adding beacon to BLE LED/Button service

[xtian]

good day,

is it possible to add beacon to bled led/button example. If the device is not connected and the button is pressed, we would like it to start broadcasting as beacon.

but if the device is paired/connected, it would be like the normal ble led/button behavior where it is going to send 1 if button is pressed.

using pca10040 with sdk 17.1

Hi xtian,

Yes, this is possible. You can just modify the options in the button_event_handler() or its equivalent in the example you are working on.

However, for most of our examples, I believe the application's behavior is to start advertising when the device is disconnected. What kind of advertisement do you want to broadcast?

any example code modified the button_event_handler

[Hieu]

void bsp_event_handler(bsp_event_t event)
{
    uint32_t err_code;
    switch (event)
    {
        case BSP_EVENT_KEY_0:
            if(<advertsing module is not already in advertising mode>)
            {
                ble_advertising_start(your parameter here);
            }
            break;
    }
}

sorry for late reply.

instead of button example, how about changing from uart example to beacon example. so initially it will be using gatts service and change to beacon mode when button is pressed.

do i need to uninitialize something?

Hi xtian,

You shouldn't need to deinitialize anything. However, if you need the GATT feature to be completely inaccessible after the button is pressed, then you also need to remember to disconnect all existing connection to the device.

the plan is to switch to beacon mode when no devices are connected if the button is pressed. so i just need to call the advertising_start function for beacon?
