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 ).

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?

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. 

[Edvin]

But then you basically have the same project as the DFU, except that you don't have the same project settings as in the DFU project. Is your plan to add the light switch client afterwards?

Have you tried to do some debugging? Can you explain what you mean by "DFU doesn't work"?

Have you tried to do any debugging? Did you receive any of the DFU events?

BR,

Edvin

I did it because  i couldn't adjust light switch example to work in DFU mode and at the very last just had replaced main.c.

I am debugging via RTT and yes there are no events.
