CC2640R2F: Crash in event after while

Hello Vahid Javadi,

I hope you are well. To investigate further could you provide what SDK (version) you are using, as well as CCS version, and what example you are experiencing a problem with (and if you modified code within it).  Are you using a custom board, or the evaluation board?

Did you try to place breakpoints in the code, and step through to see what's going wrong? 

For resources to look into to get familiar with RTOS:

Reference: adcbufcontinuous readme

Reference: ADCBufCC26XX.h File Reference (ti.com) 

Reference: BLE-Stack Debugging Guide (ti.com)

Hello Alex 

Thanks for your answer. i use simple_peripheral example with ccs 12.4.0.00007 and SDK version is 5_30_00_03 . I found out this function crash the event and in second period just one adc value change : 

ADCBuf_Params_init(&adcparams);
adcparams.returnMode = ADCBuf_RETURN_MODE_BLOCKING;
adcparams.recurrenceMode = ADCBuf_RECURRENCE_MODE_ONE_SHOT;
adcparams.samplingFrequency = 200000;
MyAdcBuf = ADCBuf_open(Board_ADCBUF0, &adcparams);

conversion.samplesRequestedCount = 250;
conversion.sampleBuffer = sampleBuffer1;
conversion.adcChannel = 1;

static void detectLongPeaks(uint16_t size, uint16_t threshold, uint16_t minWidth) {
	static int peakStart = -1,n=0;
    static uint16_t peakWidth = 0;
    static  uint16_t maxPeak=0;
    static uint16_t maxPeakLocation=0;
	static uint16_t j=0,i;
	maxPeakLocation=0;
	maxPeak=0;
	peakWidth = 0;
	j=0;
	peakStart = -1;
	memset((uint16*)PeakTimeDiff,0,250);
    for (i = 10; i < size; i++) {
        if (adcbuf[i] > threshold) {
            if (peakStart == -1 && (adcbuf[i]-threshold)>30 && (adcbuf[i]-adcbuf[i-1])>20) {
                peakStart = i;
                peakWidth = 1;
                maxPeak=adcbuf[i];
                maxPeakLocation=i;
                UART_write(uart,"[ ", 2);
            }else if(peakStart != -1 && (maxPeak-sampleBuffer1[i])>30)
            {
            	  PeakTimeDiff[j++]=maxPeakLocation;
            	  peakStart = -1;
            	  peakWidth = 0;
            	  maxPeakLocation=0;
            	  maxPeak=0;
            	 UART_write(uart,"] ", 2);

            }else {
                peakWidth++;
                if(adcbuf[i]>maxPeak)
                {
                	 maxPeak=adcbuf[i];
                	 maxPeakLocation=i;
                }
            }
        } else {
            if (peakStart != -1) {
            	PeakTimeDiff[j++]=maxPeakLocation;
            	  peakStart = -1;
            	  peakWidth = 0;
            	  maxPeakLocation=0;
            	  maxPeak=0;
            	  UART_write(uart,"] ", 2);
            }

        }
        n = sprintf (cc_uart_send_buffer, "%.2d  ", adcbuf[i]);

     	UART_write(uart,(uint8*)cc_uart_send_buffer, n);

    }

    if (peakStart != -1 && peakWidth >= minWidth)
    {
    	PeakTimeDiff[j++]=maxPeakLocation;
    }
   UART_write(uart,"\r\n", 2);
}

I found out the problem because of stack overflow . how can i select true size of stack . after increase it to 1300 . bluetooth side dont work

Hello Vahid Javadi,

When you changed the stack size did you change "#define SP_TASK_STACK_SIZE" in simple_peripheral.c? I increased the value from 644 to 1300, and was able to connect to the device using my Android S21 FE phone (using BLE Scanner, default example). It seems like your detectLongPeaks is custom code you have added to the project, did you step through the function and confirm what line causes the crash?

Thanks,
Alex F 

Hello alex , after increase stack  to 1100 code work very well but bluethooth no start  and when increase to 1200 code dont start . and when set to 960 bluethooth start but adc read one time . i have 4 event did i problem in event id ???

Hello Vahid Javadi,

When you mention event, which specific one are you talking about? 

Can you provide the results/findings of your custom code and or functions, or other changes you may have made by entering in debugging mode, and placing breakpoints at your custom code or functions to confirm they are, or are not the issue? 

I tested the ble5_simple_peripheral_cc2640r2lp_app project example provided by the SDK, changed the stack size to 1100, and 1200; in both cases I was still able see Bluetooth, and connect to the device. 

Thanks,
Alex F
