BOOSTXL-CC3135: Performing SAR Tests

Part Number: BOOSTXL-CC3135
Other Parts Discussed in Thread: CC3135, CC3135MOD, CC31XXEMUBOOST, CC3100, CC3220S, CC3200

Hi,

We are trying to evaluate the CC3135MOD, And we are using the Boost-XL CC3135 evaluation module interfaced to the Host (STM32L4 microcontroller) using SPI lignes.

We have to perform SAR tests for product qualification (Specific Absorption Test).

We found this useful User Guide: SimpleLink™ Wi-Fi® CC3x20, CC3x3x Radio Tool (swru471b) and we thing that contain tests that we have to do.

Unfortunately, we don't have all the required hardware described in this document : CC31xxEMUBOOST neither CC32xx LaunchPad, and in another hand, we want to perform SAR test using our environment (STM32L4 microcontroller, sensor devices .... )

In another part, in the CC32xx SDK, I found this example code named network_terminal under simplelink_cc32xx_sdk_x\examples\rtos\CC3220S_LAUNCHXL\demos\, and we think that is the embedded software that should be flashed on the CC31xxEMUBOOST board to communicate correctly with the CC3100/CC3200 radio tool desktop application.

So, Can we use this code example to perform SAR tests using our Hardware ?

What are the list of function or files needed to do this test ?, note that We have only to do Tx testing and in continuous transmission mode.

Should we only use the entire hardware described in the user guide ?

Regards,

Ghada

    Ghada,

    In case you are not aware, our CC3135 Module Certificatinon Reports can be downloaded from here. And Radio Tool is what was used for certification testing at our test house, so I recommend you also use Radio Tool, which yes, will require a a CC31xxEMUBOOST or CC32xx-LAUNCHXL.

    You mentioned the "CC3100/CC3200 radio tool desktop application". Note that for the CC3135, you'll need to use the CC3xxx Radio Tool version, which can be downloaded from here. Click "Radio Tool Installer for SimpleLink Wi-Fi SDK and SimpleLink SDK Wi-Fi Plug-In" from the table shown on this page.

    On the other hand, you can modify the network terminal example to connect to an AP and send infinite UDP packets. To do this:

    1. In socket_cmd.c for network terminal, modify the function udp_Client() so that when it's looping through sl_Send the condition of while(i <numofPackets) is changed to while(1). This will cause the device to constantly send UDP packets indefinitely.
    2. After you flash the device, open Tera-Term (or equivalent) and connect via the serial port at a baud rate of 115200. 
    3. Perform the following CMD line commands:
      1. Connect to your network by typing (make it a unsecured network):
        1. wlanconnect -s "Name of AP"

        2. Take note of the Gateway AP IP Address

      2. Send packets to the gateway address:
        1. send -c 192.168.1.1 -u

        2. Even though it says it will send 1000 packets, it will send infinitely.

    4. Begin Testing 

    BR,
