nrf51 add ota dfu service on hrs_scanner or ble_nus example

hi all,

I have added the dfu service in one of example of sdk_11 ble_scanner_hrs I followed all help available on this forum and made sucessfuly compiled code but it stopped advertising?

any help is appreciate I have attached my main file

I have attached the bootloder_util.c ,ble_dfu.c,dfu_app_handler.c and made changes according it.

I also changed ram setting in keil.

Thanks in advance

  • Did you flash a bootloader before running this project?

    If it is not too late, I recommend you to start with the bootloader in SDK12.3.0, as it is much easier to get familiar with, since it has a debug version of the bootloader, meaning you can debug it. Since it doesn't check whether or not the application is valid or not, it will always run the application if an application is present, without checking if it is valid. The challenge with debugging with the bootloader is that if you try to debug, then your IDE will upload a new image of your application from your .elf file or .out file, and not the actual .hex file itself, so it will be a bit different. However, you may try to debug with your bootloader from SDK11. Does that work?

    So:

    1: did you flash the bootloader?

    2: are you able to debug your application while the bootloader is present?

    BR,

    Edvin

  • sdk11 its work with scanner code but didn't try with nus_service I am aware of bootloader and flash the bootloader file from sdk11?

    Does sdk11 bootloader different with sdk12.3.0?

    I have ported DFU in ble_scanner code with the reference in blr_hrs_dfu.

  • Yes. The bootloader from SDK11.0.0 and SDK12.3.0 are different. If you use the bootloader from SDK12.3.0, you will have to use the softdevice from SDK12.3.0 as well. So this is only if you have not come too far in the development.

    Did your application advertise before you added the DFU service? I can't test your application. If you want me to, send the entire project folder, including the project file (Keil application file).

    And I didn't understand your answer, but did you flash the bootloader before running the application? How did you program the application? Did you do it via DFU, or the programmer? if programmer, did you use nrfjprog, nrfutil, nRFgo Studio, or your IDE (keil?)

  • Hi I programmed the Softdevice and bootloader for SDK11 with nrfgo Studio and device is advertising also and connect the device and do DFu.

    But for attached file stucked at nus_c_inti() function. I Ported nus service in sdk 11._ble_peripheral/ble_app_hrs

    1541.ble_app_hrs.rar

  • So this issue is not related to the bootloader?

    Where in nus_c_init() does it stop? Is it one of the APP_ERROR_CHECK(err_code) that receives an err_code != 0? If so, what is returned?

    I can't compile your project, because you use complete paths: 

    #include "D:\SDK_Nordic\nRF5_SDK_11.0.0_89a8197\components\ble\ble_services\ble_nus_c\ble_nus_c.h"
    #include "D:\SDK_Nordic\nRF5_SDK_11.0.0_89a8197\components\libraries\uart\app_uart.h"

    I tried to fix this, but then it complained about files missing. Which project file did you use? I tried both s130 and s130_with_dfu, but none of them compiled when I changed the path for the ble_nus_c.h and app_uart.h files. It is still missing a lot of files. I just want to make sure I use the same project as you, so I don't spend a lot of time fixing something you do not use.

    Also, can you check where in nus_c_init() it gets "stuck"?

    BR,

    Edvin

  • sorry for late reply and I have attached new file please add this folder to the sdk11/example/ble_central/ble_app_uart_c Hope it solve file inclusion errorsble_app_uart_c.rar

    I have working on the same code.

  • Ok. I see.

    If you try to run your example in Keil. Try to disable your optimization. Go to your project settings (Options for target) -> C/C++ -> Optimization -> Level 0 (-O0). While you are there, add DEBUG to your Preprocessor Symbols.

    Then recompile your project, and set a breakpoint on line 54 in app_error.c.

    Does it stop there? If so, what are your .line_num, .p_file_name and .err_code? Add error_info to watch by right clicking it, and select 'add error_info to -> Watch 1'.

    You should see what file, line number and what the err_code is. Then find this place in your project, and see what function that returned this.

    Best regards,

    Edvin

  • ok I will do check and come back mean while can you tell me how can I print MAC address and RSSI in below code

    static void beacon_evt_handler(ble_scan_beacon_evt_t * p_evt)
    {
        uint32_t err_code;
    
        if((p_evt->rcv_adv_packet.adv_data.major    == SEARCHED_MAJOR)
         &&(p_evt->rcv_adv_packet.adv_data.minor    == SEARCHED_MINOR)
         &&(p_evt->rcv_adv_packet.adv_data.manuf_id == APP_COMPANY_IDENTIFIER)
    		)
        {
    			  printf("\nMAJOR=%d\n",p_evt->rcv_adv_packet.adv_data.major);
    			  printf("\nMINOR=%d\n",p_evt->rcv_adv_packet.adv_data.minor);
    			  printf("\nNordicid=%d\n",p_evt->rcv_adv_packet.adv_data.manuf_id);
    			  printf("\nrssi=%d\n",p_evt->rcv_adv_packet.adv_data.rssi);
    			  printf("\nuuid=%d\n",p_evt->rcv_adv_packet.adv_data.uuid);
            err_code = bsp_indication_set(BSP_INDICATE_ALERT_3);
            APP_ERROR_CHECK(err_code);
        }
    }

    Also checked as you suggest didn't get error_info but  while I debug it took the code to place as seen in below imageerror
