I have a question about pairing control.

What are you doing in peer_manager_init()? Most examples in the SDK that use the peer manager already have a pm_sec_param_set() call in peer_manager_init() Which would make line 10 redundant. I would try calling the peer_manager_init() in start of main and remove both the pm_sec_params_set(NULL) call and the call in the init function if you have one. You could then only call pm_sec_params_set(&sec_param) in the BSP_EVENT_KEY_2. Notice that it's not recommended to do too much in the interrupt handlers as it can interfere with other priority tasks.

Elaborate more on this. Does the function call return any errors?

Thank you for your answer. I'm sorry, but I'm not sure yet.

I think it's a simple problem, but I'm sorry to keep asking you.

I wrote it like this so I wouldn't pair up at the beginning.

(For your information, I combined 'ble_app_uart' and 'peer_manager'.)

int main(void)
{
    uint32_t err_code;
    err_code = pm_sec_params_set(NULL);
    APP_ERROR_CHECK(err_code);
.
.
}

So it doesn't pairing at first.

And this code enables pairing with button input.

void bsp_event_handler(bsp_event_t event)
{
    uint32_t err_code;
    switch (event)
    {
.
.
         case BSP_EVENT_KEY_2: //button3
            //peer_manager_init(); //Not doing nothing
            //err_code = pm_sec_params_set(&sec_param); //error
            //APP_ERROR_CHECK(err_code);
            break;
    }
}

I tried this, but I think I did something wrong.

What do I need to enter in the parameters for pm_sec_params_set()?

Hi,

You can try calling pm_sec_params_set() and passing the initial parameter that is used when first initializing the module.

And to start pairing with buttons, should I modify it at the button input of the function 'bsp_evt_handler'?

Yes, I think this should work.
