WICED Studio Wi-Fi Combo

New Contributor

Hello,

I want to send data from one PSoC to another every 5 or 10 sec. The model of my kits is PSoC 6 CY8CKIT_062 WiFi-BT Pioneer Kit. I have the following code in my application_start().

    char buff2[10];

    uint16_t light_output;

    float mv2;

    wiced_init( );

    wiced_rtos_init_queue(&paddleQueue,"paddleQueue",sizeof(game_msg_t),10);

    game_msg_t msg;

    wiced_bt_gatt_status_t write_status;

    wiced_adc_init(WICED_ADC_1,5);

    wiced_rtos_pop_from_queue(&paddleQueue,&msg,WICED_WAIT_FOREVER);

    while(1){

        wiced_bt_gatt_value_t *p_write = ( wiced_bt_gatt_value_t* )malloc( sizeof( wiced_bt_gatt_value_t ) + 1 );

        WPRINT_APP_INFO(("Light(mv): "));

        wiced_adc_take_sample(WICED_ADC_1, &light_output);

        mv2 = (light_output*3300)/4096;

        sprintf( buff2,"%f",mv2);

        WPRINT_APP_INFO( ( buff2));

        (p_write)->handle   = 0x002A; /* hard coded server ccd */

        (p_write)->offset   = 0;

        (p_write)->len      = 1;

        (p_write)->auth_req = GATT_AUTH_REQ_NONE;

        (p_write)->value[0] = (uint8_t)(mv2);

        //(&p_write)->value[1] = 0x08;

        write_status = wiced_bt_gatt_send_write ( msg.val, GATT_WRITE_NO_RSP, p_write);

        WPRINT_APP_INFO(( "write_status: %d\n", write_status));

        CyDelay(5000);

        free( p_write );

    }

What this code does is that it waits "msg" to come from another thread. After "msg" comes, it is popped from the queue. Then, every 5 seconds "mv2" is sent to the other kit. However, I can send "mv2" only 7-10 times. After that, the other PSoC crashes (does not receive "mv2" anymore). The PSoC that sends "mv2" also crashes and gives Unhandled bluetooth event 5. The type of this event is wiced_bt_gatt_evt_t, and when I go to declaration of wiced_bt_gatt_evt_t, I can see only 0, 1, 2, 3 and 4 as event values. There is no 5. Also, I get "running low on tx buffers" and "getbuf size is too big" errors. How can I solve this issue?

It would be helpful if the BT library also shows the requested size with "getbuf size is too big" error.

Unfortunately, we do not have such API as of now.
