on how to flash firmware onto the CC3100 board.


Put on the SOP2 jumper.

Please refer to the CC31xx & CC32xx UniFlash for instruction on how to flash the board with firmware and application binary. The binary files can be found in the CC32xxBoardApplication Binary folder.

After finishing flashing, be sure to remove the SOP2 jumper in order to run the ob-board application.

GUI Version

The GUI tool provides a user friendly interface to use the radio tool.

You have three types of devices for connection:

  • CC3100 SPI
    • Note: This is not recommended to use because you can only connect to one CC3100 board with this protocol, if more than one CC3100 is present. CC3100 UART is the recommended connection.
  • CC3100 UART
  • CC3200 UART

With UART connection type selected, you can pick from a list of known COM port and baudrates. Click on the blue spinning arrows on the right to refresh the list if you don't see the COM port showing up. If you still don't see your port showing up, please check your device connection and make sure you have the latest FTDI profile flashed. See CC31xx & CC32xx FTDI Flashing for details.

Upon a successful connection, the Details box on the left will tell you detailed device information on the connected device. This is a good chance to make sure you board is flashed with a desired image version.

FW Ver. (or Firmware version), is arranged in the following way: <NWP version>.<FW version>.<PHY version>

The CC3200 App Ver. information is only for CC3200, indicating the application version flashed onto the device.

The only baud rate supported right now is 115200.

TX Testing

There are three types of TX testings supported:

Packetized Each packet is sent one at a time from the application MCU to the network processor. There is a large delay between packets in this mode. Generally used for RF evaluation.
Continuous This is a test mode where the network processor sends out packets back to back in an internal loop, without the intervention of host MCU. The delay between packets is typically very small and hence useful for FCC/ETSI certification purposes where high duty cycle is required. Only used for emission Certification.
CW (Carrier Wave) In this mode the device transmits an un-modulated RF tone. The frequencies can be selected in steps of 312.5Khz. Note that the power output with tone 0 is very low. Incase higher RF power is desired use tone numbers other than 0.

Some fields will be disabled/enabled, depending on the testing type you want to run. For example, Amount will only be disabled when Continuous testing type is selected.

Parameter explanation:

Parameter Range (inclusive) Description
Rate 802.11 PHY Data Rate
Channel [1, 13] 802.11 2.4GHz band WiFi channel. 14 is not supported
Data Pattern
Preamble [Long, Short] OFDM preamble is automatically configured bt the device when OFDM rates are selected.
Power level [0-15] 0 being the maximum power and 15 being the minimum power.
Override CCA [Yes, No] Enable this field for CCA (Clear Channel Assessment) override if the WiFi environment is too congested to have a reliable periodic transmission.
Size [24, 1400] Packet size, in Bytes
Tone [-25, 25] CW only. 0 means tone at center frequency. A value N between within the range [-25, 25] means tone at offset N*312.5kHz.
Delay [100, 1000000] Delay of transmission, in milliseconds (mSec).
Amount [0, 4294967290] Number of packets to transmit. A value of 0 indicates infinite number of packets.
Destination MAC address The destination MAC address in packets.

RX Testing

The RX Testing is used for gathering WiFi statistics in the air within a specified channel.

  • Duration

Statistics gathering time can be specified with a fixed duration, or 0 to make the testing time indefinite, until user presses the STOP button to stop. Statistics will be gathered automatically whenever a RX testing is stopped. However, users may choose to gather the statistics any time before RX testing ends by clicking the button Get Statistics.

Fields explanation:

Addr Mismatch Packets with address mismatch
FCS Error Frame Check Sequence error
mang frame Average RSSI in management frames
other frame Average RSSI in other frames

Insertion Loss calibration

The TX power levels and Rx sensitivity numbers quoted in the datasheet are at the device RF pin. Additional loses due to onboard filter, PCB trace, connectors and cables used to connect to the external equipment should be accounted for seperatly by adding their insertion losses.

On the TI EVMs the onboard filter insertion loss is typically 1dB (max of 1.35dB), the PCB trace + RF connector loss is ~0.4 dB. These need to be accounted for while evaluating the performance. Incase the user has a different filter or a different trace on their PCB the user needs to measure their insertion loss seperatly. The insertion loss of the cable used to connect the EVM to the external equipment can be measured using a network analyzer.

CLI Version

The CLI tool provides a traditional command line version of the radio tool. This is particularly useful when performing large scale automated testings. The RadioToolCLI.exe application is located at the RadioToolApplication directory. Use CMD or batch files to execute commands.

Hardware connections on Non TI EVMs

In order to use the RadioTool on a platform other than TI EVMs the interface signals from the Emulation board can be wired to the corresponding pins on the custom platform. Note that the signal voltage level from the Emulation board LaunchPad is 3.3V and the VCC level is 3.3V. This VCC can also be used to power the 3X00 device on the custom platform. Make sure the IO voltage levels between the emulation board and the device on the EVM and same.

Appendix A: APIs for Accessing Library Functions

From this point and on contains information about utilizing the radio tool source and library. You may stop here if you just want to use the radio tool as it is.

The followings are the API functions used in the Radio Tool library files. You may access the three library files (CC3100Lib.dll, CC3100LibUART.dll, and CC3200Lib.dll) directly without the use of Radio Tool GUI application for your own tool development.

Appendix B: Source Code For Developers

Source codes of the radio tool can be found in the installtion location. You'll need:

  • Visaul Studio (2010 SP1 minimum)
  • Full-featured IAR Workbench for ARM (please check with your SDK version for a proper IAR version to use)
