Hi Everyone...I need your help.

I want to implement a Passive Scan Mode using WICED 3.1.1.

So I changed codes as blow

before..

wwd_wifi_scan( WICED_SCAN_TYPE_ACTIVE..

after

wwd_wifi_scan( WICED_SCAN_TYPE_PASSIVE...

But...I think it's not operate as passive scan mode yet..

Please Let me know what i miss..?

Thansks.

Hi,

I am testing a modified tcp_server snip I have configured the device as WICED_AP_INTERFACE. While the connected client sends a TCP packet every 1ms, after some time (in a period of 10 seconds) the application hangs up. You cant even connect to the access point anymore. No Hard fault or error message is received, the rest of my application is still running fine.

Here is the simplified source for demonstartion:

static void tcp_server_thread_main(uint32_t arg)
{
    tcp_server_handle_t* server = (tcp_server_handle_t*) arg;


    while ( quit != WICED_TRUE )
    {
        wiced_packet_t* temp_packet = NULL;


        /* Wait for a connection */
        wiced_result_t result = wiced_tcp_accept( &server->socket );


#ifdef TCP_KEEPALIVE_ENABLED
        result = wiced_tcp_enable_keepalive(&server->socket, TCP_SERVER_KEEP_ALIVE_INTERVAL, TCP_SERVER_KEEP_ALIVE_PROBES, TCP_SERVER_KEEP_ALIVE_TIME );
        if( result != WICED_SUCCESS )
        {
        uartDebugString(("Keep alive initialization failed \r\n"));
        }
#endif /* TCP_KEEPALIVE_ENABLED */


        if ( result == WICED_SUCCESS )
        {
            /* Receive the query from the TCP client */
            if (wiced_tcp_receive( &server->socket, &temp_packet, WICED_WAIT_FOREVER ) == WICED_SUCCESS)
            {
                /* Process the client request */
                tcp_server_process( server, temp_packet );


                /* Delete the packet, we're done with it */
                wiced_packet_delete( temp_packet );


#ifdef TCP_KEEPALIVE_ENABLED
                uartDebugString(("Waiting for data on a socket\r\n"));
                /* Check keepalive: wait to see whether the keepalive protocol has commenced */
                /* This is achieved by waiting forever for a packet to be received on the TCP connection*/
                while(1)
                {
                     if (wiced_tcp_receive( &server->socket, &temp_packet, WICED_WAIT_FOREVER ) == WICED_SUCCESS)
                     {
                           tcp_server_process( server, temp_packet );
                           /* Release the packet, we don't need it any more */
                           wiced_packet_delete( temp_packet );
                     }
                     else
                     {
                           uartDebugString(("Connection has been dropped by networking stack\r\n\r\n"));
                           break;
                     }
                }
#endif /* TCP_KEEPALIVE_ENABLED */
            }
            else
            {
                /* Send failed or connection has been lost, close the existing connection and */
                /* get ready to accept the next one */
                wiced_tcp_disconnect( &server->socket );
            }
        }
    }
    uartDebugString(("Disconnect\r\n"));
    wiced_tcp_disconnect( &server->socket );
    WICED_END_OF_THREAD(tcp_thread);
}



static wiced_result_t tcp_server_process(  tcp_server_handle_t* server, wiced_packet_t* rx_packet )
{
    char*           request;
    uint16_t        request_length;
    uint16_t        available_data_length;
    wiced_packet_t* tx_packet;
    char*           tx_data;
    char dbg[64];


    wiced_packet_get_data( rx_packet, 0, (uint8_t**) &request, &request_length, &available_data_length );


    /* Null terminate the received string */
    request[request_length] = '\x0';
  
    /* Send echo back */
    if (wiced_packet_create_tcp(&server->socket, TCP_PACKET_MAX_DATA_LENGTH, &tx_packet, (uint8_t**)&tx_data, &available_data_length) != WICED_SUCCESS)
    {
    uartDebugString(("TCP packet creation failed\r\n"));
        return WICED_ERROR;
    }


    /* Write the message into tx_data"  */
    tx_data[request_length] = '\x0';
    memcpy(tx_data, request, request_length);


    /* Set the end of the data portion */
    wiced_packet_set_data_end(tx_packet, (uint8_t*)tx_data + request_length);


    /* Send the TCP packet */
    if (wiced_tcp_send_packet(&server->socket, tx_packet) != WICED_SUCCESS)
    {
    uartDebugString(("TCP packet send failed\r\n"));


        /* Delete packet, since the send failed */
        wiced_packet_delete(tx_packet);


        server->quit=WICED_TRUE;
        return WICED_ERROR;
    }
    uartDebugString(("Echo data: %s\r\n"));
    return WICED_SUCCESS;
}

I am using: Wiced SDK 2.4.1 + LwIP + FreeRTOS.

I also tried the tcp_server_async snipped with the same results.

Is this a known issue? At this point of our development it would be expensive to change to the newer SDK. Would the SDK 3.x solve this?

Recently ran into a problem after migrating to 3.1.0 from 2.4.1

When WICED_DISABLE_MCU_POWERSAVE is defined, power-cycling the board will bring it into a state shown below:

Starting WICED v3.1.0

Platform BCM943362WCD4 initialised

Started ThreadX v5.6

Initialising NetX v5.7_sp1

Creating Packet pools

Could not set AMPDU parameters

Error 2 while starting WICED!

The application used is snip/apsta (same behaviour on other applications)

I am not sure whether this is related to platform restructuring in 3.1.0, and whether this is intentional/intended behaviour. My suspicion comes from the following statement in WICED/WWD/internal/chips/43362A2/wwd_ap.c:

     "For SDK 3.0, and beyond, each chip will need it's own function for setting AMPDU parameters."

Any ideas, tips, or pointers to better understand the problem and why it's behaving this way is greatly appreciated.

Hi,

I was trying to implement IR decoder for decoding the ac remote control signals on ISM43362_M3G using wiced. I was facing some difficulties.It would be really helpful if someone can help me out in figuring what is the problem or if they can share their own implemetation.

I have also attached my code below.

Hello,

I would like to create a proof of concept based on WICED WIFI. I have some WICED1 boards that I can use for prototyping and if all goes well I will use the latest board design before going to the next level but as I said I would like to come up with a proof of concept this week so using what I have on hand would save me time.

Thanks very much,

Gil
