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

What to do if I need to use RTC as timer each time I receive event ?  All this code ? :

 RTC_Start(); 

RTC_SetDateAndTime ....

RTC_SetAlarmHandler(AlarmIsrHandler);

.

Hi,

i am stuck using pir sensor on Psoc4 BLE, I've found a documentation explaining how to use pir on psoc family, and set the necessary circuit to obtain low-pass and high-pass filter as external. Datasheet says that i need 2 opamps to amplify signal coming from sensor, and 2 opamps for comparing(even if 2 opamps are available for psoc4 ble, i've tried to make that circuit) . I also use adc and drive led with pwm for observing voltage change depends on movement. I may have some wrong points about using gpio pins. I am not sure and cannot understand which step is wrong. My circuit is not working. I am sharing my project file and circuit picture. I know circuit is so complicated to figure it out; but you may give me a clue about my wrong. I am looking forward to hearing your response.

Note: Circuit in DSC_0516 and 0517, resistors i used at above are for amplfication with opams, te other ones are for filter operations.

Hello,

I cannot get CYBLE-014008-00 Deep Sleep Current to correct level. Datasheet specifies 1.3 uA current for Deep Sleep Mode.

Here is one setup that I have tested:

-CYBLE-14008-EVAL connected to CY8CKIT-42 BLE Pioneer Board.

-Following application programmed

    

#include <project.h>
int main(void)
{
    CySysPmDeepSleep();
    //CySysPmHibernate();
    
}

   

-CYBLE-14008-EVAL removed from CY8CKIT-42 BLE Pioneer Board.

-Power supplied to CYBLE-14008-EVAL board (J1 pins 23 and 24)

-Current is measured from power supply

As a result I am getting currents of 1.1 - 1.3 mA

If I comment out CySysPmDeepSleep() and enable CySysPmHibernate() Current goes to specified levels of Hibernate mode.

I have set debug pins to GPIO-mode from PSOC-Creator. 

Could somebody help me to get Sleep current to specified level?
