We are using a CYBLE-022001-00 module and I need 2 ADC SAR on the design. However, when I perform a build the error indicates 2 clocks are required and 1 is available.

Any way around this?

I am not sure about how this works. I have never tried to run a program with BLE before I think.

I have a program which I have to update. I modify some things (nothing related with ble behaviour). things like: now this sketch controls 5 motors and it has to control 10, not i has 2 force sensors and it has to control 3... This kind of stuff. BLE file is almost equal.  I just add notifications for new variables.

I have a problem when I try to run the program in my pioneer development board (ble version). It hangs and gives an error:

"Debugger exited unexpectedly during run. Encountered error (Target disconnected See output window for more information.)"

Clicking over Show more details" gives:

"There was an unhandled error during the debug session. This has forced the debugger to shutdown. Try again."

I am testing it without anything connected. Just to see if it works. So maybe this is the problem and I need to connect everything to make it working.

As soon as main function starts, InitializeSystem is called:

void InitializeSystem(void)
{
    CyGlobalIntEnable;                //Activate mask of interrupts
    CyBle_Start(CustomEventHandler);  //Init BLE and set event handler function
    ADC_IRQ_StartEx(ADC_ISR);         //Interrupt for reading ADC
    isr_button_StartEx(MyISR);
    /*Set vector for WDT interrupt to desired function. This function will be in charge of updating values to be sent by BLE*/
    CyIntSetVector(WATCHDOG_INT_VEC_NUM, &WDT_INT_Handler); 
    InitializeWatchdog();
    OPA_Start();                     //Start OPA
    OPA_Enable();
    ADC_Start();                     //Start ADC
    ADC_StartConvert();
    //CyDelay(1000);
}

I have read on other post about in the latest version of BLE watchdog is not used. It is used something called BLESS??. Maybe this is the problem. The current version of my software was built with an older version of PSOC and components. And now I updated the whole project to the latest one.

My problem is that if I set watchdog as active (in Initialize function), that function never ends. And in case it does, something goes wrong and it crashes.

I would want the code to reach this line in main():

for(;;) {       
        CyBle_ProcessEvents();

        ...

I am developing a pcb to keep all my stuff there but unitl I have it printed, I have to test my code in this board.

Hello, 

can me somebody help with uart - speed?

When I set up the speed of uart to 19200bd, all is ok.

When I set up the speed of uart to 115200, I have a problem with receiving the characters.  When I send characters from PC, uart interrupt detects twice more character.

For example:

Send from PC: HELLO

Receive in processor: H, null,E,null,L,null,L, null, O, null. Between characters is received the character: 0 (dec). I use the interrupt:RX FIFO not empty.

But in 19200bd, processor does not receive the character 0(dec).

The uart actual speed is 115196bd  (The CLK of processor is 48MHz). 

I tried to change Oversampling, CLK of processor, Stop bits, but everything does not work. 

Thank you for help:)

I have been using CYBL10161-56LQXI where currently I am working over the BLE v4.2.
I have a question about the data that we store in CYBLE_EVT_GATTC_HANDLE_VALUE_NTF. 

What I know till now is about CyBle_GattsNotification() that it is a non-blocking function and what it does. 
I have save the data to be sent to the client over, CYBLE_GATTS_HANDLE_VALUE_NTF_T  my_variable; // my declaration
 

and  in some function this is what I use,
 my_variable.value.val           = MyData;
 my_variable.value.actualLen = length;
 my_variable.value.len           = length;
 my_variable.attrHandle         = charAttrHandle;
So, my question is, do we need the memory that we are using to set up the descriptor(my_variable)  to exist after my call returns? As right now I am saving it on the stack, which means at some point I am going to lose it.

In single channel mode for the SAR_ADC, ( psoc 4m ), the max value appears to be 2047.  This is a 11 bit value.  It looks like the a/d is still acting like the a/d is running in differential mode, ie -2047 to 2047.  Sometime the ground measurement returns -1, which seems to indicate that a differential mode measurement is returned.

Is there a way to have the A/D return 0 to 4095, which is a 12 bit a/d range.
