Issue with Sending generic level messages from main()

[DeveloperZ]

Hi,

I am working with a motion sensor which sends a message when it detects a motion. I am communicating between the nRF52 DK and the sensor via UART. I am able to receive messages correctly. I am using the experimental_dimming_client example and I tried to send a generic level message whenever the sensor detects the motion. I added the UART library and added the functionality to send generic level messages upon detecting motion in the main() as follows:

for (;;)
    {
        uint8_t cr;
        while(app_uart_get(&cr) != NRF_SUCCESS);
        while(app_uart_put(cr) != NRF_SUCCESS);

        if(cr == 'M')
        {
            button_event_handler(1);
        }

        (void)sd_app_evt_wait();
    }

M indicates motion and button event handler sends the generic level messages.

Here comes the issue:

I haven't provisioned the board yet. When a motion is detected, the board is able to execute the the button_event_handler function for case 1 which is sending a set message.

Now I provisioned the device(didn't set the publication address). For these two situations, output looks like this:

When I add the publication address, it asserts an error: 

app_error_weak.c,  108, Mesh assert at 0x0002AEC6 (:0)

After this, I went back to the stock SDK and tried to send generic level messages from the main function (without UART) which resulted in a Mesh error 15 (Forbidden Command)

I have been trying to debug and find why I am unable to publish messages to an address from the main() but I am not successful yet.

What might be the reason? Any ideas on how to resolve it?

Thank you.

Hi,

Which function are giving you this error? Which nRF5 SDK and Mesh SDK are you using?

Hi Martin,

I have been using 15.2.0 SDK and  3.0.0 Mesh SDK.

I have been trying to debug the error but it was showing an error from the access_model_reliable_publish() function that is executed before sending the generic level message. If I dig deep into the function, it shows an error at a different function each time I start a new debug stint. 

If I try to send an unacknowledged generic level delta_set message, it results in a mesh error 15 i.e, forbidden command.

Can't we send the generic level messages from the main() but send them by pressing the buttons on the board? How?

Thank you.

I'm little bit confused. Which error code do you get from access_model_reliable_publish()? Or do you get mesh error 15 from this function? You should be able to send messages from main(), seems like the issue is elsewhere.

May be you can try this issue by just calling button_event_handler() function in the main() of the dimming client example something like this:

for (;;)
    {
        
        button_event_handler(1);

        (void)sd_app_evt_wait();
    }

Later after provisioning using app and applying a publication address, 

I was getting a mesh_assert when sending acknowledged messages and mesh error 15 when sending unacknowledged messages.

Hi, 

I was trying a similar thing with light_switch example. In the light switch client, I did something similar:

int main(void)
{
    initialize();
    start();

    for (;;)
    {
        button_event_handler(1);
        nrf_delay_ms(2000);
        (void)sd_app_evt_wait();
    }
}

Initially, I already setup a mesh with a Mesh switch(CLIENT) publishing to an address and Mesh light(SERVER) subscribed to that address. When I run the example after adding button_event_handler in the main(), I see the following forbidden command error:

Any idea on why this error is occuring?
