Hi,

Have you got a look at the documentation ? 
I also created a step by step tutorial here that you may want to follow.

thank u sir. i got it. but now im getting debug error

 app_error_fault_handler(NRF_FAULT_ID_SDK_ERROR, 0, (uint32_t)(&error_info));

now what i can do can u help

[Hung Bui]

Please describe what exact firmware you are debugging. 
Where do you see the error, and what inside error_info. At which step do you get the error. 

[prashanthk]

i am just debugging buttonless ble dfu. and im getting error when debug of program. im getting error in

APP_ERROR_CHECK(err_code);    --->>> here i got runtime error

[Hung Bui]

Please list the step you used for testing. Please try to test the bootloader without the buttonless dfu application first. Made sure you can use the bootloader correctly. 

When you see an error with APP_ERROR_CHECK please check the err_code and check the function that return the err_code to see why it occurred. 

Note that you can set a breakpoint to check for error code, but you can't step the code lines to debug through the code in an application that uses softdevice because the softdevice doesn't work any more after you stopped in a breakpoint.

my nordic ble device is not getting advertised or discoverd in my phone after running secure ble

[Vidar Berg]

Hello,

There can be a number of reasons for the device to not be discoverable, so we need more information to be able help find the problem. Here are some follow up questions that comes to mind:

1. What SDK version are you using?

2. Are you using a custom board or a nordic dev board.

3. Do you have any debug logs

4. Have you tried debugging the code to see if it crashes/get stuck somewhere? In that case, can you post a screenshot to show us what you see?

5. Are you able to discover the board with other BLE examples

 im getting this error while debugging ble buttonless 

[Vidar Berg]

The buttonless template app requires a bootloader to be present in order to run, can you please try another example to confirm normal BLE examples run ok on your board? For instance, the ble_app_blinky example (\ble_peripheral\ble_app_blinky\pca10040e).

ble app blinky one works but while debugging after selecting files like main.c,nrfx clock and ses startup etc.. its showing overlap and cant download files.
