CC3200-LAUNCHXL: is there any way to get the WIFI Signal Strength when the CC3200 is connected with the WIFI Router?

Hi,

How long do you wait after starting the stats collection with sl_WlanRxStatStart() before you check the statistics? If there is very little network traffic, then it may not be possible to generate an RSSI statistic.

What code are you trying to use from the antenna_selection example? It doesn't seem like it uses the sl_WlanRxStat*() APIs. Please try the following code and see if you can get some expected RSSI values:

SlWlanGetRxStatResponse_t RxStat;
sl_WlanRxStatStart();
//add in your platform's wait function here, wait for 15 seconds
//ex
//sleep(15);
sl_WlanRxStatGet(&RxStat,0);
drawRxHist(&RxStat);

void drawRxHist(SlWlanGetRxStatResponse_t *rxStatResp)
{
    float percent;
    uint32_t fraction;
    uint32_t integer;
    int32_t i,j;

    UART_PRINT(
        "\r\n*********************************Rx Statistics"
		"**********************************\r\n");
    UART_PRINT("Received Packets: %d \r\n",
               rxStatResp->ReceivedValidPacketsNumber);
    UART_PRINT(
        "Average RSSI for management: %d Average"
		" RSSI for other packets: %d\r\n\r\n",
        rxStatResp->AvarageMgMntRssi,rxStatResp->AvarageDataCtrlRssi);

    if(rxStatResp->ReceivedValidPacketsNumber == 0)
    {
        UART_PRINT(
            "    -----------------------   no data collected"
			"   -----------------------\r\n");
    }
    else
    {
        UART_PRINT(
            "    -----------------------   RSSI Histogram"
