Compiler/CC3220SF-LAUNCHXL: alternative for TxFramesCount

Tool/software: TI C/C++ Compiler

Hi,

In the latest SDK (simplelink_cc32xx_sdk_4_10_00_07) SlDeviceGetPmStatClrOnRdTypes_t structure is available to get following parameters.

typedef struct
{
    _u32 Disconnects;         // clear on read - disconnect count
    _u32 TxFramesCount;       // clear on read - Tx Frame count
    _u32 ReceivedBytesCount;  // clear on read
    _u32 reserved[4];         // reserved for additional clear on read statistics
}SlDeviceGetPmStatClrOnRdTypes_t;

Currently I am using Old SDK version (v2_10_00_04), To upgrade to the latest takes some more time.

So for time being is there any alternative API/ Structure to get the above parameters from the SDK version (v2_10_00_04)?

Suresh

Hi Jan D,

Thanks for your reply.

I wanted to fetch the AvarageMgMntRssi(RSSI) value from SlWlanGetRxStatResponse_t structure.

Hardly i am getting the correct value once out of 10 times. Following piece of code also won't support for SDK version (v2_10_00_04), or am I missing something?

void RxStatCollectTwice()
{
    SlWlanGetRxStatResponse_t rxStat;
    _i16 rawSocket;
    _i8 DataFrame[200];
    struct SlTimeval_t timeval;
    timeval.tv_sec =  0;             // Seconds
    timeval.tv_usec = 20000;         // Microseconds. 10000 microseconds resolution
    _u32    status;

    sl_WlanRxStatStart();  // set statistics mode

    rawSocket = sl_Socket(SL_AF_RF, SL_SOCK_RAW, 0);
    // set timeout - in case we have no activity for the specified channel
    sl_SetSockOpt(rawSocket,SL_SOL_SOCKET,SL_SO_RCVTIMEO, &timeval, sizeof(timeval));    // Enable receive timeout
    status = sl_Recv(rawSocket, DataFrame, sizeof(DataFrame), 0);

    usleep(1000); // sleep for 1 sec
    status = sl_WlanRxStatGet(&rxStat, 0);
    usleep(1000); // sleep for 1 sec
    status = sl_WlanRxStatGet(&rxStat, 0);

    if (status == 0) 
    {
        if (rxStat.AvarageMgMntRssi != 0) 
        {
            IotLogInfo("RSSI %d", rxStat.AvarageMgMntRssi);
        }
        else 
        {
            IotLogInfo("getting RSSI -99");
        }

    }
}

Suresh

Hi Suresh,

What do you mean that you are not able get correct RSSI value? What exactly do you need? You need RSSI value at transceiver mode or connected mode?

I am not 100% sure, but I think that AvarageMgMntRssi value is not valid in transceiver mode. In transceiver mode (SL_AF_RF) is RF PHY forwarded to your application code and I think device MAC/NWP cannot determine between data and management packets because is bypassed.
I use AvarageMgMntRssi at connected mode (STA mode) and it works well. But it not make sense to call this API fastest then at 5 sec interval. At 1sec interval you will not get proper values definitely. In case of connected mode and using AvarageMgMntRssi or AvarageDataCtrlRssi is not mandatory call sl_WlanRxStatStart() and sl_WlanRxStatStop() API.

btw1 ... this part code:

IotLogInfo("getting RSSI -99");

does not mean RSSI value -99 but than RSSI value is not available now.

btw2 ... if you need RSSI value to your AP, you can use network scan as well.
