What is the difference between CYBLE_EVT_GAP_DEVICE_CONNECTED and CYBLE_EVT_GATT_CONNECT_IND (and their disconnect's)?

For me it seems natural to use the GAP event to see if an connection is created (or not) since the Generic Access Profile is about connections. But I've seen that some of the example projects from Cypress uses the GATT variant.

I continuous send 256Bytes to the phone in the notification mode.A packet is 20bytes and last packet is 16bytes.But the test failed,Only we can get three packets on the phone.The code stopped in this line: 

    while(CyBle_GattGetBusyStatus() == CYBLE_STACK_STATE_BUSY); 

On the other hand,What is the maximum number of packets that CYBLE could process per connection event in  notification mode?

thanks.

I am evaluating the CY5676A PRoC BLE 256KB Module in HCI mode. I am trying to use the data length procedure.

If I use the command with values different to the min and max of the range (0x1b and 0xFB) the command complete event returns an error. In the command the TxTime is set to the duration of the packet depending of the data length requested.

Is it possible to select a data size different than 27 and 251?

For some reason this code gets stuck at sprintf in debug mode. Any tips? 

#include <project.h>
#include <stdio.h>

int main()
{
    CyGlobalIntEnable; /* Enable global interrupts. */
 
    UART_Start();
    
    char* str;
    sprintf(str, "Hello");

    for(;;)
    {
        UART_UartPutString(str);
    }
}

What a difference between Type "uint8[] " and  "uint8 array" in Custom Characteristic Field  of BLE?

And how to assign array type " uint8[] [] " ?

Hi,

I'm trying to program PSoC board as HID client. I am sending by UART some messages to PC to know what is goings-on. I have an event HCI Status and code number 4. It is page timeout. What am I doing wrong?

I am using CY8CKIT-042-BLE. PRoC module has program from example HID-Keyboard and I have connection by BLE between those modules. I have this error after trying to connect.

Events I have got in terminal:

CYBLE_EVT_STACK_ON
CYBLE_EVT_GAPC_SCAN_START
CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT
CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT
CYBLE_EVT_GAPC_SCAN_STOP
CYBLE_EVT_HCI_STATUS: 4
CYBLE_EVT_GATT_CONNECT_IND
CYBLE_EVT_GAP_DEVICE_CONNECTED
