Lifght switch client example with DFU issue

[UdjinPr]

I use 3.10 mesh sd and 2 dk boards.

DFU example works fine, but when I try to implement dfu mode in ls example I can't achieve goal. DFU doesn't work. I follow the instruction of the dfu example, but Istead of the dfu hex file I use hex file from the ls client project with some correction and get no reaction after start of  dfu mode. At the very last I changed main.c in the ls client example from dfu project and result the same. I double checked sdk config and macros placement they are the same. 

I have no idea about it ).

and some important details: on master node(board which is used for transmission) is used original dfu example, and on the slave board I off serial driver, becouse it clashes with saadc.

Hello,

Did you add the mesh event callback for the DFU events in your light switch clients?

static void mesh_evt_handler(const nrf_mesh_evt_t* p_evt)
{
    switch (p_evt->type)
    {
        case NRF_MESH_EVT_DFU_FIRMWARE_OUTDATED:
        case NRF_MESH_EVT_DFU_FIRMWARE_OUTDATED_NO_AUTH:
            if (fw_updated_event_is_for_me(&p_evt->params.dfu))
            {
                ERROR_CHECK(nrf_mesh_dfu_request(p_evt->params.dfu.fw_outdated.transfer.dfu_type,
                                                 &p_evt->params.dfu.fw_outdated.transfer.id,
                                                 (uint32_t*) bank_addr));
                hal_led_mask_set(LEDS_MASK, false); /* Turn off all LEDs */
            }
            else
            {
                ERROR_CHECK(nrf_mesh_dfu_relay(p_evt->params.dfu.fw_outdated.transfer.dfu_type,
                                               &p_evt->params.dfu.fw_outdated.transfer.id));
            }
            break;

        case NRF_MESH_EVT_DFU_START:
            hal_led_mask_set(BSP_LED_0_MASK | BSP_LED_2_MASK, true);
            break;

        case NRF_MESH_EVT_DFU_END:
            hal_led_mask_set(LEDS_MASK, false); /* Turn off all LEDs */
            hal_led_mask_set(BSP_LED_0_MASK | BSP_LED_1_MASK, true); /* Yellow */
            break;

        case NRF_MESH_EVT_DFU_BANK_AVAILABLE:
            hal_led_mask_set(LEDS_MASK, false); /* Turn off all LEDs */
            ERROR_CHECK(nrf_mesh_dfu_bank_flash(p_evt->params.dfu.bank.transfer.dfu_type));
            break;

        default:
            break;

    }
}

Also, I suggest that to get thing up and running, you should use the default DFU example with NRF_MESH_SERIAL_ENABLE = 1 to broadcast the DFU images.

So in your light switch clients, you need the bootloader, that you use when you test the default DFU examples, which you can find in:

SDK\bin\bootloader\gccarmemb\mesh_bootloader_gccarmemb_nrf52832_xxAA.hex

Then, you make sure that inside main() -> initialize() -> mesh_init() -> nrf_mesh_evt_handler_add(&m_evt_handler);

with m_evt_handler.mesh_evt_handler;

and mesh_evt_handler() is the one that I pasted in the snippet above.

Also, make sure that nrf_mesh_dfu_enable() is called, like it is in the dfu example:

main() -> start() -> mesh_stack_start() -> nrf_mesh_enable() -> nrf_mesh_dfu_enable()

Is "HOST" Defined in your light_switch client project?

Best regards,

Hello, Thank you for your reply. As i sad before I copied main.c from dfu exampel and replaced it main.c in ls example.

Yes, It is enaeble.

I use bootloader and a device page as in the dfu example.

I have nrf_mesh_evt_handler_add() in main.c becouse of i use main.c from dfu example.

I double checked, it is called. 

and about HOST. I suppose it is difined, but i couldn't finde place where. 

[Edvin]

Have you just replaced the main.c in the light_switch\client example with the main.c file from the dfu example?

[UdjinPr]

Yes I have,  I thought in this case it must work.
