There used to be GAP events (connect/disconnect). The main purpose for
these events was to allow applications to re-start advertisement when a
connection was lost - on nrf. Unfortunately things work differently on
Linux, which already has this behavior and for which I haven't yet
implemented these events. Therefore I have removed these events and
instead added code to automatically restart advertisement on connection
loss.
Supporting multiple (incoming) connections as a peripheral would be
useful, but is not currently supported.
All initialization can be done in the Enable call. This makes the API a
bit simpler and a bit more consistent between Nordic chips and other BLE
interfaces.
The nrf51822 chip is still widely available, for example in the BBC
micro:bit. Therefore it's a good idea to support it too.
Unfortunately, Nordic decided to change the API in some significant ways
so many parts are not compatible between S110 for nrf51 and the other
nrf52* SoftDevices.
