1) This seems really strange, can you provide the exact step you have done?

2) Sorry, seems like I missed it.

3) When debugging can you see if the code enters your uart handler at all? Set a breakpoint inside the handler and see if it enters when you send data. The first thing would be to get the uart part to work first. Make sure that you can receive anything via UART at all.

Hi Mttrinh,

1) I have tried with freshly downloaded sdks but still face the same issue.

2) I have called uart_init() in the initialize function of main.c attaching the code,

static void initialize(void)
{
    
      uart_init();
   
   // __LOG_INIT(LOG_SRC_APP | LOG_SRC_ACCESS, LOG_LEVEL_INFO, LOG_CALLBACK_DEFAULT);
    __LOG_INIT(LOG_SRC_APP | LOG_SRC_FRIEND, LOG_LEVEL_DBG1, log_callback_rtt);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- BLE Mesh Static Provisioner Demo -----\n");

    ERROR_CHECK(app_timer_init());
    hal_leds_init();

#if BUTTON_BOARD
    ERROR_CHECK(hal_buttons_init(button_event_handler));
#endif

    ble_stack_init();
    mesh_init();
    node_setup_uri_check();
}

3) I have debugged this but not able to find out why it is not happening, i have put condition for scanning and resetting the does but not able to perform, not even able to reset the node. Can you find any memory issue, when i am pressing 4 nothing is coming as response, according to uart_event_handler it should reset the node, attaching the uart_event_handler which i have implemented for the desired output:

void uart_event_handler(app_uart_evt_t * p_event)
{
    static uint8_t data_array[244];
    static uint8_t index = 0;
   // static uint8_t val = 0;
    uint32_t       err_code;

     //printf("\r\nUART started uart event handler.\r\n");
    switch (p_event->evt_type)
    {
        case APP_UART_DATA_READY:
        {
            UNUSED_VARIABLE(app_uart_get(&data_array[index]));
            printf("Data array in switch %c\r\n",data_array[index]);

            index++;

             if ( data_array[index - 1] == '1')
            {
               printf("Sucess pressed 1 \r\n");
               check_network_state();
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

            }

            if ( data_array[index - 1] == '2')
            {
               printf("Sucess pressed 2 \r\n");
               provisioning_resume();
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

            }

             if ( data_array[index - 1] == '4')
              {
               printf("Sucess pressed 4 \r\n");
             
                 if (mesh_stack_is_device_provisioned())
                 {
                   /* Clear all the states to reset the node. */
                   provisioner_invalidate();
                   mesh_stack_config_clear();
                 }
               node_reset();
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

              }

                
            #if 0
            if ( data_array[index - 1] == ';')
            {
               printf("sucess \r\n");
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

            }
            #endif
           
                
            break;
            }

        case APP_UART_COMMUNICATION_ERROR:
            APP_ERROR_HANDLER(p_event->data.error_communication);
            break;

        case APP_UART_FIFO_ERROR:
            APP_ERROR_HANDLER(p_event->data.error_code);
            break;

        default:
            break;
    }
  }

Can you please help me with this?

Thanks & Regards,

Ela

[quote user="Ekta hav"]1) Yes i have copied the ble_app_uart_coexist folder into ble_peripheral folder and set the MESH_ROOT in global macros to the mesh sdk path.[/quote]

This is strange, I would suggest you try download a fresh copy of the SDKs and see if that helpes solve this.

As for the implementation, unfortunately we don't have an exact example to show you how to do this. Your implementation of your uart handler seems correct. Have you tried debugging through the code to see what happens? Does the code enter the uart handler when you send the commands?

It looks like in your main that you don't call uart_init()?

Hi Mttrinh,

It will be very helpful if a working code can be provided as reference for the desired output.

Hi Mttrinh,

Can you please provide the implementation code for using UART logging for provisioner example code in mesh sdk , so that we are able to provision the unprovisioned nodes.

I have shared the implementation with you, but not able to achieve the desired result, not able to provision the unprovisioned nodes. I am attaching the main.c file what i have used for the UART logging and getting provision event handlers in uart_event_handler.

It will be very helpful if i can get the quickest response as its been long raising this issue, causing delay for me, i hope you understand .

RE: How to send data to UART for the provisioner example of mesh sdk.

Ela — Tue, 16 Mar 2021 08:40:42 GMT

Hi Mttrinh,

1) Yes i have copied the ble_app_uart_coexist folder into ble_peripheral folder and set the MESH_ROOT in global macros to the mesh sdk path.

2) In UART example there is not uart_event_handle function. I have implemented the uart_event_handler as per my application, attaching that code :

void uart_event_handler(app_uart_evt_t * p_event)
{
    static uint8_t data_array[244];
    static uint8_t index = 0;
   // static uint8_t val = 0;
    uint32_t       err_code;

     //printf("\r\nUART started uart event handler.\r\n");
    switch (p_event->evt_type)
    {
        case APP_UART_DATA_READY:
            UNUSED_VARIABLE(app_uart_get(&data_array[index]));
            printf("Data array in switch %c\r\n",data_array[index]);

            index++;

             if ( data_array[index - 1] == '1')
            {
               printf("Sucess pressed 1 \r\n");
               check_network_state();
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

            }

            if ( data_array[index - 1] == '2')
            {
               printf("Sucess pressed 2\r\n");
               provisioning_resume();
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

            }

             if ( data_array[index - 1] == '4')
              {
               printf("Sucess pressed 4 \r\n");
             
                 if (mesh_stack_is_device_provisioned())
                 {
                   /* Clear all the states to reset the node. */
                   provisioner_invalidate();
                   mesh_stack_config_clear();
                }
               node_reset();
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

              }

                
            #if 0
            if ( data_array[index - 1] == ';')
            {
               printf("sucess \r\n");
               index = 0;
               memset(data_array[index], 0 , sizeof(data_array[index]));

            }
            #endif

                
            break;

        case APP_UART_COMMUNICATION_ERROR:
            APP_ERROR_HANDLER(p_event->data.error_communication);
            break;

        case APP_UART_FIFO_ERROR:

            break;

        default:
            break;
    }
  }

Is this the right way to do this? As i am not able to get command response after sometime. If i am pressing 4 nothing is happening some random letter is getting printed. If i am pressing 2 not able to recive back any command. What i am missing here, can you please let me know?

Thanks & Regards,

RE: How to send data to UART for the provisioner example of mesh sdk.

Mttrinh — Mon, 15 Mar 2021 15:39:12 GMT

Hi,

1) Did you copy the coexist folder into the examples/ble_peripheral folder at your nRF5 SDK installation path? Did you add the MESH_ROOT macro to the Global macros in SES?

2) The function is called uart_event_handle in the UART example. ble_nus_data_send() is the function that sends the data over BLE, you can remove this.

Ela — Mon, 15 Mar 2021 09:32:06 GMT

Hi Mtrrinh,

In uart example of nrf sdk, there is no uart_event_handler, there is uart_error_handler. In ble_app_uart example of nrf sdk there is uart_event_handler where it is sending uart recieved data over ble, can you tell me how to not include the sending data over ble in that event handler.

Thanks & Regards,

2) I have implemented the uart_event_handler, i press 1 from serial terminal i am able to scan all the unprovisioned nodes and then provisioned them, when press 4 reset all the provisioned nodes, attaching the code implementation i have added :

void uart_event_handle(app_uart_evt_t * p_event)
{
  //   printf("\r\nUART started uart event handler provisioner code .\r\n");

       while (true)
    {

        while (app_uart_put(cr) != NRF_SUCCESS);
 
        if (cr == '1')
        {

            check_network_state();

            while (true)
            {
                // Do nothing.
            }
        if (cr == '2')
        {
        printf("\r\n 2 pressed ");
        provisioning_resume();

         while (true)
            {
                // Do nothing.
            }

        }
        if (cr == '4')

            {
                /* Clear all the states to reset the node. */
                provisioner_invalidate();
                mesh_stack_config_clear();

        }
         

        }
    }
    
#if 0    
    uint32_t i;
    switch(i)
    {
    case 1:
    {
     printf("\r\n Pressing 1 for scanning the unprovisioned nodes Uart event handler provisioner code .\r\n");
     check_network_state();
     break;

    }
    
    case 2: 

      {
            provisioning_resume();
            break;
       }

    case 4:
         {

                provisioner_invalidate();
                mesh_stack_config_clear();
            }
            node_reset();
            break;
        }
    break;
    default:

    }
#endif
}

But here i am not able to get the desired result, is this the right way to do, if not hen how shall i do this, can you attach code implementation for my application for reference.

Response to this at high priority is really a great help..

Thanks & Regards,

RE: How to send data to UART for the provisioner example of mesh sdk.

Hi,

[quote user="Ekta hav"] I am getting compiling errors and not able to resolve it, i have used in the same way as mentioned in the infocenter. [/quote]

Can you provide more details about the compiling errors? Any logs?

[quote user="Ekta hav"]In our provisioner example code, segger_printf.c, segger_print.c, rttinput.c these files have been used for writing or reading data to RTT. "SEGGER_RTT_Read" and "SEGGER_RTT_Write" these functions are used for getting and sending data by RTT, so can i use these functions for the same operation with UART, i think we can not use these functions, if not then how shall we do it?[/quote]

No, these functions are for RTT. You can't use the same functions for UART.

Yes, you have to create a UART event handler that handles the incoming commands. I suggest you look at the uart_event_handler from the UART example from the nRF5 SDK. It will show you how to get data from the serial terminal. Implement something similar to app_rtt_input_handler(), which is how the RTT input is handled, inside the uart_event_handler to handle your inputs via UART.

RE: How to send data to UART for the provisioner example of mesh sdk.

Hi Mttrinh,

1) In our provisioner example code, segger_printf.c, segger_print.c, rttinput.c these files have been used for writing or reading data to RTT. "SEGGER_RTT_Read" and "SEGGER_RTT_Write" these functions are used for getting and sending data by RTT, so can i use these functions for the same operation with UART, i think we can not use these functions, if not then how shall we do it?

2) I have created "uart_event_handler" to handle 2 commands for press 1 and 4 for initiating some commands using "app_uart_get" and "app_uart_put" to send and get data from serial terminal, i am using putty for this. Can i use this way, as i tried but not getting the desired result as mentioned in above point.

Attaching the code snippet which i have implemented for the uart_event_handler:

RE: How to send data to UART for the provisioner example of mesh sdk.

Ela — Thu, 11 Mar 2021 06:30:09 GMT

Hi Mttrinh,

1) I am getting compiling errors and not able to resolve it, i have used in the same way as mentioned in the infocenter.

2) Can you please elaborate about when you mean have to handle how received command is being handled? For example : if i want to send press 1 to initiate the scanning of unprovisioned device as same in provisioner example code and want to send press button 4 to reset all the provisioned nodes using UART. In the existing example code we are sending using RTT same i want to do using UART.What do you mean that handle the received commands. Shall i put uart event handler with the case 1 calling funcciton to scan the unprovisioned nodes and case 4 call function to reset the provisioned node? Can you just help me with this at high priority, it will be very helpful.

Thanks & Regards,

Ela

RE: How to send data to UART for the provisioner example of mesh sdk.

Mttrinh — Tue, 09 Mar 2021 18:13:32 GMT

Hi,

1) What kind of errors do you get? You run the example unmodified, correct?

2) You shouldn't need to add backend logging via UART. I haven't tried to add UART logging to the provisioner example myself, so I would need some time to try this. In the mean time I would suggest you study the proximity coexist example and see how things are done there.

I think it should be possible to do the same with UART, but you have to implement how the received commands are handled yourself.

Hi Mttrinh,

Hi Mttrinh,

1) I was using coexist example but i am not able to compile the code as throwing some of the errors, i have done the same way it is mentioned in the infocenter for coexist example, but still not able to test the coexist example.

2) I have tried merging the code, but it did not work for me. I have doubt about logging module, as we do have backend logging too in the sdk. In mesh sdk we are using log.c file for logging via RTT but in nrf sdk we are using backend logging via RTT as in file nrf_backend_rtt.c . As, i want tio use provisioner code of the mesh sdk, which logging shall i used, shall i made changes only in log.c file or shall i add backend logging via UART. I have tried both but nothing worked, when tried doing changes in log.c file having lot of errors when added backend logging for UART. Can you please help me in achieving this, if possible by providing changes need to be done or added in the provisioner code, it will be of great help.

Thanks & Regards,

Ela

Hi,

1) I suggest you look at the proximity coexist example you can see how the logging over UART is initialized instead of RTT. Then try to merge this logging functionality over to your application.

2) We do have an example in the SDK that combines UART with the light switch example. You can use this as a reference for how you can combine the uart example and the provisioner example. This is not something we have done so you have to try implementing yourself.

3) Like it is mentioned here, only a few examples supports the dongle but with limited functionalities. It might be possible to modify the example so that it can run on the dongle, I would not recommend using the dongle since it lacks a onboard debugger and only light switch server example has been tested with the dongle.
