Just in case someone needs to do this. The way I Solved it is by doing the following:

1) Right after:
BLEDevice::init("DeviceName");
Add:

BLEDevice::setCustomGapHandler(my_gap_event_handler);

Where : my_gap_event_handler is a callback function that looks like this:

static void my_gap_event ...

Anyone?

Should I switch to client instead of server ? But I need multiple connections.

Any help welcomed.
