CC2340R5: TX power configuration in basic ble

Hi,

Thank you for reaching out to us. We will look into your question and get back to you as soon as possible. In the meantime, can you provide us with the SDK version you are using as well as which example you are working on?

Best Regards,

Hi,

We are currently working to find a workaround for this issue but it seems that basic_ble does not take radio/power sysconfig setting yet.

You can change the power directly by calling the following HCI command: HCI_EXT_SetTxPowerDbmCmd()

The function is located in hci.h file.

regards,

HCI_EXT_SetTxPowerDbmCmd(8,0)

NO impact on power

Hi,

Where do you call the HCI command?

What is your test to evaluate the Txpower? Which tool are you using for the test?

Let's show me where the command is called.

{
const int8_t txPower = 4;
const uint8_t fraction = 0;
HCI_EXT_SetTxPowerDbmCmd(txPower, fraction);
}

regards,

Tool - spectrum analyzer

Hi,

prefer to call it just after the advertisement initialization: in the function peripheral_start() located in app_peripheral.c file

 status = BLEAppUtil_initAdvSet(&peripheralAdvHandle_1, &advSetInitParamsSet_1);
    if(status != SUCCESS)
    {
        // Return status value
        return(status);
    }

status = HCI_EXT_SetTxPowerDbmCmd(txPower, fraction);
if(status != SUCCESS)
{
   // Return status value
   return(status);
}

Let me know if it works,

Thanks and regards,

Hi,

My apologies. we have also troubles with this command. Thanks for the report, the issue is now in good hands and our R&D is working on this to provide a workaround ASAP.

From my side I'm searching for a patch, from your side is this a production-stop level issue?

regards,

Yes Production level issue
