adding ble app uart into a peripheral example

[Sama]

Hi,

I am trying to add the ble-app-uart example into the saadc example. I added all needed files.c which there were not in the saadc project and also all paths in the user include path in the project option. I also added all #include needed for the uart example in the main.c file of the saadc project.

I faced a lot of errors such as:

error: 'NRF_SDH_BLE_TOTAL_LINK_COUNT' undeclared here (not in a function); did you mean 'NRF_BLE_GATT_LINK_COUNT

and

error: 'BLE_NUS_BLE_OBSERVER_PRIO' undeclared here (not in a function); did you mean 'APP_BLE_OBSERVER_PRIO'?

and so on...

I tried to add codes into the sdk_config.c to eliminate the errors. But it seems that this is not the correct way.

Could you please help me?

Thank you,

Sama

I added all path of the file I added to the project.
I compare and change the config_sdk manually. I copied lines of the sdk_config of the UART example which there is not int the sdk_config of the SAADC. Does it make a problem?

Thank you

Hi

I noticed that saadc project is non softdevice project where as ble operations are dependent on softdevice. You have to make changes according to that as well.

Again i will recommend to merge saadc into ble example as most of project configurations will be there and working correctly.

finally was able to eliminate the errors and modify the code without any error.

Now, when I send the program on the devkit, it does not advertise. When I debug, it gets stuck in the app_error_weak.c file where the NRF_BREAKPOINT_COND placed, as you can see in the image below.

I searched the error code, but I did not find anything.
Could you please guide me?

What is calling the error handler? How far does the program reach before it enters the error handler? Try setting a couple of breakpoints and see if the program reaches it.

Hi, 

Here is my main function:

int main(void)
{


bool erase_bonds;

// Initialize.
uart_init();
log_init();
timers_init();
buttons_leds_init(&erase_bonds);
power_management_init();
ble_stack_init();
gap_params_init();
gatt_init();
services_init();
advertising_init();
conn_params_init();

uint8_t read_data[64];
long unsigned int Time1,Time2,Time3;
uint32_t err_code = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(err_code);

NRF_LOG_DEFAULT_BACKENDS_INIT();

ret_code_t ret_code = nrf_pwr_mgmt_init();
APP_ERROR_CHECK(ret_code);


saadc_sampling_event_init();
saadc_init();
saadc_sampling_event_enable();

// Start execution.
printf("\r\nUART started.\r\n");
NRF_LOG_INFO("Debug logging for UART over RTT started.");
advertising_start();

while (1) {

Time1=TimeLineFun(0);
//printf("T=%d",Time1);
idle_state_handle();

while ( Counter <= Max_Sample)
{

nrf_delay_ms(1);
TmpCounter = WritePointer-OldWritePointer;
if(TmpCounter<0){
TmpCounter+=LEN_CIRCULAR_BUF;
}

}

Time2=TimeLineFun(1);
//printf("T1=%d," ,Time2);

Time3=TimeLineFun(2);

CalculateParam();

ReadPointer=ReadPointer+(CrossZero*ANALOG_NUM); //in every half_cycle ReadPointer increases the size of CrossZero*ANALOG_NUM
Counter=Counter-(CrossZero*ANALOG_NUM); //in every half_cycle ReadPointer decreases the size of CrossZero*ANALOG_NUM

if((ReadPointer)>=(LEN_CIRCULAR_BUF)) {
ReadPointer=ReadPointer-LEN_CIRCULAR_BUF;
//xil_printf(" ********ReadPointer=%d *********\n\r", ReadPointer);
}
Counter=0;*/

}

/** end *****/

}

/** @} */

I set a breakpoint point for every function. Once it reached the log_init, the program got stuck in the error.

I also comment out the log_init() function, then I debug the program. In this case, the program stays in the ble_stack_init() as you can see below.

I have no idea about this.

What do you think?

Please guide me.
