Hi,

How to know if the BLE device is scanning in FAST mode or SLOW mode? In fact, for my particular case, I would like to know when exactly the device is advertising to blink a LED at the same rate.

Thanks,

Denis Alain, Eng.

hello,

I can not change the maximum number attached to my device.

I do not want to do the pairing for each connection

see file BLE_StackGap.h

We are using the CYBLE-022001-00 module in a project and need to send some commands to another device via the I2c bus. Is anyone aware of a sample project that covers this application?

I want to send single advertisement packet on particular event (data from serial interface) without entering Deep Sleep mode, In Project #009: Dynamic Broadcaster I use CyBle_GappStopAdvertisement() to stop advertisement (see code below). However, when I call CyBle_GappStartAdvertisement(CYBLE_ADVERTISING_FAST) it seems to be ignored. Why CyBle_GappStartAdvertisement(uint8 advertisingIntervalType) doesn't work?

int main()
{

    InitializeSystem();

    UART_1_Start();

    for(;;)
    {
        CyBle_ProcessEvents();

        rxData = UART_1_UartGetChar();
        if (rxData)
        {
            CyBle_GappStartAdvertisement(CYBLE_ADVERTISING_FAST);   
        }
        else
            CyBle_GappStopAdvertisement();

#if ENABLE_DYNAMIC_ADV       
        DynamicADVPayloadUpdate(rxData);
#endif

    }
}

Hello,

I'm using CY8CMBR3116 CapSense controller in my project. HI is configured on pin23 (SPO0), CSx pins also - related to connected buttons. 
In datasheet p.15 it is described that HI should be enabled in every change of CSx.

How it should be (according to datasheet)
On button activation HI goes low for THI after this time back to high,
on release goes low for THI after this time back to high. (Figure 10)

How it works
On button activation HI goes low and stays as long as button is pressed.
It will go high only on release.
 

Because of this it is not possible to detect action on other button (without pooling) while other is pressed.
I couldn't find any description how to use it like in datasheet and also I couldn't find anything to configure in register map.

So where is the problem, hardware or missing configuration?

Thanks.

Hello,

we try to connect from cyble-022001-00  to 3 or 4  cyble-022001-00 successively.

First : we build a array ( TONOFFC [][] ) with the mac addresses we want to connect to.       

Second : we read the address in the array and setup the peer address after that we connect.

Third  : We disconnect the ble . This code is managed in other condition because that doesn't work if it is in the previous condition.

See below a part of our code :

Main ()

{

......

while (1)

....

{
            peerAddr.bdAddr[0]=TONOFFC[intTest][5];
            peerAddr.bdAddr[1]=TONOFFC[intTest][4];
            peerAddr.bdAddr[2]=TONOFFC[intTest][3];  
            peerAddr.bdAddr[3]=TONOFFC[intTest][2];  
            peerAddr.bdAddr[4]=TONOFFC[intTest][1];   
            peerAddr.bdAddr[5]=TONOFFC[intTest][0];
            peerAddr.type  = 0;
            CyBle_GapcConnectDevice(&peerAddr);
            CyBle_ProcessEvents();          
            }

     if(state==CONNECTED )
    {
        CyBle_GapDisconnect(cyBle_connHandle.bdHandle);  
        state=DISCONNECTED;
        CyDelay(200u);
        CyBle_ProcessEvents();  

    }

}

Result :

For the moment only the first device of the array is working. the while loop works correctly because each variable change.

But there is no connection to the second , third ... devices.

If somebody have any idea , please help us.

Nota : We already use this code for connect one cyble-022001-00 to another one and it works fine.

Can i use  LE Generate DHKey Command  for CY5676A PRoC BLE 256KB Module in HCI mode ?

Because i get the status 'Unknown HCI Command' :
