Thread network commissionning (with Bluetooth)

[QuentinD]

Hello

I would like to commission my Thread network but my Thread network is isolated (I have no wifi) but I have bluetooth which works in parallel to the Thread network (app based on the "ble_thread_dyn_mtd_coap_cli_pca10056_s140" example ).

Would it be possible to use bluetooth to commission the Thread network (add a new device to the Thread network)? If yes, what do you advise me to be able to do that?

Thank you

Hello Edvin,

Yes you can test this on the example "ble_thread_dyn_mtd_coap_cli_pca10056_s140".

For example, after initializing the thread by auto-commissioning, execute the following functions to create a new network and commission a new device:

otError error = OT_ERROR_NONE;  

//Creation of a new dataset:
error = otDatasetCreateNewNetwork(thread_ot_instance_get(), &sDataset);
ASSERT(error == OT_ERROR_NONE);

//Active the new dataset:
error = otDatasetSetActive(thread_ot_instance_get(), &sDataset);
ASSERT(error == OT_ERROR_NONE);

error = otIp6SetEnabled(thread_ot_instance_get(), true);
ASSERT(error == OT_ERROR_NONE);
error = otThreadSetEnabled(thread_ot_instance_get(), true);
ASSERT(error == OT_ERROR_NONE);

error = otCommissionerStart(thread_ot_instance_get(), NULL, NULL, thread_ot_instance_get());
ASSERT((error == OT_ERROR_NONE) || (error == OT_ERROR_ALREADY)); 

uint8_t eui64[8];  
for(int i=0; i<8; i++)
{
    eui64[i]=i;
}
error = otCommissionerAddJoiner(thread_ot_instance_get(), &eui64, "N0RD1C", 120);
ASSERT(error == OT_ERROR_NONE);

Hello,

I see. I also struggle with the return values of these calls. I did some other changes to the project, such as disabling autostart by setting .autostart_disable = true in thread_instance_init():

static void thread_instance_init(void)
{
    thread_configuration_t thread_configuration =
    {
        .radio_mode            = THREAD_RADIO_MODE_RX_OFF_WHEN_IDLE,
        .autocommissioning     = true,
        .poll_period           = 2500,
        .default_child_timeout = 10,
        .autostart_disable     = true
    };

    thread_init(&thread_configuration);
    thread_state_changed_callback_set(thread_state_changed_callback);
}

I see that it makes a difference if I call otCommissionerStart() or not, because it gives a different callback to thread_state_changed_callback(), but it still returns the error, and so does otCommissionerAddJoiner().

I have forwarded this to our Thread team. I'll let you know when I hear from them.

Best regards,

Edvin

Ok I await your response.

Thank you very much for your help.

Hi,

Sorry for hijacking this thread but I have similar issue and I want to know answer of original question of thread.

I am facing similar issue. I am using ble_thread_dyn_proximity_uart_pca10056_s140 as I want to use COAP server as commissioner. as this project included optimized FTD Open thread library by default and I want it to be a commissioner so I removed it and added FTD library. and modified code as I understand commissioning process.    

When I call otCommissionerStart() it returns OT_ERROR_ALREADY and another thing is that if I call otInstanceFactoryReset(thread_ot_instance_get()); it jumps to error handler.

I am attaching my code for your review. What I want to do is commission a new device to a  network.,ble_thread_dyn_proximity_SR_COAP_Server.rar

Hardik Harpal

Hi Edvin,

I've been waiting for 3 weeks: do you have any news?

Thank you
