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

Hi Sama,

There are two possible issue while merging two sample projects.

1. sdk_config.h flags are not present or enable

- Try to compare the sdk_config.h files of both the projects and add the missing flags. Once compared and updated all the configurations from ble-app-uart example into the saadc example check if errors are reduced.

2. Library path is not added into build configuration

- Fir that compare library paths and add if absent

 In my experience it is always easy to add code from peripheral examples into ble examples. If nothing is working try to add code from saadc example into ble-app-uart example, very less configuration is required in project to add peripherals.

Hi

Thank you for your reply.

I compared the sdk_config.h files of both the projects and added every line which there is not in the sdk_config of SADDC.

I compared the flash placement file and found that something there is not in the flash placement of the SADDC project, so I added them. 

the number of errors reduced but finally, I faced with these errors:

Output/Release/Obj/saadc_pca10056/main.o: in function `ble_evt_handler':

this is the log:

Is there any solution?

I have to add UART to SAADC as my boss wants.

I have wasted a great deal of time to do this task.

Please help.

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.

Update:

I followed the lines of the app error weak file and found out that when the program reaches the line: switch (id) and I press the play button it jumps to line 100 (NRF_BREAKPOINT_COND).

I tried some suggestion in the devzone, including 

https://devzone.nordicsemi.com/f/nordic-q-a/64963/app_error_fault_handler-id-0x00004001-pc-0x0003290b-app_error_handler-sdk-v17-nrf2840-pdk

https://devzone.nordicsemi.com/f/nordic-q-a/65483/softdevice-assertion-failed-after-using-fds_gc/267757#267757

I also edit the section placement macro as below due to SoftDevice present. However, it does not make a difference.

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x100000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x40000

FLASH_START=0x27000

FLASH_SIZE=0xd9000

RAM_START=0x20002ae8

RAM_SIZE=0x3d518

I could not find a solution.

Please help.

I look forward to hearing from you.

Hi,

BLE applications requires a certain method when debugging them. You can't resume an application after you have halted it. You'll have to restart it instead. It's explained more in detail here.

Can you use this method and see how far the program reaches this time?

regards

Jared

Hi,

Thank you for your reply. 

Sorry, but It is not mentioned where should I change the PRIMASK bit in my registers list. 

As I found out a CPU register containing this bit, but which register and which bit has been assigned?

I wonder why important details do not explain anywhere. It is really time-consuming to find these details.

I look forward to hearing from you.

Thanks,

Sama

[Sama]

Hi,

I added the following code to set PRIMASK bit, as suggested in this post (https://devzone.nordicsemi.com/f/nordic-q-a/477/can-i-debug-ble-program)

But this does not make any difference as you can see.

When I select the first line in the active call frame on the top page as below

It jumps in this part.

Is there any clue to find the problem?

Br,

Sama

Hello! Sama:

I think your code is okay.

Your code is trap in error handle function.Because of sleep mode is running when your advertising timeout during debug mode. The real board without USB J-Link will be not halt in break-point. And the system will be reset when you wake up by external GPIO. It's the normal case in BLE UART example.

static void on_adv_evt(ble_adv_evt_t ble_adv_evt)
{
uint32_t err_code;

switch (ble_adv_evt)
{
case BLE_ADV_EVT_FAST:
err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING);
APP_ERROR_CHECK(err_code);
break;
case BLE_ADV_EVT_IDLE:
sleep_mode_enter();  //If you want to try prevent halt in debug mode....Change this function with normal mode or else.
break;
default:
break;
}
}

[Sama]

Hello Henry,

Thank you for your reply.

I will try it and inform you about that.

Sama

Update:

I comment out the line (sleep_mode_enter()), but this does not make any difference.

It is disappointing that it is so hard to find the error.

 Does it reach the breakpoint at log_init()? Earlier you wrote that it calls the error handler from ble_stack_init(). Exactly from where in ble_stack_init() is it called from?
