Hi xtian,

Please refer to this blog post then: How to update advertising data dynamically using BLE Advertising library .

hi,

the first one is correct. initially, it will be like the BLE_UART example where it is connectable but we also want it to be like the BLE_APP_BEACON (non-connectable) example when a button is pressed when no devices are connected and it's advertising. and when it is acting as beacon, we want it to be able switch back to BLE_UART (connectable) example if the button is pressed.

Hi xtian,

I may have misunderstood you. I thought by "beacon" you mean a device making non-connectable advertising to broadcast certain data.

If I understand you correctly now, your use case is: When a device is disconnected, it makes connectable advertising so that a new Central device can reconnect to it.

Is that right?

If so, then almost all of our Peripheral examples already work like that. I am sure the UART/Serial Port Emulation over BLE example does it.

The behavior is realized by the Advertising Module library. Please go over its documentation for more information.

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?

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.

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?

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;
    }
}

any example code modified the button_event_handler

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?
