How to get a notification of ble event

[ting²]

Hi,

I want to get a notification when the BLE event is started, in order to start a timer just after. How can I get that?

I want to clarify my question : My board is acting like a broadcaster. Every second, it emits by BLE communication a packet by interruption. And there is a sniffer. I want to turn on a led, each time a packet is received by the sniffer.

Thanks

thank you for you answer! I am using "softdevice_ble_evt_handler_set()", but it is not working. What i am trying to do is to turn on a led, every time there is a BLE communication interruption.

By using that function it should have call your function.
From the Example code err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch); Which calls static void ble_evt_dispatch(ble_evt_t * p_ble_evt) And that is where it gets process and that is were you should have been able to do it.

I did this too, but it did not work. When I did this, I checked that the "softdevice_ble_evt_handler_set(ble_evt_dispatch)" initialization is successful. But the function "ble_evt_dispatch" is never called.
