Infinite Advertisement in ble_app_buttonless_dfu example project?

[pradeep8892]

Hi All,

To enable infinite advertisement in ble_app_buttonless_dfu example, I di following change

#define APP_ADV_DURATION                0            //18000  

But after this change, the device stopped advertising and every time stuck at NRF_BREAKPOINT_COND.

after analyzing and putting a breakpoint in app_error_handler_bare function, I am getting error code 4 and that is NRF_ERROR_NO_MEM.

So how can i resolve this error? 

Regards,

Pradeep

Hello Pradeep,

To see what function that triggered the error, please add "DEBUG" to your preprocessor definitions, and the log should print what function that caused the issue.

What the issue means depends on what function that returned the value.

When you want to set the advertising duration to 0 (infinite), you must also set the flag

BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE
instead of 
BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE in your main.c file.

Try this, and see if it helps.

Another possible issue in that example is that this example requires a bootloader in order to work properly? Is it intentional that you use this example specifically? If not, perhaps you should try another one, such as the ble_app_uart example.

If you intend to use this example, make sure you compile and flash a bootloader before you flash this example. You also need to generate bootloader settings, program them, and program your ble_app_buttonless project using the generated .hex file, and not the IDE itself. If you want to debug, you must select "attach debugger", instead of "build and debug".

Best regards,

Edvin
