Mesh SDK 3.0.0 timeslot_sd_event_handler

[luciom]

Hi,

I just completed the migration from mesh sdk 2.2.0 to 3.0.0.

After running the project it get stuck at line 422 of timeslot.c in function timeslot_sd_event_handler().

Can you help?

If you still have issues after comparing the projects I think it may be a good idea to turn the case into private and you can send us part of your code so our mesh team can have a look at it. Let me know how it goes.

Hi Lucio,

I tried to migrated a project of my own to the new Mesh SDK v3.0.0 today as well.

The new SDK has added a file called ble_softdevice_support.c, which has replaced the initialization phase of the softdevice handler, the BLE stack, the gap module and the connection parameters negotiaton module. The documentation for the module is here https://www.nordicsemi.com/en/DocLib/Content/SDK_Doc/Mesh_SDK/v3-0-0/group__BLE__SOFTDEVICE__SUPPORT#details

The on_sd_evt handler function and observer are already called in ble_softdevice_support.c so I had to remove the following lines from my main.c:

static void on_sd_evt(uint32_t sd_evt, void * p_context)
{
    (void) nrf_mesh_on_sd_evt(sd_evt);
}

NRF_SDH_SOC_OBSERVER(mesh_observer, NRF_SDH_BLE_STACK_OBSERVER_PRIO, on_sd_evt, NULL);

So on_sd_evt don't get called twice. Could you search in your project and see if you are registering the observer twice? This fixed a timeslot assert for me. It was unclear to me if you still have problems with the assert on sd_radio_request assert, but I hope this was more detailed than my first answer.

Best Regards,

Hi Marjeris,

I confirm that the problem was there.

I removed the lines above and now the application works as expected.

I suggest to add this on the migration guide.

Thank you for your support.
